What is the probability that a data value in a normal distribution is between a z-score of -0.18 and a z-score of 1.23? Round your answer to the nearest tenth of a percent. O A. 65.0% B. 55.3% C. 46.2% D. 84.3% SUBMIT
Answer:
C
Step-by-step explanation:
Zscore = - 0.18 ; Z = 1.23
To find the percentage :
P(Z< 1.23) - P(Z < - 0.18)
Using the Z probability calculator :
P(Z < - 0.18) = 0.42858
P(Z < 1.23) = 0.89065
0.89065 - 0.42858
= 0.46207
= 46.2%
Find the volume of the composite figure.
Please help me quickly, thank you
Step-by-step explanation:
P = 5x+2y
P = 5(3)+2(5) = 15+10 = 25 meters
x = 3/25 ×32 = 96/25 = 3.84 meters
y = 5/25 × 32 = 6.4 meters
P = 5x+2y
P = 5(3)+2(5) = 15+10 = 25 meters
x = 3/25 ×32 = 96/25 = 3.84 meters
y = 5/25 × 32 = 6.4 meters

FInd the area of the trapezoids.
Answer:
7.5
Step-by-step explanation:
Take the figure apart to make one rectangle and 2 triangles.
the rectangle with the endpoint T has a width of 3 and a height of 1.
The Area for the rectangle is A = wl = 3 * 1 = 3
The first, smaller triangle with points R and A has a height of 3 and a base of 1.
The Area for the triangle is A = h b/2 = 3 * 1/2 = 1.5
The large triangle with points T and P has a height of 3 and a base of 2.
Using the same formula for the Area of a triangle you get 3
Now add all areas together
3+1.5+3 = 7.5

Part B: If (70)x = 1, what are the possible values of x? Explain your answer. (5 points)
Can you Help Me I NEED ANSWER ASAP!!!
Answer:
see below
Step-by-step explanation:
Part A: (72)^x = 1
Take the log base 72 of each side
log72(72^x) = log 72(1)
We know log a^b = b log a
x log72(72) = log72(1)
x = log72(1)
x = 0
Part A: (70)^x = 1
Take the log base 70 of each side
log70(70^x) = log70(1)
We know log a^b = b log a
x log70(70) = log70(1)
x = log70(1)
x = 0
Simplify the radical completely.
Answer:
D
Step-by-step explanation:
But basically, one by one you try moving the terms out of the radical.
75 is also 25 * 3 and since 25 has a perfect square root of 5 that goes out and 3 stays inside the radical.
x^3 is also x^2 * x and since x^2 has a perfect square root which is just x that goes outside while the remaining x stays inside.
y^9 is also y^8 * y and since we move variables out the radical in twos y^ goes outside the radical and y stays inside alone.
Finally, z is just z it can't be taken out so it stays inside the radical.
Hope that helps!
The sum of two numbers is zero. When 10 times the smaller number is added to 6 times the larger, the result is 3. Find the two numbers.
Answer:
3/4 and -3/4
or
0.75 and -0.75
but there is no solution for
10 times the smaller number added to 6 times the larger number to get 3 as result.
the absolute values of x and y must be equal and with opposite signs (due to their sum being 0).
therefore, 10 times the negative value can never be compensated by 6 times the same but positive value. the sum will always be negative and not positive (and therefore not +3).
it only works with 10 times the larger (positive) number plus 6 times the smaller (negative) value.
Step-by-step explanation:
x + y = 0
10×x + 6×y = 3
=>
x = -y
10×(-y) + 6×y = 3
-10y + 6y = 3
-4y = 3
y = -3/4
=>
x = -y = -(-3/4) = 3/4
control :
10×(3/4) + 6×(-3/4) = 30/4 - 18/4 = 3
12/4 = 3
3 = 3
correct
Please help me with this math problem. Only answer if your sure it’s correct. Pls answer ASAP!
Answer:
Step-by-step explanation:
Using distance formula (search it up, it's BIG) we start by plugging in the coordinates. the second x coordinate minus the first x coordinate is equal to -2 - - 4. You can't subtract a negative from an negative, so you add them. We change it to -2 + + 4 which equals 2. According to the distance formula (look it up), we square that (meaning it's equal to 4) and add it to the y value. The y value is equal to the second y coordinate minus the first y coordinate. This is represented by -3 - 0. This equals -3, but according to the distance formula, we square it which makes it equal to 6. Now, what do we do with the numbers 6 and 4? Following the distance formula, we add them which is equal to 10. Now we are left with the square root of 10 according to the distance formula. Your answer is the square root of 10 or in decimal form, 3.162277......... I hope this helped!

Step-by-step explanation:
Hi there!
We're given the equation y=-75x-50, which represents a submarine DESCENDING towards the ocean floor, where y is the depth in feet, and x is the number of minutes the submarine is descending
Since the submarine is DESCENDING, we can immediately eliminate A and C, which talk about the submarine ASCENDING
That leaves B and D
Looking at the given equation, y=-75x-50, -75 is the slope, or rate of change, and -50 is the y intercept, or the "beginning" (where the equation will "start")
Therefore, the submarine will start at -50 feet, or 50 feet below sea level
As x is the number of minutes the submarine is descending, that means that if the submarine travels 1 minute, it will descend 75 feet (-75*1=-75), at 2 minutes, it'll descend 150 feet (-75*2=-150), and so on
So that means the submarine must be descending at a rate of 75 feet per minute
Therefore D is the correct answer
Hope this helps! Good luck on your assignment :)
Using the equation y=kx and the table below, find the constant of proportionality (k).
Answer:
k = 9/4
Step-by-step explanation:
To find k, use the equation
y = kx
Pick a point
72 = k *32
Divide each side by 32
72/32 = k
9/4 = k
Answer:
k = 9/4
Step-by-step explanation:
Here , we have given equation and we need to find k.
To find k, we have given equation which is y = kx
pick any point from the table and substitute in the equation.
y = kx
We choose :- x = 8 and y = 18
18 = 8 × k
Divide each side by 8
18/8 = k
9 / 4 = k

Simplify the expression
[tex](x + 7)( x - 2)[/tex]
Answer:
x²+5x-14
Step-by-step explanation:
For this equation, you want to use FOIL (multiply first terms, then outside terms, then inside terms, then last terms) to expand the brackets.
This gives x×x+x×-2+x×7+7×-2, which simplifies to x²-2x+7x-14, and further to x²+5x-14.
**This content involves expanding quadratics with FOIL, which you may wish to revise. I'm always happy to help!

why mathematical induction is used ?(write a 100 words paragraph)
Answer:
Mathematical induction is a method of mathematical proof typically used to establish that a given statement is true for all natural numbers ( non-negitive integers). The simplest and most common form of mathematical induction proves that a statement involving a natural number that holds for all values.
Express it in slope-intercept form.
Answer:
y = 1/4x - 4
Step-by-step explanation:
The slope is four points behind the origin, so we subtract -4 from the equation:
y = 1/4x - 4
use two points on the line to find the slope:
(0,-4) (4,2)
Slope = change in y over change in x
Slope = (2 - -4) / (4-0) = 6/4 = 3/2
Y-intercept is the y value when x is 0, the line goes through y=2 at x = 0, so the t intercept is 2
The equation is:
Y = 3/2x + 2

Marcia sells lemonade for $2 per cup and candy for $1.50 per candy bar. She earns $425 selling lemonade and candy bars. If Marcia sold 90 bars of candy, which equation could be used to figure out how many cups of lemonade she sold?
Answer:
145 cups of lemonade; 2x+1.50y=425, where y=90
Step-by-step explanation:
Let us first set up an equation, where x represents number of cups of lemonande, and y represents number of candy bars. We know that every cup of lemonade costs $2, every candy bar sold costs $1.50, and that Marcia sold a total of $425. We now have equation:
[tex]2x+1.50y=425[/tex]
However, we actually know how many candy bars Marcia sold. Therefore, our y value is 90. Let's rewrite the equation:
[tex]2x+1.50*90=425\\2x+135=425\\2x=290\\x=145[/tex]
Therefore, Marcia sold 145 cups of lemonade.
I hope this helps! Let me know if you have any questions :)
Mary plants roseas in 1/4 of her garden. She also plants some tulips in her garden. She has 1/12 of the garden left to plant more flowers. What fraction of Mary's garden has tulips?
Let x represent the full area if Mary's garden.
Mary plants roses in 1/4 of her garden. This means that the portion of the garden on which she planted roses would be 1/4 × x = x/4
She also plants some tulips in her garden. She has 1/12 of the garden left to plant more flowers. This means that the portion if the garden that she has left to plant more flowers would be 1/12 × x = x/12
The portion of the garden on which she planted tulips would be
x - (x/4 + x/12) = x - (3x + x)/12 = x - 4x/12
x - x/3 = (3x - x)/3 = 2x/3
Therefore, the fraction of Mary's garden that has tulips would be
(2x/3) /x = 2/3

Find the surface area of the regular pyramid.
A machine cuts dry wall screws with specifications such that the length of each screw is 1.25 inches with an allowable margin of error of 0.02 inches. Use this information to complete each statement.
Answer:
[tex](a)\ x = 1.25 \± 0.02[/tex]
[tex](b)[/tex]
[tex]Minimum = 1.23in[/tex]
[tex]Maximum = 1.27in[/tex]
Step-by-step explanation:
Given
[tex]L = 1.25in[/tex] --- Length
[tex]E=0.02in[/tex] -- Margin of error
Solving (a): The equation of the length
This is calculated as:
[tex]x = L \± E[/tex]
So, we have:
[tex]x = 1.25 \± 0.02[/tex]
Solving (b): The range of value of x
In (a), we have:
[tex]x = 1.25 \± 0.02[/tex]
Split:
[tex]x = 1.25 - 0.02[/tex] [tex]x = 1.25 + 0.02[/tex]
Solve for x
[tex]x = 1.23[/tex] [tex]x = 1.27[/tex]
So, we have:
[tex]Minimum = 1.23in[/tex]
[tex]Maximum = 1.27in[/tex]
