Answer:
c. 61.25 kg
Step-by-step explanation:
The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean.
a. 15.31 kg
b. 51.40 kg
c. 61.25 kg
d. 80.49 kg
Margin of Error Formula= z × Standard deviation/√n
95% confidence interval = 1.96
Standard deviation = 125kg
n = 16 samples
Margin of error= 1.96 × 125/√16
= 1.96 × 125/4
= 245/4
= 61.25kg
The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean is 61.25kg

A restaurant offers delivery for their pizzas. The total cost is a delivery fee added to the price of the pizzas. One customer pays $25 to have 2 pizzas delivered. Another customer pays $58 for 5 pizzas. How many pizzas are delivered to a customer who pays $80
Answer:
7 pizzas
Step-by-step explanation
First we subtract 58-25=33
Then we subtract 5-2=3
Now, we have 33 over 3 so we divide them and we get 11
So, that means that each pizza costs $11 and the fee that they charge for each pizza is 3.
So if the customer pays $80 that means that he bought 7 pizzas and he payed $3 fee.

If you roll a ball down a ramp, which factor will have the greatest effect on the amount of friction created?
A) Force applied to the ball
B) Speed of the ball
C) Texture of the surface
D) Weight of the ramp
(Here is an image if needed) :
Answer:
C. The Texture of the Surface
Step-by-step explanation:
I know it's confusing because of A.. But if you think about what would happen if you were to bounce a ball with a lot of force onto the surface, it wouldn't cause a difference in the friction because it would still just bounce right back up. D. is also not applicable because the weight of the ramp wouldn't matter if the ball is rolling on top of it.

Evaluate 3/11 × 11/13 Give your answer as a fraction in its simplest form.
Answer: 3/13
Step-by-step explanation:
Your friend says that 14.5% is same as the fraction 29/200. explain whether your friend is correct or incorrect by comparing the two values
14.5% = 0.145
Step-by-step explanation:
The term 'percent' (%) actually means per 100. So when you say 14.5% it means 14.5 per 100. So when you put that into an equation it actually means:
So when you solve it, 14.5% is actually 0.145 and not 14.5.
Your friend is then incorrect because:
14.5% ≠ 14.5
Answer:
Your friend would be correct. 14.5% divided by 100 is equal to 0.145. When you divide 29/200 you also get 0.145, if you multiply it by 100 you get 14.5%.

A rectangle a photo with dimension 3 inches wide by 4 inches long is enlarged to a length of 12 inches what is the width of the enlarged print
Answer:
9 inches wide
Step-by-step explanation:
so in the text it tells you that the rectangle is 3 inches wide by 4 inches long
then it gives you the final length but you need the width. so what i did is find out how much the increase of the length was, the length was4 at the start then ended at 12 to find out how much it increased i divided 12 by 4 and got 3. that shows that the object is 3 times larger so then I multiplied the original width by 3 which would be 3*3 which equals 9. so 9 is the width of the enlarged shape.

The graph shows the number of centimeters a particular plant grows over time. Given the points (0,0) and (6,9), how many centimeters does the plant grow per week?
Answer: 4/5 or 0.8
Step-by-step explanation: To find how much it grows over time, we have to find the slope. to do that, we need to have two points with exact points on the graph, so (0,0) and (4,5). the equation for slope is rise/run. it rises 4, and runs 5. so 4/5.

The perimeter of the rectangle is 2,500 cm. Find the unknown side length. the other side is 750
Answer:
500 cmStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question we have
[tex]2500 = 2l + 2(750) \\ 2500 = 2l + 1500 \\ 2l = 2500 - 1500 \\ 2l = 1000 \\ \frac{2l}{2} = \frac{1000}{2} \\ l = \frac{1000}{2} \\ l = 500[/tex]
We have the final answer as

There were 5 ice cream cones for every 3 brownies sold at the ice cream shop. If there were 24 brownies sold, how many ice cream cones were sold?
Answer:
THe answere is 40
Step-by-step explanation:
If 24 brownies are sold, the number of ice cream cones sold is 40.
A linear equation is in the form:
y = mx + b;
where y, x is variable, m is the rate of change and b is the y intercept.
Let y represent the number of ice cream cones and x represent the number of brownies sold.
Since there were 5 ice cream cones for every 3 brownies sold at the ice cream shop. Hence:
y = (5/3)x
If 24 brownies are sold:
y = (5/3)x
y = (5/3) * 24 = 40
If 24 brownies are sold, the number of ice cream cones sold is 40.
