Step-by-step explanation:
The unit rate for a 9-ounce jar is $0.17.
The unit rate for a 15-ounce jar is $0.17.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
The store sells a 9-ounce jar of mustard for $1.53.
The unit rate.
= 1.53/9
= 0.17 _____(1)
The store sells a 15-ounce for $2.55.
The unit rate.
= 2.55/15
= 0.17 ______(2)
From (1) and (2) we see that,
The unit rate is the same.
Thus,
The unit rate is the same.

The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes. The population standard deviation is known at 0.5 minutes. We want to test to determine whether or not the mean waiting time of all customers is significantly different than 3 minutes. Use a = 0.05. The test statistic is a 1.96 b. 1.64 c. 2.00 d. 0.056 The p-value is a. 0.0456 b. 0.0482 c. 0.4772 d. 0.9759 e. 0.9772 At the 5% level, you a. fail to reject the null hypothesis b. reject the null hypothesis
Answer:
The test statistic is c. 2.00
The p-value is a. 0.0456
At the 5% level, you b. reject the null hypothesis
Step-by-step explanation:
We want to test to determine whether or not the mean waiting time of all customers is significantly different than 3 minutes.
This means that the mean and the alternate hypothesis are:
Null: [tex]H_{0} = 3[/tex]
Alternate: [tex]H_{a} = 3[/tex]
The test-statistic is given by:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Sample of 100 customers.
This means that [tex]n = 100[/tex]
3 tested at the null hypothesis
This means that [tex]\mu = 3[/tex]
The average length of time it took the customers in the sample to check out was 3.1 minutes.
This means that [tex]X = 3.1[/tex]
The population standard deviation is known at 0.5 minutes.
This means that [tex]\sigma = 0.5[/tex]
Value of the test-statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{3.1 - 3}{\frac{0.5}{\sqrt{100}}}[/tex]
[tex]z = 2[/tex]
The test statistic is z = 2.
The p-value is
Mean different than 3, so the pvalue is 2 multiplied by 1 subtracted by the pvalue of Z when z = 2.
z = 2 has a pvalue of 0.9772
2*(1 - 0.9772) = 2*0.0228 = 0.0456
At the 5% level
0.0456 < 0.05, which means that the null hypothesis is rejected.
A tap fills an eighty litre tank in 5 minutes. What is the rate of flow of water with respect to
time, in litres per second?
Answer:
0.27 lt/s
Step-by-step explanation:
80 liters in 5 minutes
5 minutes are 300 seconds (5x60)
We know how many seconds we need to fill up the tank (300 seconds for 80 liters). Now we need to know how many liters we can fill up in 1 second, as the question requires "liters per second".
80 lt / 300 sec
X lt / 1 sec
80 x 1
---------- = X
300
X = 0.2666666...
X = 0.27 lt / s

Is (3,6) a solution of the system of linear equations below? Justify your response. Use of the graph is optional.
-6x + y= -12
X + y= -3
Answer:
No.
Step-by-step explanation:
The given system of equations are :
-6x + y= -12 ......(1)
x + y= -3 ......(2)
Put x = 3 and y = 6 in both equations i.e.
-6(3) + (6) = -12
And
3 + 6 = 9 ≠ -3
Hence, (3,6) is not the solution of the given system of equations.

What is the area of the chalkboard?
O A. 1.53 m2
B. 1.63 m2
OC. 2.6 m2
0
D. 5.2 m2
Help!
Answer:
[tex]A=1.53\ m^2[/tex]
Step-by-step explanation:
The length of a chalkboard, l = 1.7
The width of a chalkboard, b = 0.9 m
We need to find the area of the chalkboard. The formula for the area of a rectangle is given by :
[tex]A=L\times B\\\\A=1.7\times 0.9\\\\A=1.53\ m^2[/tex]
So, the area of the chalkboard is equal to [tex]1.53\ m^2[/tex].

(11+x)/2-(9x-3)/4 x=3
Answer:
(11+X)/2-(9x-3)/4 x=3
subsititute 3 into all x
(11+3)/2-(9*3)-3)/4
first solve the first diviision
2-(9 times 3)-3/4
=2-(27-3)/4
=2-(24)/4
since the "2-" is there, you have to subtract it from 24 before you dividewhich would then be
22/4=5.5(in decimal form)
DON'T forget you have another bracket waiting for you since you were given 3 brackets. bring the first bracket down
2-(9x-3)/4 was solved and we got 5.5, so basically we are "substituting 5.5 into that part of the question)
11+x/5.5
11+3/5.5
14/5.5
=2.54 which is your final answer

yes, the answer is 2.54 I believe.
