Step-by-step explanation:
First multiply 6 by u and 7 to get 6u+7
next add -8u + 6u and get -2u
then subtract 42 from both sides of the equation (28-42)
finally divide -2u from both sides of the equation and get 7

1.2m=8.4 inverse operation
Answers
Answer:
m = 7
Step-by-step explanation:
1.2m = 8.4
m is being multiplied by 1.2
to get m alone, we do the inverse operation to multiplication which is division.
Divide both sides by 1.2
1.2m/1.2 = 8.4/1.2
m = 7
Answer:
m=7
Step-by-step explanation:
8.4/1.2=7
2(4x - 2) = 8(x - 7)
Answers
Answer:
no solution
Step-by-step explanation:
2(4x - 2) = 8(x - 7)
8x - 4 = 8x - 56
0x = -52
no solution
Answer:
2(4x-2) = 8(x-7)
Distribute on both sides
2(4x)-2(2) = 8(x)-(7)(8)
Simplify
8x - 4 = 8x - 56
Subtract 8x from both sides to balance the equation.
-4 = -56
This is not equal.
Therefore the answer is no solution

Which equation represents f (x)?
O A f(x) = 2.5x + 2
O B. f (x) = 2x + 2.5
O c f(x) = (2.5 + 2)x
OD. f (x) = (2.5 - 2)x

Step-by-step explanation:
Linear function:
A linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the value that y changes by when x increases by 1, and b is the flat fee.
A bowling alley has a one-time charge of $2.50 to rent a pair of shoes and a charge of $2.00 for each game bowled.
This means that [tex]m = 2, b = 2.50[/tex]

Just took the test for plato and Edmentum users only
The estimated value of the expression is π which is approximately equal to the number 3.14.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The expression is given below.

The value of the expression is 3.14.

For the given hypothesis test, determine the probability of a Type II error or the power, as specified. A hypothesis test is to be performed to determine whether the mean waiting time during peak hours for customers in a grocery store has increased from the previous mean waiting time of 8.3 minutes. Preliminary data analyses indicate that it is reasonable to apply a -test. The hypotheses are H 0: μ = 8.3 H1: >8.3 The population standard deviation is 3.8 minutes. The sample size is 50. The significance level is 0.05. Find the probability of a Type II error if in fact the mean waiting timeu, is 9.8 minutes. A. 0.125 B. 0.05 C. 0.875 D. 0.95
Answers
Answer:
the probability of a Type II error if in fact the mean waiting time u, is 9.8 minutes is 0.1251
Option A) is the correct answer.
Step-by-step explanation:
Given the data in the question;
we know that a type 11 error occur when a null hypothesis is false and we fail to reject it.
as in it in the question;
obtained mean is 9.8 which is obviously not equal to 8.3
But still we fail to reject the null hypothesis says mean is 8.3
Hence we have to find the probability of type 11 error
given that; it is right tailed and o.5, it corresponds to 1.645
so
z is equal to 1.645
z = (x-μ)/[tex]\frac{S}{\sqrt{n} }[/tex]
where our standard deviation s = 3.8
sample size n = 50
mean μ = 8.3
we substitute
1.645 = (x - 8.3)/[tex]\frac{3.8}{\sqrt{50} }[/tex]
1.645 = (x - 8.3) / 0.5374
0.884023 = x - 8.3
x = 0.884023 + 8.3
x = 9.18402
so, by general rule we will fail to reject the null hypothesis when we will get the z value less than 1.645
As we reject the null hypothesis for right tailed test when the obtained test statistics is greater than the critical value
so, we will fail to reject the null hypothesis as long as we get the sample mean less than 9.18402
Now, for mean 9.8 and standard deviation 3.8 and sample size 50
Z = (9.18402 - 9.8)/[tex]\frac{3.8}{\sqrt{50} }[/tex]
Z = -0.61598 / 0.5374
Z = - 1.1462 ≈ - 1.15
from the z-score table;
P(z<-1.15) = 0.1251
Therefore, the probability of a Type II error if in fact the mean waiting time u, is 9.8 minutes is 0.1251
Option A) is the correct answer.
