Answer:
135
Step-by-step explanation:
1 1/2 * 90=135
Answer:
x=-4
Step-by-step explanation:
The given equation is

Subtract 3 from both sides.


Divide both sides by -2.


If |x|=a, then x=a or x=-a.

Case 1: 
Subtract 1.5 from both sides.


Divide both sides by 0.5.

Case 2: 
Subtract 1.5 from both sides.


Divide both sides by 0.5.

Therefore, one solution is x=-2 and other solution is x=-4.
Use the slope formula

and plug in the values for x and y.
The answere to your question is $31 because 2 times 8 is 16 and 3 times 5 is 15 so if 15 plus 15 is 30 but sense it is 16 instead of 15 it is $31.
Answer:
Step-by-step explanation:
The hypothesis is written as follows
For the null hypothesis,
µd ≤ 10
For the alternative hypothesis,
µ > 10
This is a right tailed test
Since no population standard deviation is given, the distribution is a student's t.
Since n = 97
Degrees of freedom, df = n - 1 = 97 - 1 = 96
t = (x - µ)/(s/√n)
Where
x = sample mean = 8.9
µ = population mean = 10
s = samples standard deviation = 3.6
t = (8.9 - 10)/(3.6/√97) = - 3
We would determine the p value using the t test calculator. It becomes
p = 0.00172
Since alpha, 0.01 > than the p value, 0.00172, then we would reject the null hypothesis. Therefore, At a 1% level of significance, there is enough evidence that the data do not support the vendor’s claim.
