Answer:
w-9
Step-by-step explanation:
Plug in w = 9 to each equation
9+5=14

Answer:
3 3/4 yards of material
Step-by-step explanation:
Mandy was making 6 pillows, to give to her family. She needed 5/8 of a yard of material for each pillow. How many yards of material does she need?
From the above question:
1 pillow = 5/8 yard
6 pillows = x yards
Cross Multiply
1 pillow × x yards = 6 pillows × 5/8 yards
x yards = 6 pillows × 5/8 yards/1 pillow
x yards = 3 3/4 yards of material
Therefore, she needs 3 3/4 yards of material to make 6 pillows.

Step-by-step explanation:
Answer:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:
c). Reject H0 if test statistic is greater than 1.895.
Step-by-step explanation:
The system of hypothesis for this case are:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
The degrees of freedom are given by:
The p value for this case can be calculated from this probability:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:
c). Reject H0 if test statistic is greater than 1.895.
