A study regarding the relationship between age and the amount of pressure sales personnel feel in relation to their jobs reveale

djyliett [7]

Answer and Step-by-step explanation:

a) H o : there is no relation between job pressure and age

H 1: there is a relation between job pressure and age

b) See file attached.

c) Test statistic: For the given categorical data, we apply the x² — test Test statistic is 2.19

d) The test statistic value x² = 2.19 < 16.81, we accept the null hypothesis. Therefore, we conclude that there is no relationship between job pressure and age.

Find the scale factor of the dilation shown A. 1/2 B. 3/2 C. 2 D. 2/3

AleksandrR [38]

Answer:

B

Step-by-step explanation:

To go from 6 to 9 you'd first have to divide 6 by 2 and the multiply by 3,

so $\frac{1}{2}$ x 3 = $\frac{3}{2}$

Hello everyone I need help with this worksheet it's ten problems answer the ones you know for me please it's homework.

Fed [463]

Answer:

1. Slope = -4/5

2. Slope = 2/3

3. Slope = 0

4. Slope = 3/-4

5. Slope = 7/-12

6. Slope = 1/2

7. Slope = -2/0 --> Undefined

8. Slope = 3/-2

9. Slope = 5/-4

10. Slope = 4/3

Step-by-step explanation:

Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:

10-2/1-11 = 8/-10 = -4/5

What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?

musickatia [10]

Answer:

$219456$

Step-by-step explanation:

It must end in $0,2,4,6,8$ (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).

The digit sum is $2+A+9+4+5+B=20+A+B$ .

We want to make $A$ as low as possible because it's a higher digit than $B$ .

If $A$ is as low as possible, we have that the sum is $20+0+7=27$ . Uh-oh. $B$ has to be even! So $A=0$ doesn't work.

If $A=1$ , we have that the sum is $20+1+6=27$ . Yay!

So, the answer is $\boxed{219456}$

Three cube-shaped boxes are stacked one above the other. The volumes of two of the boxes are 1,331 cubic meters each, and the vo

blsea [12.9K]

The volume of a box with dimensions x by x by x is $x^{3}$ .

So if we are given the volume V of a cube-shaped box, the side length of thit is $\sqrt[3]{V}$ .

So we calculate the cubic roots of the volumes we have, and we add their heights.

To calculate the cubic root of 729, we can factorize it, and group the perfect cubes together, as follows:

$\frac{729}{3}= \frac{600}{3} + \frac{120}{3} + \frac{9}{3}=200+40+3=243$

$\frac{243}{3}= \frac{240}{3}+ \frac{3}{3}=80+1=81$ , which we recognize as $3^{4}$

so $729=3*3* 3^{4}= 3^{6}= ( 3^{2} )^{3}= 9^{3}$

similarly 1,331 can be found to be $11^{3}$ .

Thus we have 2 boxes with side length equal to 11 m and one with side length equal to 9 m.

Answer: h= 11+11+9 = 31 (meters)
