An equation is shown below: 6(2x - 11) 15 = 21 Write the steps you will use to solve the equation and explain each step.
kolbaska11 [484]

Answer:

x=6

Step-by-step explanation:

6(2x -11) 15 =21

6 × 2x = 12x

6 × -11 = -66

12x -66 + 15 = 21

-66 + 15 = -51

12x -51 = 21

-51 + 51 = 0

21 + 51 = 72

12x = 72

12x ÷ 2 = 0

72 ÷ 12 = 6

x = 6

Xavier left his house at time zero and
Lady_Fox [76]

Answer:

Graph the points, (2,18) (7, 24) and (16, 0)

Step-by-step explanation:

Going to the store takes 2 minutes for 18 blocks, which is the first point

He stays at the store for 2 minutes then takes 3 minutes to get to the bank which is 6 blocks away, add the time together and blocks, and you get the second point

He stopped at the bank for 3 minutes and the drove back home. It takes him 6 minutes to get back home, (24/6), add all the minutes together and you get 16.

(This is assuming the graph is y for blocks and x for minutes)

When conducting a two-tailed z test with a = 0.01, the test value was computed to be 2.07. The decision would be to reject or to
vekshin1
You reject the Null Hypothesis only if the p-value is less than alpha.
p < 0.01

To find the p-value, you need to look up test value 2.07 in a standard normal table. The p-value is probability that Z > 2.07. For a two-tailed test, you include both positive and negative cases. |Z| > 2.07.

When you look up 2.07 you get about 0.98.
This means there is about 2% chance Z > 2.07 or 4% chance |Z| > 2.07.

For the two-tailed test we use p = 0.04
.04 > .01
Therefore we do Not reject the Null Hypothesis.
