The figure shows two triangles on the coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis an

d from positive 6 to negative 6 on the y-axis. A triangle ABC is shown with vertex A on ordered pair 4, 1, vertex B on ordered pair 3, 1, and vertex C on ordered pair 4, 4. Another triangle A prime B prime C prime is shown with vertex A prime on ordered pair negative 4, 4, vertex B prime on ordered pair negative 3, 4, and vertex C prime on ordered pair negative 3, 1. What set of transformations is performed on triangle ABC to form triangle A′B′C′?

Space shuttle Challengerexploded because of O-ring failure shortly after it was launched. O-ring damage and temperature at time
arlik [135]

Answer:

The mean launch temperature for flights with O-ring damage is significantly lesser than Flights with No O-ring

Step-by-step explanation:

Let

Null hypothesis : H0 : μ1 ≥ μ2

Alternate hypothesis : Ha : μ1 < μ2

next calculate the test statistic

t = -2.312

calculate the P-value

p-value = T.DIST ( t ,df )  (  excel function )

            = 0.0270

Given that P-value ( 0.020 ) < level of significance ( 0.05 ) we will not fail to reject the null hypothesis

Attached below is the detailed solution

Solve this equation <br> 3x-1/5-2/9x=124/5
Flauer [41]

Answer: x = 9

Step-by-step explanation:

1) Combine multiplied terms into a single fraction

2) Find a common denominator

3) Combine fractions with common denominator

4) Multiply from left to right (PEMDAS)

5) Multiply all terms by the same value to eliminate fraction denominators

6) Cancel multiplied terms that are in the denominator

7) Multiply again

8) Add _ to both sides

9)  Divide both sides by the same factor getting 125x/125 = 1125/125

10) Simplify, x = 9
