Answer:

x=5

y=7

z=6

Step-by-step explanation:

I know because Figure 1 the number is 9 and in figure 2 the number is 3 so it must of divided by 3.

4. In Problem 2, you were told that the durations of high school baseball games are approximately normally distributed with a me

gregori [183]

Answer:

It is more likely that a high school baseball game will last between 100 and 110 minutes or that a high school softball game will last between 100 and 110 minutes

Step-by-step explanation:

We are given the following information in the question:

Basket ball game:

Mean, μ = 105 minutes

Standard Deviation, σ = 11 minutes

Softball game:

Mean, μ = 95 minutes

Standard Deviation, σ = 11 minutes

We are given that the distribution of durations of high school baseball games is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(basketball game will last between 100 and 110 minutes)

$P(100 \leq x \leq 110) = P(\displaystyle\frac{100 - 105}{11} \leq z \leq \displaystyle\frac{110-105}{11}) = P(-0.454 \leq z \leq 0.454)\\\\= P(z \leq 0.454) - P(z < -0.454)\\= 0.675 - 0.325 = 0.35$

P(softball game will last between 100 and 110 minutes)

$P(100 \leq x \leq 110) = P(\displaystyle\frac{100 - 95}{11} \leq z \leq \displaystyle\frac{110-95}{11}) = P(0.454 \leq z \leq 1.363)\\\\= P(z \leq 1.363) - P(z < 0.454)\\= 0.914 - 0.675 = 0.239$

Since,

P(basketball game) > P(softball game)

It is more likely that a high school baseball game will last between 100 and 110 minutes or that a high school softball game will last between 100 and 110 minutes

It’s MATH who knows how to do this i’m down bad

AysviL [449]

Answer/Step-by-step explanation:

1. 7x + 2 = 5x + 22 (alternate interior angles are congruent)

Collect like terms

7x - 5x = -2 + 22

2x = 20

2x/2 = 20/2

x = 10

2. 13x - 6 = 10x + 24 (alternate interior angles are congruent)

Collect like terms

13x - 10x = 6 + 24

3x = 30

3x/3 = 30/3

x = 10

3. (12x + 26)° + 46° = 180° (same side interior angles are supplementary)

12x + 26 + 46 = 180

12x + 72 = 180

12x + 72 - 72 = 180 - 72

12x = 108

12x/12 = 108/12

x = 9

4. (5x + 5)° + 135° = 180° (same side interior angles are supplementary)

5x + 5 + 135 = 180

5x + 140 = 180

5x + 140 - 140 = 180 - 140

5x = 40

5x/5 = 40/5

x = 8
