Pls do it for me it
anzhelika [568]

Answer:

t=75 3x=75 and y=30

Step-by-step explanation:

t and 3x are equivalent because the sides are the same lengths. knowing that you can subtract 105 from 180 getting 75 for t, knowing that t and 3x are equivalent you also get the answer for 3x witch is 75. the sum of all the angles is 180 and adding 3x and t you get 150, subtracting 150 from 180 you get 30 the answer to degree y.

Given N(14, 3)
bearhunter [10]

Answer:

Step-by-step explanation:

we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = variable

µ = mean output

σ = standard deviation

From the information given,

µ = 14

σ = 3

1) P(x < 20)

For x = 20,

z = (20 - 14)/3 = 2

From the normal distribution table, the corresponding probability value is 0.98

% = 0.98 × 100 = 98%

2) P(11 ≤ x ≤ 17)

For x = 11,

z = (11 - 14)/3 = - 1

From the normal distribution table, the corresponding probability value is 0.16

For x = 17,

z = (17 - 14)/3 = 1

From the normal distribution table, the corresponding probability value is 0.84

P(11 ≤ x ≤ 17) = 0.84 - 0.16 = 0.68

% = 0.68 × 100 = 68%

3) P(x > 14) = 1 - P(x ≤ 14)

For x = 14,

z = (14 - 14)/3 = 0

From the normal distribution table, the corresponding probability value is 0.5

P(x > 14) = 1 - 0.5 = 0.5

% = 0.5 × 100 = 50%

4) P(5 ≤ x ≤ 17)

For x = 5,

z = (5 - 14)/3 = - 3

From the normal distribution table, the corresponding probability value is 0.00135

For x = 17,

z = (17 - 14)/3 = 1

From the normal distribution table, the corresponding probability value is 0.84

P(5 ≤ x ≤ 17) = 0.84 - 0.00135 = 0.839

% = 0.839 × 100 = 83.9%

Which expression is equivalent to 7- 3x +2?​
Colt1911 [192]

Answer: 9-3x

Step-by-step explanation:

You add like terms

don't look at the 3x for now

positive 7 + positive 2 = 9

there is a negative sign next to 3x

9 goes first so

9 - 3x

Write and solve an equation to find the number n. Six times the sum of a number and 15 is -42.
nata0808 [166]

Answer:

8

Step-by-step explanation:

6*(n + 15) = -42

Divide both sides by 6

6*(n - 15)/6 = -42/6

n - 15 = -7

n = -7 + 15

n = 8
