I really need help<br> Solve for x

MakcuM [25]

$\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}$

1. Both are corresponding angles, hence they both are equal, so,

$44x + 2 = 45x \\ = > 2 = 45x - 44x \\ = > 2 = x \\ = > x = 2$

Ans. C) 2

2. They both are in interior corressponding, hence their sum is equal to 180°, so,

$10x + 6 + 104 = 180 \\ = > 10x + 110 = 180 \\ = > 10x = 180 - 110 \\ = > 10x = 70 \\ = > x = \frac{70}{10} \\ = > x = 7$

Ans. D) 7

3. They both are in interior corressponding, hence their sum is equal to 180°, so,

$x + 75 + x + 125 = 180 \\ = > 2x + 200 = 180 \\ = > 2x = 180 - 200 \\ = > 2 x = - 20 \\ = > x = \frac{ - 20}{2} \\ = > x = - 10$

Ans. A) -10

4. Both are corresponding angles, hence they both are equal, so,

$12x + 3 = 11x + 9 \\ = > 12x - 11x = 9 - 3 \\ = > x = 6$

Ans. A) 6

joja [24]

Answer:

0.86

Step-by-step explanation:

The z-score we need to make the comparison is given by

$\bf z=\frac{-2.05-(-2)}{\sigma/\sqrt{n}}$

where

$\bf \sigma$ = the standard deviation established in the study

n = the sample size

$\bf z=\frac{-2.05-(-2)}{0.3/\sqrt{42}}=-1.0801$

and for the Normal distribution N(0,1) we want to find

By using a spreadsheet or the table attached, we find that

P(X > -1.0801) = 0.86

(See picture attached)
