Help me on this math problem please!! DUE TONIGHT!! Write an equation!

Answers

Answer 1

Answer:

(3x+8)°+(x+4)° = 180,

x=42

Step-by-step explanation:

They are linear pairs, so the two angles are supplementary or add up to 180°.

1. Format the equation (3x+8)°+(x+4)° = 180

2. Simplify like terms 4x + 12 = 180

3. Subtract 12 on both sides, 4x=168

4. Divide 4 on both sides, x=42

5. Answer is x=42

Answer 2

3x+8=x+4
-x -x
2x+8=4
-4 -4
2x=4
x=2

Events A and B are independent. Let P(B)=0.4 and P(A and B)=0.13. Find P(A). Write your answer as a decimal rounded to the nearest thousandth.

Answers

The probability value represented by P(A) is 0.325

How to determine the probability value P(A)?

The given parameters are:

P(B) = 0.4

P(A and B) = 0.13

Given that the events A and B are independent, we have:

P(A and B) = P(A) * P(B)

So, we have:

0.13 = P(A) * 0.4

Divide both sides by 0.4

P(A) = 0.325

Hence, the probability value of P(A) is 0.325

C. 518.00 LBS

D. 296.00 LBS

I WILL GIVE BRAINLELIST

Answers

Answer:

D. 296.00 LBS

Step-by-step explanation:

We convert both heights to inches.

1 ft = 12 in.

5 ft 3 in = 5 × 12 in. + 3 in. = 63 in.

6 ft = 6 × 12 in. = 72 in.

[tex] \dfrac{63~in.}{259~lb} = \dfrac{72~in.}{x} [/tex]

[tex] \dfrac{63x}{259} = 72~lb [/tex]

[tex] x = \dfrac{259 \times 72~lb}{63} [/tex]

[tex] x = 296~lb [/tex]

Answer: D. 296.00 LBS

If data is normally distributed and has μ = 90 and o-10, what is the z-score for a data value of 75?

Answers

Answer:

The z-score for this data is -1.5

Step-by-step explanation:

Step 1: For the specified distribution and data point,

μ = 90, σ = 10, and x = 75 (given)

Step 2: We now apply the z-score formula:

z = x − μ / σ

z = 75 - 90 / 10

z = - 15 / 10

z = -1.5

We can take it a step further:

A z-score table shows the percentage of values (usually a decimal figure) to the left of a given z-score on a standard normal distribution

percentage of value = 0.0668

The diameter of a circle is 26 cm. Find its area to the nearest whole number.

Answers

area= pi x r^2
= pi x 13^2
=pi x 169
= 530.929
= to the nearest whole number 531

Answer:

531

Step-by-step explanation:

The area of a circle can be determined by the equation: A = πr².

The "r-value" represents the radius, which is half of the diameter. Since the diameter is in cm, the area will have the unit cm².

d = diameter r = radius π = 3.14..... A = area

d / 2 = r

26 / 2 = r

13 cm = r

A = πr²

A = π(13)²

A = 169π

A = 530.929.... cm²

A = 531 cm²

As you can see, the radius was determined to be 13 cm. When you plug that value into the area equation, you get 530.9 cm². Rounding to the nearest whole number would bump the 0 to 1, making the final answer 531 cm².
