Answer 1

The z-score is approximately 96.51. None of the given options match the calculated z-score.

The z-score can be calculated using the formula z = (x - μ) / σ, where x is the observed value, μ is the population mean, and σ is the population standard deviation.

In this problem, we are given that in the population, 10% of people have blue eye color. This means that the population proportion of people with blue eyes is 0.10 (or 10%).

Lane observed a sample of 35 people and found that 5 of them had blue eyes. We want to calculate the z-score to determine how many standard deviations away Lane's observation is from the expected population proportion.

First, we need to calculate the population standard deviation (σ) using the population proportion (p) and the sample size (n). Since the population standard deviation is the square root of the population variance, we can use the formula:

σ = √(p * (1 - p) / n)

In this case, p = 0.10 and n = 35, so we can substitute these values into the formula:

σ = √(0.10 * (1 - 0.10) / 35)

≈ √(0.09 / 35)

≈ √0.00257

≈ 0.0507

Now, we can calculate the z-score using the observed value (x), which is 5, the population mean (μ), which is the same as the population proportion (p), and the population standard deviation (σ):

z = (x - μ) / σ

= (5 - 0.10) / 0.0507

= 4.90 / 0.0507

≈ 96.51

Therefore, the z-score is approximately 96.51.

It seems that the provided options for the z-score are not accurate. None of the given options match the calculated z-score.

Step-by-step explanation:

To solve you must isolate the variable. Do this by using the properties of equality to subtract and divide numbers from both sides of the equation. First, subtract 8x to move all x terms to the right side.

-48=12x

Then, divide both sides by 12

So I've noticed a lot of people have been struggling on equations like these : 8 + ( 2 * 7 )
and I'll be explaining an easy way on how to solve it.

So basically 2 * 7 = 14, now we just have to add 8 + 14 which equals 22.
The parenthesis is the equation you have to solve to get your answer and then you just have to either add, subtract, multiply or divide to find your answer.

What are integers?

Integers are whole numbers. It is a number without a fraction or decimal component. Integers can either be positive, negative or zero.

Consecutive integers are whole numbers that follow each other on the number line. For example, 1, 2, 3, 4 .... are consecutive integers.

How to determine the product of the 500 consecutive integers

If the sum of the 500 consecutive integers is equal to 250, it means that the consecutive integers would include negative numbers, zero and positive numbers. If the consecutive integers include zero, the product of the consecutive integers would be equal to zero.

Answers

Explanation:

This might not be how you are supposed to do it but,

We can see the two triangles are similar because AA similarity.

We know that the sides are proportional so we can make:

[tex]\frac{x+2}{x}=\frac{4}{3x-1}[/tex]

We get,

[tex]3x^2+5x-2=4x\\3x^2+x-2\\(3x-2)(x+1)=0\\x=2/3, x=-1[/tex]

Because sides can't be negative, x = 2/3

Answer:

x=2/3 = 0.7

Step-by-step explanation:

X+2/x = 4/3x-1

=(X+2)(3x-1)=4x

(x+2)(3x-1)-4x=0

3x²-x+6x-2-4x=0

3x²+x-2=0

3x²+3x-2x-2=0

3x(x+1)-2(x+1)

(x+1)(3x-2)=0

x+1=0

3x-2=0

x=-1 or 2/3

x=2/3 = 0.7

Step-by-step explanation:

∠x, ∠BAC, and ∠CAF form a straight line.

*Sum of angles that are formed on a straight line is equal to 180°.*

[tex]\tt \angle x+\angle BAC+\angle CAF=180^{\circ}[/tex]

[tex]\tt x+\angle BAC+\angle CAF=180^{\circ}[/tex]

[tex]\tt x+80^{\circ}+\angle 60^{\circ}=180^{\circ}[/tex]

Add, 80°+60°=140°

[tex]\tt x+140^{\circ}=180^{\circ}[/tex]

Subtract 140 from both sides:
