**Answer:**

C. 5/2

**Step-by-step explanation:**

Two points that the graph passes through are (-5, -4) and (-3, 1). This tells us that the graph goes up 5 units at the same rate that it goes right 2 units. Since the slope of a graph is simply the movement of the y values over the movement of the x values, the slope of this graph is **5/2**,** **which is** option C**.

### Answers

**Answer:Option 2**

**Step-by-step explanation:**

Solve for x.

Enter the number that belongs in the green box

### Answers

**Answer:**

x = 45

**Step-by-step explanation:**

Because these are two congruent triangles inside of each other we can set up an equivalency ratio.

25/35 = x/65

Multiply both sides by 65 to get x alone

65 * 25/35 = x/65 * 65

(65 * 25)/35 = x1

1576/35 = x

x = 45

O A. Two standard deviations

O B. One standard deviation

C. It cannot be determined from the given information.

O D. Three standard deviations

### Answers

In a **normal distribution**, 95% of the data falls within two** standard deviations.**

**What is a normal distribution?**

The most typical distribution **function **for independent, randomly produced data is the **normal distribution**, commonly known as the **Gaussian distribution**. Every statistical report uses this well-known bell-shaped curve, from survey analysis and quality control to resource allocation.

Here,

We have to determine in a** normal distribution**, 95% of the data fall within how many **standard deviation**s of the **mean**.

We concluded that 95% of the data points will fall within two **standard deviation**s of the **mean**. 99.7% of the data points will fall within three **standard deviation**s of the **mean**.

Hence, In a **normal distribution**, 95% of the data falls within two** standard deviations.**

The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = (x – 8). What

is the slope-intercept form of the equation for this line?

O y = 1 x - 12

O y = -x-4

O y=+*+2

O y=x+6

### Answers

Answer: y = x/4 + 2

Y equals one fourth x plus two.

Step-by-step explanation:

There seems to be a typo on answer choice c.

Slope intercept form is y= mx + b

m is the slope. b is the y-intercept.

The y-intercept is given here in the coordinate (0,2) It is +2

Slope is rise/run.

Rise: Difference in given y-values is 4-2 = 2.

Run: Difference in x-values is 8-0=8.

So the slope is 2/8 = 1/4

The equation is y = 1/4 x + 2

Basic Computation: Finding Probabilities, let z be a random variable with a standard normal distribution. Find the indicated probability, and shade the corresponding area under the standard normal curve.

P(-1.20 = z = 2.64)

### Answers

**Answer:**

** 0.8808 **

**Step-by-step explanation:**

The objective is to calculate the probability of:

P(-1.20 ≤ z ≤ 2.64)

i.e. the probability that is the area between two z-values.

Thus;

P(-1.20 ≤ z ≤ 2.64) = P(z ≤ 2.64) - P( z ≤ 1.20)

From z table;

P(-1.20 ≤ z ≤ 2.64) = 0.9959 - 0.1151

P(-1.20 ≤ z ≤ 2.64) = **0.8808 **

We can see the shaded area under the standard normal curve from the image attached below.

The mean volume for a bottle of cologne is 4 ounces and the standard deviation is 0.22 ounces. A random sample of 121 bottles is taken. What is the probability of obtaining a sample mean within 0.04 ounces of the population mean?

a. 0.9545

b. 0.0363

c. 0.3085

d. 0.5000

### Answers

**Answer:**

The standard error of the mean is 0.02

**Step-by-step explanation:**

Here, we want to calculate the standard error of the mean.

Mathematically;

standard error of mean = SD/ √n

where SD is the standard deviation and n is the number of samples

From the question, SD = 0.22 and n = 121

Inserting this into the equation

Standard error of the mean = 0.22/√121

= 0.22/11 = 0.02

The **probability** of obtaining a **sample mean** is "* 0.9545*".

According to the question,

**Mean**,

[tex]\mu = 4[/tex]

**Standard deviation**,

[tex]\sigma = 0.22[/tex]

Random **sample**,

[tex]n = 121[/tex]

By **Central limit theorem**,

→ [tex]\bar {x} \sim (4, \frac{0.22}{\sqrt{121} } )[/tex]

[tex]= 0.2[/tex]

Now,

→ [tex]P(|\bar{x} - \mu| \ \alpha \ 0.04) = P(-0.04 \ \alpha \ \bar{x} - \mu \ \alpha \ 0.04)[/tex]

[tex]= P(\frac{-0.04}{0.02} \ \alpha \ z \ \alpha \ \frac{0.04}{0.02} )[/tex]

[tex]= P(-2 \ \alpha \ z \ \alpha \ 2)[/tex]

[tex]= 0.9545[/tex]

Thus the above response i.e., "**option a**" is appropriate.
