Two shooters, Rodney and Philip, practice at a shooting range. They fire 100 rounds each at separate targets. The targets are marked with circles and each bullet hitting a particular circle gets them a particular number of points. 60 rounds are selected at random. The sample mean scores of Rodney and Philip are 8 and 10, respectively. And, their variances are 0.25 and 0.50, respectively The standard error of the difference between their mean scores is ______________ (Round your answer to two decimal places.) The 95% confidence interval for the difference between the mean scores Rodney and Philip is ________ _____________: (Enter a minus sign if your answer is negative. Round your answer to two decimal places.)

Answer:

A) SE = 0.1118

B) 95% Confidence interval is;

-2.22 < μ1 - μ2 < -1.78

Step-by-step explanation:

We are given;

Sample size; n = 60

Sample mean 1; x1 = 8

Sample mean 2; x2 = 10

Variance 1; v1 = 0.25

Variance 2; V2 = 0.5

Now,

Standard deviation is given by the formula ;

σ = √variance

Thus;

σ1 = √0.25

σ1 = 0.5

σ2 = √0.5

σ2 = 0.7071

Formula for standard error of mean is;

SE = σ/√n

Thus;

SE1 = 0.5/√60

SE1 = 0.06455

SE2 = 0.7071/√60

SE2 = 0.0913

The standard error of the difference between their mean scores would be;

SE = √[(SE1)² + (SE2)²]

SE = √(0.06455² + 0.0913²)

SE = 0.1118

Formula for 95% confidence interval is;

(x1 - x2) - ((Z_α/2) × SE) < μ1 - μ2 < (x1 - x2) + ((Z_α/2) × SE)

Where Z_α/2 is the critical value. At confidence interval of 95%, we have a critical value of 1.96 from tables.

Thus, plugging in the relevant values, we have;

(8 - 10) - (1.96 × 0.1118) < μ1 - μ2 < (8 - 10) + (1.96 × 0.1118)

-2.22 < μ1 - μ2 < -1.78

The density of a certain material is such that it weighs 5 kilograms for every 8.5 fluid

ounces of volume. Express this density in ounces per liter. Round your answer to the

nearest whole number.

**Answer:**

701 ounces per liter

**Step-by-step explanation:**

it's from delta math

The required **density **in **ounces **per liter is 140 **onces **per liter.

The density of a certain material is such that it weighs 5 kilograms for every 8.5 fluid ounces of volume.

To determine density in ounces per liter.

**Volume **is defined as the **ratio **of the **mass **of an object to its density.

As given that, t weighs 5 kilograms for every 8.5 fluid ounces of volume.

1 KG = 7.0474 ounces

5kg = 35.247

8.5 fluid of ounces = 0.251 liter

Density is given as,

= mass / volume

= 35.274 / 0.251

= 140 ounces per liter.

Thus, the required **density **in **ounces **per **liter **is s140 ounces per liter.

Solve and show the steps to the picture attached

**Answer:**

The image of point (2, 4) after transformation is **(-2, 13) ⇒ D**

**Step-by-step explanation:**

Let us revise some transformation

Translation right-left OR up-down

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h) ⇒ add x-coordinate of every point by hIf the function f(x) translatedA vertical stretching and a vertical compression (or shrinking)

IfLet us use these rules to solve the question.

∵ Point (2, 4) lies on y = x²

∵ The image of y = x² is y = 3(x + 4)²+1

→ The rules of transformation is y = m(x + h)² + k

∵ **m** is the scale factor of a **vertical stretched**

∵ **m = 3**

→ By using the **5th rule** above

∴ The y-coordinate of point (2, 4) should multiply by 3

∴ The image of the point is (2, 4 × 3) = **(2, 12)**

∵ h is the **horizontal translation to the left**

∵ **h = 4 **

→ By using the **2nd rule** above

∴ The x-coordinate of point (2, 12) should subtract by 4

∴ The image of the point is (2 - 4, 12) = **(-2, 12)**

∵ k is the **vertical translation up**

∵ **k = 1**

→ By using the **3rd rule** above

∴ The y-coordinate of point (-2, 12) should add by 1

∴ The image of the point is (-2, 12 + 1) = **(-2, 13)**

∴ **The image of point (2, 4) after transformation is (-2, 13)**

In a group of 80 people, 50 can speak Nepali, 45 can speak English and 7 of them do not

speak both languages.

a) Find the number of people who speak both languages.

b) Also illustrate the above information in Venn diagram.

**Answer:**

Universal set is 80

Number of people that speak Nepali is 50

Number of people that speak English is 45

Number of people that do not speak both is 7

a. Number of people that speak both languages is 22

b. As above

**Step-by-step explanation:**

a. Let make number of people that speak both languages x

To get x

(50-x) + (45-x) + x + 7 = 80

(50-x) + (45-x) + x = 80 - 7

(50-x) + (45-x) + x = 73

Open bracket

50-x+45-x+x= 73

50+45-2x+x = 73

95 - x = 73

-x = 73 - 95

-x = -22

x = 22

Therefore, number of people that speak both languages is 22

b. To get venn diagram

Number of people that speak Nepali is 50 - 22 = 28

Number of people that speak English is 45 - 22 = 23

Therefore, total = 28+23+22+7 = 80

1. Refer to the equation 3x − 5y = 15. (a) Create a table of values for at least 4 points. Show your work on how you found the values for each coordinate pair, and validated the points were on the line. Work for Point 1 Work for Point 2 Work for Point 3 Work for Point 4

**Answer:**

We have the equation:

3x - 5y = 15

a) We want to create a table with at least 4 points.

To do this, first, let's write the equation as a function: We must isolate one of the variables. Let's isolate y.

5y = 3x - 15

y = (3/5)*x - 3.

Then we have a linear equation.

Now, we can input different values of x, and see what value takes y in each case, then in this way we can be sure that the points will be on the line.

**x = 0.**

y = (3/5)*0 - 3

y = -3

Then we have the point (0, -3).

**x = 1.**

y = (3/5)*1 - 3 = 3/5 - 15/5 = -12/5

y = -12/5

Then we have the point (1, -12/5)

**x = 5**

y = (3/5)*5 - 3 = 3 - 3 = 0

y = 0

then we have the point (5, 0)

**x = 10**

y = (3/5)*10 - 3 = 6 - 3 = 3

y = 3

Then we have the point (10, 3).

Now we can create the table

she drank 14 ounces of her water, she has 28 ounces left, just divide 42 by 3

**Answer:**

1)14oz

2)28oz

**Step-by-step explanation:**

1) To find the amount of water is left in the bottle you want to substract 1/3 so the first thing you want to do is find what 1/3 of 42 is. So do this: (This is also 42/3)

42*1/3=14

So we now know that 14 is 1/3 of 45 which is the first answer. To find the second answer you want to substract 14 from 42 which is 28.

So that means she has 28 oz of water left when she gets there.

4. Gabby ate 25 % of a whole pepperoni pizza.

Lebron ate 1/8 of the pizza.

What fraction of the pizza was left for Mohamed to eat?

**Answer:**

**There is 5/8 left for Mohamed to eat.**

**Step-by-step explanation:**

Let's put everything into fractions of 1/8. knowing that 25% is 1/4 or 2/8, 1/8 + 2/8= 3/8. and to find the answer, you need to subtract 3/8 from 8/8 or 1.

As a result, 5/8.

**1/8 = 12.5%**

**12.5% + 25% = 37.5%**

**We need to know how much is left.**

**37.5% is gone, so 100% - 37.5% = 62.5%**

**62.5% is left for Mohamed to eat.**

**62.5% = 5/8.**

**5/8 of a pizza is left for mohamed to eat.**
