used to approximate the sampling distribution?

For Which Sample Size (n) And Sample Proportion (p) Can A Normal Curve Beused To Approximate The Sampling

Answers

Answer 1

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Option a:

[tex]np = 35*0.8 = 28 > 10[/tex]

[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]

So option a cannot be used.

Option b:

[tex]np = 65*0.9 = 58.5 > 10[/tex]

[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]

So option b cannot be used.

Option c:

[tex]np = 65*0.8 = 52 > 10[/tex]

[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]

So option c can be used, and is the answer

Option d:

[tex]np = 35*0.9 = 31.5 > 10[/tex]

[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]

So option d cannot be used.

The answer is given by option c.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Boy's age = x

Girl's age:

y = x + 3

Now,

x (x + 3) = 54

x² + 3x - 54 = 0

x² + (9 - 6) - 54 = 0

x² + 9x - 6x - 54 = 0

x(x + 9) - 6(x + 9) = 0

x - 6 = 0

x = 6

x + 9 = 0

x = -9 ( cannot be negative)

Now,

x = 9

Boy's age = 9

Girl's age = 9 + 3 = 12

Thus,

The boy's age and the girl's ages are 9 and 12.

Lets us start with finding the inner angles of the triangle. The bottom right angle shall be 70 degrees as it is opposite. The 100 degrees shall add together to make 200. 360-200 = 160. 160 / 2 = 80. So, Now we know bottom left angle (80) and bottom right (70). 80 + 70 = 150. In a triangle, angles add to 180 so 180 - 150 = 30. 30 = 2x which means that x = 15

A gorilla needs to eat at least 40 pounds of food each day. The zoo feeds the gorilla using canisters that contain 4 pounds of food. The gorilla
has already consumed 28 pounds of food. How many more canisters z of food does the gorilla need to ear? Write your answer as an inequality.

Answers

4z+ 28 ≥ 40

At least would be present as using ≥ or greater than or equal to symbol.

So far the gorilla has consumed 28 pounds of food and each can contains 4 pounds of food.

So: 28 pounds of food/ 4 pounds of food per can= 7 cans consumed

40 pounds needed - 28 pounds consumed= 12 pounds left

12 lbs/ 4 lbs per can= 3 cans left for the gorilla to exceed its goal

Solve the proportion.
20/13 = 60/d
d=

Answers

Answer:

[tex]d = 39[/tex]

Step-by-step explanation:

1) Multiply both sides by d.

[tex] \frac{20}{13} d = 60[/tex]

2) Simplify 20/13d to 20d/13.

[tex] \frac{20d}{13} = 60[/tex]

3) Multiply both sides by 13.

[tex]20d = 60 \times 13[/tex]

4) Simplify 60 × 13 to 780.

[tex]20d = 780[/tex]

5) Divide both sides by 20.

[tex]d = \frac{780}{20} [/tex]

6) Simplify 780/20 to 39.

[tex]d = 39[/tex]

Therefor, the answer is d = 39.
