Which event has theoretical probability of exactly 1/5 select three options

Answers

Answer 1

The spinner is divided into 10 equal sections.

Which event has theoretical probability of exactly 1/5? Select three options.

A) spinning a number less than 3

B) spinning a 4 or 5

C) spinning an odd number

D) spinning a number greater than 8

E) spinning a number less than 8

Answer:

Options A, B & D are correct

Step-by-step explanation:

From the image attached, we can see that the total number on the spinner is 10.

Now, we want to find which event has theoretical probability of exactly 1/5

Option A: spinning a number less than 3 means we get 1 or 2 which is 2 numbers.

Thus; probability = 2/10 = 1/5.

This option is true

Option B: spinning a 4 or 5 means 2 numbers.

Thus; probability = 2/10 = 1/5.

This option is true

Option C: Odd numbers in the spin are 1,3,5,7,9. This is a total of 5 numbers.

Thus, probability = 5/10 = 1/2

This option is wrong.

Option D: Numbers greater that 8 are 9 & 10. That's 2 numbers.

Thus, probability = 2/10 = 1/5

This option is correct

Option E: numbers less than 8 are;

1,2,3,4,5,6,7. That's a total of 7 numbers.

Probability = 7/10

Thus, this option is wrong.

An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California. Suppose that the mean income is found to be $22.4 for a random sample of 2128 people. Assume the population standard deviation is known to be $9.3. Construct the 98% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place.

Answers

Answer:

[21.9, 22.9] in thousands of dollars

Step-by-step explanation:

The formula for Confidence Interval

= Mean ± z score × standard deviation/√n

Mean = $22.4

Standard deviation = $9.3

n = 2128

z score of 98% confidence interval = 2.326

Confidence Interval = 22.4 ± 2.326 × 9.3/√2128

= 22.4 ± 0.469

Confidence Interval =

22.4 - 0.469

= 21.931

≈ 21.9 in thousand of dollars

22.4 + 0.469

= 22.869

≈ 22.9 in thousands of dollars

Hence, the 98% confidence interval =

[21.9, 22.9] in thousands of dollars

Answer:

x=5

Step-by-step explanation:

I was working on this problem also.

Maybe my version will help, too.

You need to sketch f given the information you have.

f'(x) is approximately a a cubic polynomial which means f will look like a quartic (think W)

f slopes down (negative slope) to x=2 and then slopes down again...this is a horizontal tangent.

f then slopes down to to x=5 where is has a minimum and then slopes up.

In parallelogram WXYZ, what are the coordinates of the point of intersection of WY and ZX?

Point of Intersection = ____ ____

Answers

Answer:

Point of intersection of WY and ZX is (3.5, 3.5).

Step-by-step explanation:

Since, diagonals of a parallelogram bisect each other,

Point of intersection of the diagonals will be midpoint of each diagonal.

By this property, midpoint (x, y) of the segment joining W(-2, 6) and Y(9, 1) will be,

[tex]x=\frac{x_1+x_2}{2}[/tex]

x = [tex]\frac{-2+9}{2}[/tex] = 3.5

Similarly, y-coordinate of the midpoint will be,

y = [tex]\frac{y_1+y_2}{2}[/tex]

y = [tex]\frac{6+1}{2}[/tex] = 3.5

Therefore, point of intersection of the diagonals of the given parallelogram will be (3.5, 3.5).

Answers

Answer:

x = 30

Step-by-step explanation:

Since this is a right triangle,

90 = (x + 20) + (x + 10)

90 = x + x + 20 + 10

90 = 2x + 30

90 - 30 = 2x

60 = 2x

60/2 = 2x/2

30 = x

Check:

x + 20

30 + 20 = 50

x + 10

30 + 10 = 40

50 + 40 = 90

If three servings of ice cream has 24g of fat, how many milligrams of fat does one serving have?

Answers

Answer:

600

Step-by-step explanation:

24 by 3 times 100

The number of milligrams of fat that one serving has is 8000 milligrams.

Firstly, it should be noted that

1000mg = 1 gram.

Since three servings of ice cream has 24g of fat, therefore, the fa that will be contained in each will be:

= 24/3

= 8g

Therefore, we'll convert 8 grams to milligrams and this will be:

= 8 × 1000

= 8000 milligrams.

Therefore, a serving has 8000 milligrams.

64 is the measure of angle A.

Step-by-step explanation:

===================================================================

The triangle is an isosceles triangle, so when you use the supplementary theorem for angle BCA and 116, you get 64. And since the base pairs are equal, angle A is 64.

===================================================================

Answer:

m∠A = 64°

Step-by-step explanation:

If AB = BC , then ∠CAB ≅ ∠ACB

m∠ACB = 180° - 116° = 64° ⇒ m∠A = 64°

[tex] \frac{1}{2} x = 60 \\ [/tex]

Multiply sides by 2

[tex]2 \times \frac{1}{2} x = 2 \times 60 \\ [/tex]
