Answer:

The probability of getting 3 successive 1's from spinning the spinner 3 times = 0.027

Step-by-step explanation:

The spinner has 4 sides, 1,2,3 and 4

The probability of landing on a 1 = P(1) = 0.3

The probability of landing on a 2 = P(2) = It isn't given

The probability of landing on a 3 = P(3) = x

The probability of landing on a 4 = P(4) = 0.1

If Denzil spins the spinner 3 times, what is the probability of getting 3 successive 1's?

Noting that each spin is independent from one another, the probability of getting 3 successive 1's from spinning the spinner 3 times is given as

P(1) × P(1) × P(1) = 0.3 × 0.3 × 0.3 = 0.027

Hope this Helps!!!

Answer: 95% confidence interval = 20,000 ± 2.12 $\times$ $\frac{1500}{\sqrt{17} }$

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )

Step-by-step explanation:

Given :

Sample size(n) = 17

Sample mean = 20000

Sample standard deviation = 1,500

5% confidence

∴ $\frac{\alpha}{2}$ = 0.025

Degree of freedom ( $d_{f}$ ) = n-1 = 16

∵ Critical value at ( 0.025 , 16 ) = 2.12

∴ 95% confidence interval = mean ± $Z_{c}$ $\times$ $\frac{\sigma}{\sqrt{n} }$

Critical value at 95% confidence interval = 20,000 ± 2.12 $\times$ $\frac{1500}{\sqrt{17} }$

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )

What is the solution to the proportion?<br> 5/x = 2/16

mixas84 [53]

Answer:

I believe the answer is X=40

Step-by-step explanation:

cross multiply 5*16 = X * 2

Multiply 5*16

80= X*2

Add '-2x' to each side of the equation

80 + -2x = 2x + -2x

Combine like terms

80 + -2x = 0

Add '-80' to each side of the equation.

80 + -80 + -2x = 0 + -80

Combine like terms: 80 + -80 = 0

0 + -2x = 0 + -80

-2x = 0 + -80

Combine like terms: 0 + -80 = -80

-2x = -80

Divide each side by '-2'.

x = 40

Simplifying

x = 40

Hope this helped :)
