Based on a study by Dr. P. Sorita Soni at Indiana University, assume that eye colors in the United States are distributed as follows: 40% brown, 35% blue, 12% green, 7% gray, 6% hazel. If three people are randomly selected, what is the probability that one will have brown eyes, one will have gray eyes, and one will have green eyes (with replacement)
Answer
0.00336
Step-by-step explanation:
Given :
P(Brown), P(Br) = 0.4
P(Blue) = P(b= 0.35
P(green,) = P(g) = 0.12
P(gray), P(Gr) = 0.07
If 3 individuals are selected, the probability that one has brown eye, 1 has Grey and one has green.
Since the probabilities are independent :
P(Br) * P(Gr) * P( g)
0.3 * 0.07 * 0.12
= 0.00336
Decide if the following statement is true or false. Explain why. It is possible to have a standard deviation of 445,000.
Answer:
TRUE
Step-by-step explanation:
Standard deviation is defined as the measure of spread. In other words, it shows and determines how spread out the numbers are, i.e. the amount of dispersion or variation of a given set of numbers.
The standard deviation ranges from zero to any number. So it is possible to have a standard deviation of number 445,000 because the standard deviation can be of any value greater than or equal to zero.
Using the standard deviation concept, it is found that since the standard deviation is always a positive value or zero, the statement is true.
What is the standard deviation of a data-set?The standard deviation is given by the square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values.It always assume a positive value or zero.Hence, considering that the standard deviation is always a positive value or zero, the statement is true.

An educational psychologist wishes to know the mean number of words a third grader can read per minute. She wants to make an estimate at the 85% level of confidence. For a sample of 295 third graders, the mean words per minute read was 26.9. Assume a population standard deviation of 2.7. Construct the confidence interval for the mean number of words a third grader can read per minute. Round your answers to one decimal place
Answer:
85% level of the confidence interval is
(26.337, 26.662)
Step-by-step explanation:
Explanation:-
Given the size of the sample 'n' = 295
Mean of the sample x⁻ = 26.5
The Standard deviation of the Population = 2.7
85% level of the confidence interval is determined by
[tex](x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })[/tex]
Critical value Z₀.₁₅ = 1.036
85% level of the confidence interval is determined by
[tex](x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })[/tex]
[tex](26.9 -1.036 \frac{2.7}{\sqrt{295} } , 26.5 + 1.036 \frac{2.7}{\sqrt{295} })[/tex]
( 26.5 - 0.1628 , 26.5+0.1628)

Answer:
∠U = 31°
Step-by-step explanation:
∠W has an exterior angle next to it, making them supplementary angles. This means they equal 180° together. First, we solve for ∠W:
∠W + 84 = 180
∠W = 96
We know that ∠W is 96°.
We know that the sum of the angles of a triangle is 180°. Knowing that we can solve for ∠U:
96 + 53 + ∠U = 180
149 + ∠U = 180
∠U = 31
Therefore, ∠U = 31°

1) Ms. Kitts works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this week. Ms. Kitts sold a total of 108 CDs over the 2 weeks. Which system of equations can be used to find L, the number of CDs she sold last week, and t, the number of CDs she sold this week?
Answer:
L = 3t + 6
108 = L + t
Step-by-step explanation:
first, define the variables:
L = # of CDs sold last week
t = # of CDs sold this week
then, let's write what the words of problem tells us in numbers:
"Last week (L), she sold 6 more (+ 6) than 3 times the number of CDs she sold this week (3t)
L = 3t + 6
"She sold a total of 108 CDs over 2 weeks (L + t)
108 = L + t

2х - 5 y = - 6
Чx - 3 = - 12.
Answer:
Step-by-step explanation:
2x -5y = -6 === (1)
4x-3 =-12 ====(2)
From (2), 4x= -12 +3
4x= -9
x= -2[tex]\frac{1}{4}[/tex]
Subst x= -2[tex]\frac{1}{4}[/tex] in (1), 2(-2[tex]\frac{1}{4}[/tex]) - 5y = -6
-4[tex]\frac{1}{2}[/tex] -5y = -6
-5y = -6 +4[tex]\frac{1}{2}[/tex]
-5y = -1[tex]\frac{1}{2}[/tex]
y = 0.3
Abby is trying to pay off her debt. She owes $422 to her bank. In may she paid $76, but had to borrow an additional $135. In June she paid $45 and borrowed $110. The bank also charged her $58 in interest. How much did she owe at the end of June.
Extra points
Answer: 624
Step by Step Explanation: Subtract 422 with 76, add 135, subtract 45, add 110, and lastly add 58.
Subtract 422 with 76, 422-76=366.
Add 366 with 135, answer will be 501.
Subtract 501 with 45 since she paid $45. 501-45=456.
Add 456 with 110 and that would be 566.
For the last step add 58 to find the answer and you would get 624.
Final Result: 624.
