A university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors. The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is a history major and the second student is a nursing major?
Answers
Answer:
6.9%.
Step-by-step explanation:
Given that a university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors, and the professor is planning to select two of the students for a demonstration, where the first student will be selected at random, and then the second student will be selected at random from the remaining students, to determine what is the probability that the first student selected is a history major and the second student is a nursing major the following calculations must be performed:
26 = 100
9 = X
9 x 100/26 = X
900/26 = X
34.61 = X
25 = 100
5 = X
500/25 = X
20 = X
0.2 x 0.3461 = X
0.069 = X
Thus, the probability that the first student selected is a history major and the second student is a nursing major is 6.9%.

This table models function m.
Answers
Answer:
A: The y-intercept of function m is less than that of function n.
Step-by-step explanation:
From the table, we see that when x = 0, m(x) = -6.
This means that the y-intercept of function m is -6.
For the function "n", we are told it passes through (-1, 0) and (0, 2)
We see that at the second coordinate, at x = 0, y = 2.
This means that the y-intercept of the n function is at 2.
Therefore,we conclude that the y-intercept of function m is less than that of function n.
MADD (Mother's Against Drunk Drivers) wishes to estimate the proportion of adult drivers that have run at least one red light in the last month. A poll is conducted on a simple random sample of adult drivers and it is found that out of 1251 adult drivers, 641 of them have run at least one red light in the last month. You will be finding a 90% confidence interval for the fraction of adult drivers that run at least one red light in the last month.
Required:
Check that the normality assumptions are met?
Answers
Answer:
Normality assumptions are met.
The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
A poll is conducted on a simple random sample of adult drivers and it is found that out of 1251 adult drivers, 641 of them have run at least one red light in the last month.
This means that [tex]n = 1251, \pi = \frac{641}{1251} = 0.5124[/tex]
Normality assumptions:
We need that: [tex]n\pi \geq 10, n(1-\pi)\geq 10[/tex]
We have that:
[tex]n\pi = 1251*0.5124 = 641[/tex]
[tex]n(1-\pi) = 1261*0.4876 = 610[/tex]
So normality assumptions are met.
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 - 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.4892[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 + 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.5356[/tex]
The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356).

In one house, a realtor decorates 4 twin beds and 1 queen bed with a total of 18 pillows.
In another house, she decorates 4 twin beds and 4 queen beds with a total of 36 pillows.
She puts the same number of pillows on each twin bed, and the same number of pillows on each queen bed.
How many pillows does she put on each twin bed?
How many pillows does she put on each queen bed?
Answers
Answer:
The answer would be 3 pillows on each twin bed and 6 pillows on each queen bed.
Step-by-step explanation:
first house:
3 pillows x 4 twin beds = 12 pillows
18 total pillows - 12 twin bed pillows = 6 queen bed pillows
Second house
6 queen bed pillows x 4 queen beds = 24 queen bed pillow
3 twin bed pillows x 4 twin beds = 12 twin bed pillows
24 queen bed pillow + 12 twin bed pillows = 36 total pillows
Answer:
3 pillows on each twin bed and 6 pillows on each queen bed.

Answer:
Step-by-step explanation:
5 feet ÷ 8 = 5/8 of a foot for each rod.
(In inches that would be 5/8 × 12 inches = (5 × 12)/8 inches = 60/8 inches = 15/2 inches = 7 1/2 inches.)
13 rods would be 13 × 5/8 feet = (13 × 5)/8 feet = 65/8 feet = 8 1/8 feet
JK, KL and LJ are all tangent to O (not drawn to scale). JA = 13, AL = 9, and
CK = 11. Find the perimeter of JKL.
a.)66
b.)44
c.)33
d.)48
Answers
Answer:
a.) 66
Step-by-step explanation:
Perimeter of JKL = JA + AL + CK + CL + KB + JB
JA = 13,
AL = 9,
CK = 11
CL = AL = 9 (tangents drawn from an external point are congruent)
KB = CK = 11 (tangents drawn from an external point are congruent)
JB = JA = 13 (tangents drawn from an external point are congruent)
Plug in the values
Perimeter of JKL = 13 + 9 + 11 + 9 + 11 + 13
= 66

What are the two whole numbers whose product is 294 and whose quotient is 6?
Answers
Answer: 7 and 42.
Step-by-step explanation:
Let the two whole numbers be x and y.
From the question given, we can form an equation as:
x × y = 294 ........ i
x/y = 6 .......... ii
From equation ii
x/y = 6
x = 6y
Put the value of x back into equation i
x × y = 294
6y × y = 294
6y² = 294
y² = 294/6
y² = 49
y = ✓49
y = 7
Since x × y = 294 and y = 7,
x = 294/7
x = 42
The numbers are 7 and 42.
