About 35% of all U.S. households have a cellular phone. If you called 7 households what's the probability that, a. All 7 households have a cellular phone? a= b. Exactly 4 households have a cellular phone? b = c. Fewer than 2 households have a cell phone? c = d. At least 6 households have a cellular phone? d = e. At least 1 household has a cellular phone? e =
Answer:
p = 0.35
q = 0.65
n = 7
Step-by-step explanation:
To calculate the distribution, we have the following values;
p = 35% = 35/100 = 0.35
q = 1-p = 1-0.35 = 0.65
n = 7

the data shows the length and weight of a species of fish based on the data
which is closest to the length of a fish that weighs 4.2 pounds
Answer:
36.5 inches
Step-by-step explanation:
Given
See attachment for the given data
Required
Which length is closest to 4.2lb
The given data is a linear dataset.
So, we start by calculating the slope (m)
[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Pick any two corresponding points from the table
So, we have:
[tex](x_1,y_1) = (8,1.21)[/tex]
[tex](x_2,y_2) = (12,1.63)[/tex]
So:
[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m =\frac{1.63 - 1.21}{12 - 8}[/tex]
[tex]m =\frac{0.42}{4}[/tex]
[tex]m =0.105[/tex]
The linear equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = 0.105 * (x - 8) + 1.21[/tex]
Open bracket
[tex]y = 0.105x - 0.84 + 1.21[/tex]
[tex]y = 0.105x + 0.37[/tex]
To get the length closest to 4.2lb,
we set [tex]y = 4.2[/tex]
Then solve for x
So, we have:
[tex]y = 0.105x + 0.37[/tex]
[tex]4.2 = 0.105x + 0.37[/tex]
Collect like terms
[tex]0.105x= 4.2 - 0.37[/tex]
[tex]0.105x= 3.83[/tex]
Solve for x
[tex]x= 3.83/0.105[/tex]
[tex]x\approx 36.5[/tex]

In the above figure, m∠A = 22° and m∠B = (2x + 16)°. If angles A and B are complementary angles, what are the value of x and the measure of angle B?
A.
x = 26, m∠B = 68°
B.
x = 71, m∠B = 158°
C.
x = 48, m∠B = 68°
D.
x = 26, m∠B = 52°
Answer:
A.
Step-by-step explanation:
22+(2x + 16)+90=180
combine like terms: 90+22+16=128
180-128=52
52=2x
52/2 = 2x/2
26 = x

Q3. If a=b c, b= c a and c = a b then prove that abc=1.
Q4. If a= 5x, b= 5y and ay bx = 25, then prove that xy = 1
Step-by-step explanation:
Question 3 :
We have ,
a = bc . . . . . (i) b = ac . . . . . (ii)c = ab . . . . . (iii)Multiplying all three equations ,
=> a × b × c = bc * ac * ab
=> abc = a²b²c²
=> abc/a²b²c² = 1
=> 1/abc = 1
=> abc = 1

Jacob and his dad end up hiking up to the top. If the base of the mountain is 2,600 feet wide and the mountain is pretty much isosceles, what is the total distance that Jacob and his dad hiked from their campsite to the top of the mountain?
The total distance that Jacob and his dad hiked from their campsite to the top of the mountain is approximately 7,105.92 feet.
To calculate the total distance Jacob and his dad hiked from their campsite to the top of the mountain, we need to consider the width of the base of the mountain and the height of the mountain.
Given:
Base width of the mountain: 2,600 feet
Since the mountain is pretty much isosceles, we can assume that the height of the mountain is equal to the length of the two equal sides of the triangle formed.
To find the height of the mountain, we can use the Pythagorean theorem.
Let's assume the height of the mountain is 'h' feet.
Using the Pythagorean theorem, we have:
[tex](2,600/2)^2 + h^2 = 2,600^2[/tex]
Simplifying the equation:
[tex]1,300^2 + h^2 = 2,600^2\\1,690,000 + h^2 = 6,760,000[/tex]
[tex]h^2 = 6,760,000 - 1,690,000\\h^2 = 5,070,000[/tex]
Taking the square root of both sides:
h = sqrt(5,070,000)
h ≈ 2,252.96 feet
Now we can calculate the total distance they hiked from their campsite to the top of the mountain by considering the base width and the height of the mountain.
Total distance = Base width + 2 × Height
Total distance = 2,600 + 2 × 2,252.96
Total distance ≈ 2,600 + 4,505.92
Total distance ≈ 7,105.92 feet
Therefore, the total distance that Jacob and his dad hiked from their campsite to the top of the mountain is approximately 7,105.92 feet.

A study by the department of education of a certain state was trying to determine the
mean SAT scores of the graduating high school seniors. The study found that the
mean SAT score was 447 with a margin of error of 21. Write a confidence interval for
the true mean SAT score of the graduating high school seniors.
Answer:
(426 ; 468)
Step-by-step explanation:
Confidence interval :
Mean score ± margin of error
Margin of Error = 21
Mean SAT score = 447
Hence,
447 ± 21
Lower boundary = 447 - 21 = 426
Upper boundary = 447 + 21 = 468
(426 ; 468)
In what ratio must 40m3 be decreased to become 24m3?
Answer:
40m3 must be decreased by 40% to become 24m3.
Step-by-step explanation:
To determine in what ratio must 40m3 be decreased to become 24m3, the following calculation must be performed:
40 = 100
24 = X
24 x 100/40 = X
2400/40 = X
60 = X
100 - 60 = 40
Therefore, 40m3 must be decreased by 40% to become 24m3.
