A poll is given, showing 30% are in favor of a new building project.
If 5 people are chosen at random, what is the probability that exactly 4 of them favor the new building project?
Answer:
0.02835
Step-by-step explanation:
Let p be the probability who are in favor of the project and q be the probability who are not in favor of the project.
p = 30% = 0.30
q = 1 - p = 1 - 0.30 = 0.70
n = 5, x = 4
Now, by binomial distribution formula:
[tex]P(X=x)=^nC_x \:p^x \:q^{n-x}[/tex]
[tex]\implies P(X=4)=^5C_4\: (0.30)^4\: (0.70)^{5-4}[/tex]
[tex]\implies P(X=4)=5 (0.30)^4 \:(0.70)^{1}[/tex]
[tex]\implies P(X=4)=5 (0.0081) \:(0.70)[/tex]
[tex]\implies P(X=4)=0.02835[/tex]
The probability that exactly 4 of them favor the new building project is 0.02835.

Step-by-step explanation:
A plant is already 43 centimeters tall, and it will grow one centimeter every month.
Let H be the plant's height (in centimeters) after M months.
Write an equation relating H to M. Then use this equation to find the plant's height after 21 months.
Answer:
h=m+43, 66cm
Step-by-step explanation:
For each month, it grows by one centimeter, which is represented by 1m or just m. You also have to add the height it already has, which makes h=m+43. For 21 months, substitute 21 for m to get h=21+43 which simplifies into h=66 cm

write equivalent fractions for 2/3 and 1/4using 12 as the common denominator
Answer:
2/3 = 8/12
1/4 = 3/12
Step-by-step explanation:
2/3
12/3 = 4, so for the fraction 2/3, we multiply the numerator and denominator by 4.
2/3 = 8/12
1/4
12/4 = 3, so for the fraction 1/4, we multiply the numerator and denominator by 3.
1/4 = 3/12
Answer:
[tex]\frac{8}{12}[/tex] and [tex]\frac{3}{12}[/tex]
Step-by-step explanation:
To do this, you must multiple the numerator and denominator of each fraction by whatever number gives you 12 on bottom.
for [tex]\frac{2}{3}[/tex] , you would multiply it by 4 since 4×3=12. You would also need to multiply the top by 4, making that fraction [tex]\frac{8}{12}[/tex]
For [tex]\frac{1}{4}[/tex] , multiply it by 3, which would equal [tex]\frac{3}{12}[/tex]

The potato is 325 feet in the air after
seconds on the way back down.
Submit Question
seconds on the way up and after
Answer:
1.68 seconds.
Step-by-step explanation:
The question, is, essentially asking for time, t, at position 325 feet.
So:
Set h(t) equal to 325.
325 = 16t^2 + 168t + 5
Subtract 325 over, to get the quadratic:
0 = 16t^2 + 168t - 320
Factor out an eight, simply to make the equation easier:
0 = 2t^2 + 21t - 41
Now, use the quadratic formula to find the "zeros", or solutions:
{-21 + (21^2 - [(4)(2)(-41)]^.5}/(2)(2); {-21 - (21^2 - [(4)(2)(-41)]^.5}/(2)(2)
Simplify:
(-21 + [441 + 328]^.5)/4; (-21 - [441 + 328]^.5)/4
(-21 + [769]^.5)/4; (-21 - [769]^.5)/4
(-21 + 27.73)/4; (-21 - 27.73)/4
(6.73)/4; (-48.73/4)
t = 1.68, -12.18
It makes no sense for t to be negative, since t represents time.
Therefore, the potato is 325 feet in the air after 1.68 seconds.
I hope this helped! :)
The potato is 325 feet in the air after 1.68 seconds on the way back down.
What is a quadratic function?The quadratic function is defined as a function containing the highest power of a variable is two.
The question is effectively inquiring about time, t, at 325 feet.
Set h(t) equal to 325.
325 = 16t² + 168t + 5
Subtract 325 over, to get the quadratic:
0 = 16t² + 168t - 320
Factor out an eight, simply to make the equation easier:
0 = 2t² + 21t - 41
2t² + 21t - 41 = 0
Compare the given function to the standard quadratic function f(x) = ax² + b x + c.
We get a = 2, b = 2 and c = -12
Now, use the quadratic formula to find the "zeros", or solutions:
[tex]\quad x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]t=\dfrac{-21\pm \sqrt{21^2-4\cdot \:2\left(-41\right)}}{2\cdot \:2}[/tex]
[tex]\sqrt{21^2-4\cdot \:2\left(-41\right)}[/tex]
[tex]=\sqrt{21^2+328}[/tex]
t = (-21 + 27.73)/4; (-21 - 27.73)/4
t = (6.73)/4; (-48.73/4)
t = 1.68, -12.18
Because t symbolizes time, it makes no sense for it to be negative.
As a result, after 1.68 seconds, the potato is 325 feet in the air.

C) 5x + 3.5 < 3x + 4
D) 5x + 3.5 > 3x + 4
Answer:
B
Step-by-step explanation:
the options A and B are the ones that make sense
to get rid of one of the options, you have to substitute.

The rectangle below has an area of x^2-7x+10x and a width of x-5x−5x meters.
What expression represents the length of the rectangle?
Answer:
The expression for length of the rectangle is x-2 meters.
Step-by-step explanation:
Given the area of the rectangle as : x²- 7x+10 square meters
The width of the rectangle is : x-5 meters
Area of a rectangle is given by the product of its length and width.
Dividing the expression for area with the expression for width will give the expression for length.
Here, perform the long division of the polynomial; where the numerator is x²- 7x+10 and the denominator is x-5
First divide x²- 7x+10 by x-5 to get x
Multiply x by x-5 to get x²-5x
Subtract x²-5x from x²-7x+10 to get -2x+10
Then divide -2x+10 by x-5 to get -2
Multiply x-5 by -2 to get -2x+10
Perform subtraction to remain with zero.
The expression for length will now be x-2 meters

Each month, Morse budgets $3,900 for fixed expenses, $676 for living expenses, and $561 for annual expenses. His annual net income is $67,796. Describe his monthly budget by using a positive number to show how much of a surplus there is, a negative number to show how of a deficient there is, or zero if it is a balance budget.
Show work clearly for 100 POINTS!!!
Answer:
$512.67 (surplus)
Step-by-step explanation:
Monthly fixed expenses = $3,900
Monthly living expenses = $676
Monthly annual expenses = $561
⇒ Total monthly expenses = 3900 + 676 + 561 = $5,137
Annual net income = $67,796
⇒ Monthly net income = $67,796 ÷ 12 = $5,649.67
Monthly budget = Monthly net income - Total monthly expenses
= $5,649.67 - $5,137
= $512.67 (surplus)
