Solve for x in terms of h.
10x + 20h = -4(-3x - 8h)
Answer:
x= -6h
Step-by-step explanation:
opening up the bracket
10x+20h=12x+32h
10x-12x=32h-20h
-2x=12h
x=-6h
Answer:
x=-6h

Find the value of xx in the equation below
X - 15.4 = 19.1
Answer:
x = 34.5
Step-by-step explanation:
x - 15.4 = 19.1
Add 15.4 to both sides.
x - 15.4 + 15.4 = 19.1 + 15.4
x = 34.5
Answer:
x equals -3

A circle has a radius of 5 centimeters. What is the area?
Answer:
[tex]25\pi[/tex]
Step-by-step explanation:
The formula for the area of a circle is [tex]A=\pi r^{2}[/tex], r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however [tex]25\pi[/tex] is the exact answer.
The number of nails in a 5 lb box is normally distributed with a mean of 325 nails and a standard deviation of 15 nails
Suppose that 1200 different 5 lb boxes are in a warehouse.
About how many boxes contain more than 340 nails?
O 170
O 192
O 340
O 384
Answer: 192.. just took the test :)
Step-by-step explanation:
The number of boxes contains more than 340 nails will be 190. Option B is correct.
What is Z score?The number of standard deviations by which the value of a raw score is above or below the mean value of what is being observed or measured is known as the Z score.
Z score for the 340 nails is found as;
[tex]\rm Z-score= \frac{340-325}{15} \\\\ Z-score=1[/tex]
If the probability of the z score is grater than 1 is;
P(Z≥1)=1-P(Z≤1)
P(Z≥1)=1-0.8413
P(Z≥1)=0.1587
For the 1200 boxes with more than the 340 nails is 192.
Hence,option B is correct.

Step-by-step explanation:
Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, of all homeowners are insured against earthquake damage. Four homeowners are to be selected at random; let denote the number among the four who have earthquake insurance.
1. Find the probability distribution of X. [Hint: Let S denote a homeowner who has insurance and one who does not. Then one possible outcome is SFSS, with probability (.25)(.75)(.25)(.25) and associated X value 3. There are 15 other outcomes].
2. What is the most likely value for X?
3. What is the probability that at least two of the four selected have earthquake insurance?
Missing part of the question
Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, 25% of all homeowners.....................
Answer:
[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]
[tex]Mean = 1[/tex]
[tex]Pr = 0.2617[/tex]
Step-by-step explanation:
Given
[tex]n = 4[/tex]
[tex]p = 25\%[/tex]
Solving (a): The probability distribution of x
We have:
[tex]n = 4[/tex]
[tex]p = 25\%[/tex] [tex]= 0.25[/tex]
The probability of not having earthquake insurance (q) is:
[tex]q = 1 - p[/tex]
[tex]q = 1 - 0.25[/tex] [tex]= 0.75[/tex]
If x has insurance, then n - x do not.
The distribution follows a binomial pattern. So, the probability distribution is:
[tex]P(X = x) = ^nC_x * 0.25^x * 0.75^{n-x}[/tex]
Substitute 4 for n
[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]
Solving (b): The most likely value of x i.e. The mean
We have:
[tex]n = 4[/tex] and
[tex]p = 25\%[/tex] [tex]= 0.25[/tex]
[tex]Mean = np[/tex]
[tex]Mean = 4 * 0.25[/tex]
[tex]Mean = 1[/tex]
Solving (c): At least 2 of 4 selected have earthquake insurance.
This is calculated as
[tex]Pr = P(x = 2) + P(x = 3) + P(x = 4)[/tex]
[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]
[tex]P(X=2) = ^4C_2 * 0.25^2 * 0.75^{4-2}[/tex]
[tex]P(X=2) = 6 * 0.25^2 * 0.75^2 = 0.2109375[/tex]
[tex]P(X=3) = ^4C_3 * 0.25^3 * 0.75^{4-3}[/tex]
[tex]P(X=3) = 4 * 0.25^3 * 0.75 = 0.046875[/tex]
[tex]P(X=4) = ^4C_4 * 0.25^4 * 0.75^{4-4}[/tex]
[tex]P(X=4) = 1 * 0.25^4 * 1= 0.00390625[/tex]
So:
[tex]Pr = P(x = 2) + P(x = 3) + P(x = 4)[/tex]
[tex]Pr = 0.2109375 + 0.046875 + 0.00390625[/tex]
[tex]Pr = 0.26171875[/tex]
[tex]Pr = 0.2617[/tex] --- approximated

k= y/x (3x-1)-2.75(x+2)
Answer:
k=
−2.75x2+3xy−5.5x−y/x
Step-by-step explanation:
Hi! so i see you need help with this problem let me help you and guide you through the steps :]
Let's solve for k.
k= y/x
(3x−1)−2.75(x+2)
Step 1: Multiply both sides by x.
kx=−2.75x2+3xy−5.5x−y
Step 2: Divide both sides by x.
kx/x
=
−2.75x2+3xy−5.5x−y/x
k=
−2.75x2+3xy−5.5x−y/x
Answer:
k=
−2.75x2+3xy−5.5x−y/x

During the fall you charge $10 to go to a house and rake the leaves and an additional eight dollars for every hour that you rake the yard if you earned $42 how many hours did you spend raking the leaves
Answer:
4
Step-by-step explanation:
set up an equation:
let h be the number of hours you spent raking.
then, the cost would be 10 + 8 times the number of hours.
In equation form:
[tex]10 + 8h = 42[/tex]
solve:
[tex]10 + 8h = 42\\8h = 32\\h = 4[/tex]
So you worked for 4 hours

A perfect square is the product of any positive whole number used as a factor exactly two times. [Example: 49 is a perfect square because 7 × 7 = 49] … The positive whole number N, when multiplied by 150, is a perfect square.
Answer:
6
Step-by-step explanation:
The computation of the least possible whole number is shown below:
Here we need the factors of 150 i.e.
= 3 × 5 × 2 × 5
Here we can add to one box and the 5 to the other box
And, now if we can add 3 to one box and in the other we can add 2 so they cant be equal to each other
Now lets try 5 × 6 and 5
So, here The perfect square is 900
= 30 × 30
= 900
Hence, the number would be 6
