Answer:
x = 16
Step-by-step explanation:
I could be wrong so sorry in advance lol but this is what I did:
I made the equation 3x + 3 = ((7x-10)/2)
I divided the 2nd equation by 2 so that it would be the same length as RZ.
after that, I got: 3x + 3 = 3.5x - 5
from there, i did basic algebra to get the answer 16
hope this helps!
The average monthly mortgage payment for all homeowners in a city is $2870. Suppose that the distribution of monthly mortgages paid by homeowners in this city follow an approximate normal distribution with a mean of $2870 and a standard deviation of $470. Find to 4 decimal places the probability that the monthly mortgage paid by a randomly selected homeowner from this city is
Answer:
The probability that the monthly mortgage is between 2300 and 3140 is: 0.23167
Step-by-step explanation:
Given
[tex]\mu = 2870[/tex] --- the average
[tex]\sigma = 470[/tex] --- the standard deviation
Required [Missing from the question]
Monthly mortgage is between 2300 and 3140
This is represented as:
[tex]P(2300 < x < 3140)[/tex]
This is calculated as:
[tex]P(a< x < b) = P(z_a < Z < z_b)[/tex]
[tex]P(2300< x < 3140) = P(z_b < Z < z_a)[/tex]
Calculate the z scores
[tex]x = 3140[/tex]
[tex]z = \frac{3140 - 2850}{470}[/tex]
[tex]z = \frac{290}{470}[/tex]
[tex]z = 0.6170[/tex]
[tex]x = 2300[/tex]
[tex]z = \frac{3140 - 2300}{470}[/tex]
[tex]z = \frac{840}{470}[/tex]
[tex]z = 1.7872[/tex]
So, we have;
[tex]P(2300< x < 3140) = P(1.1787 < Z < 0.6170)[/tex]
This is then calculated as:
[tex]P(a < Z < b) = P(Z < a) - P(Z <b)[/tex]
[tex]P(a < Z < b) = P(Z < 1.1782) - P(Z <0.6170)[/tex]
[tex]P(2300< x < 3140) = P(Z < 1.1782) - P(Z <0.6170)[/tex]
Using the z table:
[tex]P(Z<0.6170) =0.73138[/tex]
[tex]P(Z<1.7872) =0.96305[/tex]
[tex]P(2300< x < 3140) = 0.96305 - 0.73138[/tex]
[tex]P(2300< x < 3140) = 0.23167[/tex]

For the area of the rectangle is 10 square inches. Determine both dimensions of the length is 8 inches les than than twice the width. A. Write an equation (in "x") to solve the problem. B. Find the solution(s).
Answer:
x² - 4x - 5 = 0
Width of rectangle = 5 inch
Length of rectangle = 2 inch
Step-by-step explanation:
Given:
Area of rectangle = 10 inch²
Length of rectangle = 2[Width of rectangle] - 8
Find:
Equation
Value of length and width
Computation;
Assume;
Width of rectangle = x
So,
Length of rectangle = 2[Width of rectangle] - 8
Length of rectangle = 2x - 8
Area of rectangle = Length × Width
10 = x(2x - 8)
2x² - 8x - 10 = 0
Divide by 2 from both side
x² - 4x - 5 = 0
x² - (5-1)x - 5 = 0
x² - 5x + x- 5 = 0
x(x - 5) + 1(x - 5)
x = 5 and x = -1
So,
Width of rectangle = 5 inch
Length of rectangle = 2x - 8
Length of rectangle = 2(5) - 8
Length of rectangle = 2 inch

Need help pls ASAP no jokes need this badly
Answer:
x=64°
................
=============================================================
Explanation:
Combining all of the angles shown in the diagram leads to 360 degrees. This is because there are 360 degrees in a full rotation.
Let's add up the angles shown and set the sum equal to 360. Keep in mind that the square angle marker represents 90 degrees (aka a right angle).
180+26+x+90 = 180
x+296 = 360
x = 360-296
x = 64

Explain how 17.526 could be rounded to both 18 and 17.5.
Answer:
Step-by-step explanation:
If you round it to the nearest whole number, then 17.526 becomes 18 because if the first digit after the decimal(in this case,5) is 5 or greater you round to the next whole number.
If you round it to the nearest tenth, it would result in 17.5, because if the second digit after the decimal (in this case, 2) is 5 or greater you round to the next tenth of decimal.
Hope this helps!
Answer:
Step-by-step explanation:
It can be rounded down to 17.5 if rounding to 1 decimal place. If you are rounding to the nearest whole number, you would round to 18.
Hope this helps :)

Find the probability of exactly two
successes in five trials of a binomial
experiment in which the probability of
success is 50%.
Round to the nearest tenth of a
percent.
[? ]%
Answer:
31.3%
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Five trials, probability of a success is 50%.
This means that [tex]n = 5, p = 0.5[/tex]
Probability of exactly two successes
This is P(X = 2). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.313[/tex]
0.313*100% = 31.3%
