johns rent is $1,355. what is his standardized z-score
Answer:
His standardized z-score is [tex]Z = \frac{1355 - \mu}{\sigma}[/tex], in which [tex]\mu[/tex] is the mean price of rents and [tex]\sigma[/tex] is the standard deviation for price of rents.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Johns rent is $1,355.
This means that [tex]X = 1355[/tex]
What is his standardized z-score
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1355 - \mu}{\sigma}[/tex]
His standardized z-score is [tex]Z = \frac{1355 - \mu}{\sigma}[/tex], in which [tex]\mu[/tex] is the mean price of rents and [tex]\sigma[/tex] is the standard deviation for price of rents.

Answer:
Let us first jot down all the data given in the question;
Number of low quality computers (LQ) = 72
Number of medium quality computers (MQ) = 112
Number of high quality computers (HQ) = 711
∴ Total number of computers found in a random sample = 72 + 112 + 711 = 895.
∴ To find the probability of purchase for each category of computers, we use the following formula;
So,
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Ans) Probability of purchase of a low quality computer, a medium quality computer, and a high quality computer are 0.08, 0.125, and 0.794 respectively

down payment?
$325000
$375000
$75000
$300,000
Answer:
$300000
Step-by-step explanation:
down-payment would $75000 so minus it from $375000 to get the mortgage
Answer:300000
Step-by-step explanation:
375000/100 =3750
1 percent = 3750
20 percent = 3750*20=75000
375000-75000= 300000

The 20-oz iced tea has
calories
Answer:
[tex]180\:\text{calories}[/tex]
Step-by-step explanation:
The question implies a constant rate or distribution of calories. Therefore, we can set up the following proportion:
[tex]\frac{14}{126}=\frac{20}{x},\\14x=20\cdot 126,\\14x=2520,\\x=\boxed{180\:\text{calories}}[/tex]

Whats the Diameter? I really need help understanding this
Answer:
1.8 in.
Step-by-step explanation:
Hi there!
1) Determine the radius of the base
[tex]V=\frac{1}{3} \pi r^2h[/tex] where r is the radius of the base and h is the height of the cone
Plug in the known values (h=4.2, V=3.6)
[tex]3.6=\frac{1}{3} \pi r^2(4.2)[/tex]
Isolate r; divide both sides by 4.2
[tex]\frac{3.6}{4.2} =\frac{1}{3} \pi r^2\\\frac{6}{7} =\frac{1}{3} \pi r^2[/tex]
Multiply both sides by 3
[tex]\frac{6}{7}*3 =\pi r^2\\\frac{18}{7}=\pi r^2[/tex]
Divide both sides by π
[tex]\frac{18}{7\pi }=r^2[/tex]
Take the square root of both sides
[tex]\sqrt{\frac{18}{7\pi }} =r[/tex]
2) Determine the diameter
Now that we have the radius, to find the diameter, multiply r by 2:
[tex]d=\sqrt{\frac{18}{7\pi }}*2\\d=1.8[/tex]
Therefore, the diameter is 1.8 in. when rounded to the nearest tenth.
I hope this helps!
Answer:
1.8 in
Step-by-step explanation:
we know the equation for the volume of a cone is pi*r^2 h/3=3.6
pi r^2 *4.2=10.8
solve for r
r is about 0.9 so diameter is 1.8 in
Quadratic below
2^2−7−4
Vertex -
Y-Intercept -
X-Intercept -
Answer:
The y-intercept is y = -4.
The x-intercepts are [tex]x = 4[/tex] and [tex]x = -\frac{1}{2}[/tex]
The vertex is [tex](\frac{7}{4},-\frac{81}{8})[/tex]
Step-by-step explanation:
Quadratic equation:
Has the following format:
[tex]y = ax^2 + bx + c[/tex]
The y-intercept is c.
Finding the x-intercepts:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
Vertex:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
In this question:
The quadratic equation is [tex]2x^2 - 7x - 4[/tex], which has [tex]a = 2, b = -7, c = -4[/tex]. This means that the y-intercept is y = -4.
x-intercepts:
[tex]\Delta = (-7)^2-4(2)(-4) = 81[/tex]
[tex]x_{1} = \frac{-(-7) + \sqrt{81}}{2*2} = 4[/tex]
[tex]x_{2} = \frac{-(-7) - \sqrt{81}}{2*2} = -\frac{1}{2}[/tex]
The x-intercepts are [tex]x = 4[/tex] and [tex]x = -\frac{1}{2}[/tex]
Vertex:
[tex]x_{v} = -\frac{(-7)}{2*2} = \frac{7}{4}[/tex]
[tex]y_{v} = -\frac{81}{4(2)} = -\frac{81}{8}[/tex]
The vertex is [tex](\frac{7}{4},-\frac{81}{8})[/tex]
The population of leave town is 1-23,560 and is decreasing at a rate of 1.5%
each
year.
a) when will the population of Leavetown drop below 47,000 Cto the nearest
year)?
b) what will the population of leavetown be years from now?
Answer: a is correct
Step-by-step explanation:
At 25 years
Step-by-step explanation:
123,000 x 2.375% = 2,921.25. This gives you the rate that the population is decreasing. How long will it take to get to 50,000. Do reverse operations to find this answer: 123,000 - 50,000 = 73,000, the population need to decrease by 73,000 to get to 50,000. So let's multiply our rate of 2,921.25 x 25 = 73,031 and our final step.. 123,000 - 73,031 = 49,969 below 50,000

If two angles are complementary and one angle is 50º what is the measure of the other angle?
Answer: 40 degrees

The perimeter of a triangle is 64 in. The longest side is 14 in. Longer than the medium side, and the medium side is 7 in. more than the shortest side. Find the length of each side of the triangle
Answer:
longest side =33
medium side =19
shortest side = 12
Step-by-step explanation:
Let medium side be x
then longest side =14 +x
shortest side = x-7
we know that ,
perimeter =sum of all side
or, 64 = 14+ x + x + x -7
or, 64 - 7 = 3x
or, 57 = 3x
or, 57÷3 = x
or, x = 19
then
medium side =x = 19
longest side =x+14 =33
shortest side = x- 7 = 12 #
