Answer:
12.327X + 452.084
45206.327
Step-by-step explanation:
The linear regression model obtained by fitting the data using technology is :
ŷ = 12.327X + 452.084
Where, 12.327 = slope ; 452.084 = Intercept ; X = appraised value ; y = Area
The estimated error variance which is the degree of variation between the actual and predicted value.
Error variance = ΣSSE /n-2
n = sample size = 15
ΣSSE = 587682.2638
Error variance = 587682.2638/13
Error variance = 45206.327

Answer:
<1= 62
•it is 62 because it is an alternate interior angle which is congruent
<2= 83
• when you add the given angles 62 and 35 you get 97 and a triangle is 180 so you subtract 97 from 180
<3=35
• it is 35 because it is an alternate interior angle which is congruent
Step-by-step explanation:
62+35= 97
180-97= 83

A jockey will ride horses in 10 different races at a race track today. The number of races that the jockey will win is what type of random variable
Answer:
X is a discrete Random variable where X is the number of races Jockey can win.
Step-by-step explanation:
To find - A jockey will ride horses in 10 different races at a race track today.
The number of races that the jockey will win is what type of random variable ?
Proof -
Given that,
A jockey will ride horses in 10 different races at a race track today.
Let us assume that,
X is the number of races Jockey can win
So,
X can take value 0, 1, 2, 3, ......10
As,
It can take countable finite values
So,
X is a discrete Random variable
∴ we get
X is a discrete Random variable where X is the number of races Jockey can win.
If the amount of time to prepare and deliver a pizza from MOD PIZZA is normally distributed with a mean of 20 minutes and standard deviation of 5 minutes.
Determine the percent of pizzas that were prepared and delivered:
(a) Between 20 and 25 minutes (b) In less than 18 minutes
( c ) If MOD PIZZA advertises that the Pizza is free if it takes more than 30 minutes to deliver, what percent of the pizza will be free?
I need to answer a,b and c - it is not mutiple choice. I also need to show all relevant steps and plus I really want to understand how to do this! I am completely stuck on this one and its due tonight. Please help!! :) Ill give badges, brainliest, thanks, all of that for whoever can help me!
Using the normal distribution, we have that:
a) 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.
b) 34.46% of pizzas were prepared and delivered in less than 18 minutes.
c) 2.28% of the pizza will be free.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 20, \sigma = 5[/tex]
For item a, the probability is the p-value of Z when X = 25 subtracted by the p-value of Z when X = 20, hence:
X = 25:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{25 - 20}{5}[/tex]
Z = 1
Z = 1 has a p-value of 0.8413.
X = 20:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{20 - 20}{5}[/tex]
Z = 0
Z = 0 has a p-value of 0.5.
0.8413 - 0.5 = 0.3413.
Hence 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.
For item b, the probability is the p-value of Z when X = 18, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{18 - 20}{5}[/tex]
Z = -0.4
Z = -0.4 has a p-value of 0.3446.
34.46% of pizzas were prepared and delivered in less than 18 minutes.
For item c, the proportion is one subtracted by the p-value of Z when X = 30, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30 - 20}{5}[/tex]
Z = 2
Z = 2 has a p-value of 0.9772.
1 - 0.9772 = 0.0228, hence 2.28% of the pizza will be free.

A sprinter ran the 400 meter dash in 44.62 seconds. Convert her speed into miles per hour
Answer:
v = 20.7 mph
Step-by-step explanation:
Given that,
Distance, d = 400 m
Time, t = 44.62 s =
We need to find the speed of the sprinter. The speed of an object is defined as total distance covered divided by time taken. It can be given by :
[tex]v=\dfrac{d}{t}\\\\=\dfrac{0.248\ mile}{0.012\ s}\ (As\ 1\ m=0.000621371\ mile)\\\\=20.7\ mph[/tex]
Hence, the speed of the sprinter is equal to 20.7 mph.
A local department store sells carpet in 4 sizes. Each carpet comes in 3 different qualities. One of the sizes comes in 5 colors. The other sizes come in 2 colors. How many choices of carpet are there
Answer:
23.
Step-by-step explanation:
You would multiply the 4 sizes of carpet by the 3 qualities, which equals 12. Then, you add 5+2+2+2. So it would end up being 12+11.

[tex]x {}^{2} \div a + y {}^{2} \div b = 1[/tex]
find x
Answer:
[tex]x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]
Step-by-step explanation:
The given equation is :
[tex]x^2\div a+y^2\div b=1[/tex]
We need to find the value of x.
It can also written as :
[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}=1[/tex]
Subtract [tex]\dfrac{y^2}{b}[/tex] from both sides,
[tex]\dfrac{x^2}{a}+\dfrac{y^2}{b}-\dfrac{y^2}{b}=1-\dfrac{y^2}{b}\\\\\dfrac{x^2}{a}=\dfrac{b-y^2}{b}\\\\\text{Cross multiplying both sides}\\\\x^2=\dfrac{a(b-y^2)}{b}\\\\x=\sqrt{\dfrac{a(b-y^2)}{b}}[/tex]
Hence, the value of x is equal to [tex]\sqrt{\dfrac{a(b-y^2)}{b}}[/tex].

it takes electricians 36 days to wire a new housing subdivision. how many days would 32 electricians take to do the same job?
Answer:
The 32 electricians will take 1 day and 3 hours to complete the wiring.
Step-by-step explanation:
Since it takes electricians 36 days to wire a new housing subdivision, to determine how many days would 32 electricians take to do the same job the following calculation must be performed:
36/32 = X
1.125 = X
1 = 24
0.125 = X
0.125 x 24 = X
3 = X
Therefore, the 32 electricians will take 1 day and 3 hours to complete the wiring.
