Answer:
The Probability that someone lives in their home for 40 years or more
[tex]P(X\geq 40 ) = P( Z\geq3.50 )[/tex] = 0.0002
Step-by-step explanation:
Explanation:-
Given mean of the Population = 20 years
The standard deviation of the Population = 5.7 years
Let 'X' be the random variable in normal distribution
[tex]Z = \frac{x-mean }{S.D} = \frac{40-20}{5.7} = 3.508[/tex]
The Probability that someone lives in their home for 40 years or more
[tex]P(X\geq 40 ) = P( Z\geq3.50 )[/tex]
= 1 - P( Z< 3.50)
= 1 - ( 0.5 + A(3.50)
= 0.5 - 0.4998 ( from normal table )
= 0.0002

m over 8 minus 5 equal 12
Answer:
m = 136
Step-by-step explanation:
m/8 - 5 = 12
1. Add 5 on both sides
m/8 - 5 + 5 = 12 + 5
m/8 = 17
Multiply 8 on both sides since u are trying to isolate the variable
m/8 * 8 = 17*8
m = 136
Check
136/8 - 5 = 12
17 - 5 = 12
12 = 12
Hope it helped!
Step-by-step explanation:
[tex]\frac{m}{8}[/tex] - 5 = 12 : Original Problem
[tex]\frac{m}{8}[/tex] -5 +5 = 12 + 5 : Bringing the constants to one side
[tex]\frac{m}{8}[/tex] = 17 : Simplification
[tex]\frac{m}{8}[/tex]×8 = 17×8: Isolating the variable
m = 136 : The answer!!!
Checking the answer
[tex]\frac{136}{8}[/tex] -5 = 12 : Substitution
[tex]\frac{136}{8}[/tex] = 17 : Bringing constants to one side and simplification
136 = 17 × 8 : Isolating the answer
136 = 136 : Success!!!
I hope this is what you wanted and I hope this helps!!!

Solve the following equation for x.
5x + 15 = - 45
Answer:
-12
Step-by-step explanation:
5(-10)=-60
-60+15=
-45
Answer:
-12
Step-by-step explanation:
Reorder the terms:
15 + 5x = -45
Solving
15 + 5x = -45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = -45 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = -45 + -15
5x = -45 + -15
Combine like terms: -45 + -15 = -60
5x = -60
Divide each side by '5'.
x = -12 :)

HELP PLSSS Function g is a transformation x of f(x) = 2 ^ x Select all the true statements about the functions. (F-|F.2.4)
Answer:
its the second, not sure about 3
Step-by-step explanation:
2^x can never be negative
g is 2^x+4, which also can never be negative
neither have a y-intercept, so im not sure about three
but they have the same domain (-inf, inf), but not the same range, as g is always greater than 4, while f can be less than 4
and thus they don't have the same asymptote
both functions have an x-intercept: 1 for f(x), 5 for g(x)
so only the second choice is correct

Solve for the roots in simplest form using the quadratic formula:
4x^2 -28x= -53
Answer:
x = (28 +- root -64) / (8)
Step-by-step explanation:
4x^2 -28x= -53 = 0
x = [-(-28)+- root (-28)^2 - 4 * 4 * 53] / 2 *4
x = (28 +- root 784 - 848) / (8)
x = (28 +- root -64) / (8)

Your pay rate would be $7 per hour
Your friend's rate is $9 per hour
Step-by-step explanation:
To get the answer for your pay rate you'll have to divide 56/8 and then you'd get your number 7, so you get $7 dollars per hour.
To get the number for your friends pay rate you'd also do the same thing, divide. 36/4 gives you the number 9, so your friend gets $9 dollars per hour.

Suppose you are ordering a calzone from D.P. Dough. You want 4 distinct toppings, chosen from their list of 8 vegetarian toppings. How many choices do you have for your calzone
Answer:
1680
Step-by-step explanation:
Number of distinct Toppings wanted = 4
Total number of vegetarian topping = 8
To choose 4 distinct toppings from a total of 8
Using permutation :
nPr : n! (n - r)!
8P4 = 8! / 4!
8P4 = (8*7*6*5)
8P4 = 1680
Melanie earns $7 per hour when she
baby-sits. An equation for this relation
is w = 7h, where h represents the
number of hours and w represents
Melanie's wage in dollars.
a) Use the equation to create a table
of values.
b) In one week, Melanie earned $105.
How many hours did she baby-sit?
c) In one month, Melanie baby-sat for
24 h. How much did she earn
from baby-sitting in that month
Answer:
A) We know that she make $7 per hour, with this we can make a table:
1hr | $7
2hr | $14
3hr | $21
etc...
B) If in one week she earns $105 and 1w = 7h (1hr = $7) holds true, that means that we have to divide 105 by 7 which gives us 15hrs
C) If she baby-sat for 24hrs, we just have to multiply that by 7 and we get $168

O y=4+x
O y=1/4x
Oy=4 - x
Answer:
Step-by-step explanation: It’s C thank me later
The equation produces the values in the table is y = x/4
What is an equation?Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.
For example, 2x – 5 = 13.
Given is table (attached) we need to determine an equation that produces the values in the table,
So, seeing the value it is much that the value of x are the 4 times of the values of y,
So, we can write,
4y = x
or, y = x/4
