Answer:
The wife IQ is 103 when the husband IQ is 100.
Step-by-step explanation:
The given equation of the regression line is y = -11 + 1.14x, where x represents the IQ score of the husband.
If the husband IQ is 100 the the wife IQ is
y = -11 + 1.14x,
y = -11 + 1.14(100)
y = -11 + 114
y = 103

what is the value of a when we rewrite 8^x as a^-x/9
Answer:
[tex]a = \frac{1}{134217728}[/tex]
Step-by-step explanation:
Given
[tex]8^x = a^{-x/9}[/tex]
Required
Find a
Take log of both sides
[tex]log(8^x) = log(a^{-x/9})[/tex]
Apply law of logarithm
[tex]x\ log(8) = (-x/9) log(a)[/tex]
Divide both sides by a
[tex]log(8) = -\frac{1}{9} log(a)[/tex]
Multiply both sides by -9
[tex]-9\ log(8) = log(a)[/tex]
Apply law of logarithm
[tex]log(8^{-9}) = log(a)[/tex]
Cancel out log
[tex]8^{-9} = a[/tex]
Rewrite as:
[tex]a = 8^{-9}[/tex]
Apply law of indices
[tex]a = \frac{1}{8^9}[/tex]
[tex]a = \frac{1}{134217728}[/tex]

Answer:
B or D is correct i think it's b most likey
Step-by-step explanation:
An agricultural scientist collected data to study the relationship between the amount of nitrogen added to a cornfield and the number of bushels of
com produced. This is the regression line of the data, where y is measured in bushels of corn and is measured in pounds of nitrogen
y=0.43x + 28.5
What is the meaning of the slope of the regression line?
O A For every 0.43 pounds of nitrogen added to the field, the amount of corn yielded increases by 28.5 bushels.
OB. For every 1 pound of nitrogen added to the field, the amount of corn yielded increases by 0.43 bushels
OC. For every 1 pound of nitrogen added to the field, the amount of corn yielded increases by 28.5 bushels
OD. For every 28.5 pounds of nitrogen added to the field, the amount of com yielded increases by 0.43 bushels.

Answer:
13 units is the answer.
Step-by-step explanation:
points (8,-4) and (3,8)
We can rewrite the Pythagorean theorem as,
[tex]d=\sqrt{(x_2 - x_1)^2+(y_2-y_1)^2} \\\\d= \sqrt{(3-8)^2 + (8-(-4))^2} \\\\d=\sqrt{(-5)^2 + (12)^2} \\\\d=\sqrt{25 + 144} \\\\d=\sqrt{169} \\\\d=13\\\\[/tex]
∴ distance between 2 points (8,-4) and (3,8) = 13 units.
Find the surface area of a cylinder with a diameter of 8
yards and a height of 9 yards.
Answer:
a=326.76 yd^2
Step-by-step explanation:
a= 2pi(d/2)h+2pi(d/2)^2=2pi(8/2)9+2pi(8/2)^2= 326.72564yd^2
The zeroes of the function are
-2 and 0
0 and 4
-2, 0, and 4
1. x=-2, x=0
So, the equation in factored form would be x(x+2)=0.
2. x=0, x=4
So, the equation in factored form would be x(x-4)=0.
3. x=-2, x=0, x=4
So, the equation in factored form would be x(x+2)(x-4)=0.
Answer:
-2, 0, and 4

Answer: 26
Step-by-step explanation:
Angles on a straight line add to 180 degrees, so:
[tex]4x+4+4x-32=180\\\\8x-28=180\\\\8x=208\\\\x=26[/tex]
The value of x is 26.
What is Straight line?A straight line is an endless one-dimensional figure that has no width
An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint.
The angles add up to 180 degrees in a straight line.
The two angles are 4x+4 and 4x-32
4x+4+4x-32=180
Add the like terms
8x-28=180
Add 28 on both sides
8x=180+28
8x=208
Divide both sides by 8
x=26
Hence, the value of x is 26.

Find the length of each trapezoid.
Answer:
EF = 27
Step-by-step explanation:
(x + 34)/2 = 2x - 13
x+ 34 = 4x - 26
3x = 60
x = 20
EF = 2(20) -13 = 27
Answer:
11. EF = 27
Step-by-step explanation:
11.
Median of a trapezoid:
2x - 13 = 20 + x + 14
2
2(2x - 13) = 20 + x + 14
4x - 26 = 34 + x
4x - x = 34 + 26
3x = 60
x = 20
EF = 2x - 13
EF = 2(20) - 13
EF = 40 - 13
EF = 27

A football stadium holds 5000 people.
On a match day z of the stadium is full.
40% of the children are girls.
The ratio of adults to children is 2:3
How many of the children attending are boys?
Can someone plz help me with this
Answer:
1000 children
Step-by-step explanation:
Find the total units of adults and children = 2 + 3 = 5
5 units = 5000
1 unit = 5000 ÷ 5 = 1000
100% ÷ 5 units = 20% each unit
3 units = 20% x 3 = 60%
Since we all know that 60% of the people are children and 40% of the children are girls...
60 - 40 = 20%
20% = 1000
