Answer:
EF = 36
Step-by-step explanation:
On a rhombus, all sides are equal because its a parallelogram so,
EF = FG
we first have to find what x equals so . . .
let's plug in the numbers
4x - 20 = 2x + 8
Now we combine like terms
we add 20 to both sides
so now it would be
4x = 2x +28
Now we subtract 2x from both sides because we want x by itself
this would equal
2x = 28
now we divide two from both sides this equals
x = 14
now we insert the numbers in the equation
4 x 14 - 20 = 36

Chris makes a smoothie for breakfast every day. When he makes smoothies with bananas, the distribution of calories is skewed right with a mean of 248.6 and a standard deviation of 39.1. His berry smoothies have a distribution of calories that is approximately Normal with a mean of 279.1 calories and a standard deviation of 60.8. Random samples of 35 of each type of smoothie are selected. What is the probability of the banana smoothies having fewer mean calories than the berry smoothies?

Two customers took out car loans from a bank.
Robert took out a 4-year loan for $30,000 and paid 4.9% annual simple interest.
Susan took out a 6-year loan for $30,000 and paid 4.5% annual simple interest.
What is the difference between the amounts of interest Robert and Susan paid for their car loans?
Enter your answer in the box.
$ { }
Answer:
Susan pays $2220 more interest than Robert
Step-by-step explanation:
Interest = principle times rate times the time
I = PRT
Robert: I = 30000(.049)(4) = $5880
Susan: I = 30000(.045)(6) = $8100
8100 - 5880 = $2220

helpp i am really bad with math
Answer:
1. 4y-12
2. c
For #1 you distribute the 4 to the y and the 3. 4 times 3 equals 12.
For #2 you factor out the 3 and you get 3(5x+1)
Answer:
4y-12
Step-by-step explanation:
Multiply the outside number by the numbers in the bracket.
Example:4×y=4y Because y=1
4×3=12
2.Answer C
3(5x+1)
3×5x=15x
3×1=1
Which is equivalent to 3(5x+3)

factor the following completely 6i^2−7i−3, and 2i^2−11i+14
Answer:
-7i - 9
-11i + 12
Step-by-step explanation:
i stands for imaginary number, in which i² = -1
6i² = 6 * -1 = -6
-6 - 7i - 3
Combine like terms:
-6 - 3 = -9
-7i - 9
2i^2 = 2 * -1 = -2
Combine like terms:
-11i + 14 - 2
-11i + 12

Enter the value for X that makes the equation 1/2 (4x-8) + 3x = 36 true
Answer:
x = 8Step-by-step explanation:
Solve for x:
1/2 (4x - 8) + 3x = 362x - 4 + 3x = 365x - 4 = 365x = 40x = 40/5x = 8Answer:
1/2 (4x-8) + 3x =36
(4x-8+3x×2)/2=36
(4x+6x-8)=36×2

Which properties of logarithms help you simplify log 200 + log 5 - log 100? (Select all that apply.)
(Refer to picture)
Answer:quotient property
Product property
Step-by-step explanation:
Just took the test
Product and quotient properties are required to solve or simplify the log 200 + log 5 - log 100
What are Logarithms?A logarithm is the power to which a number must be raised in order to get some other number
The given expression is
log 200+log 5-log 100.
The sum property of logarithms is
log a+ log b= log ab
This is also a product property.
log 1000-log 100
Now we use quotient property
log 1000/100
log 10
Hence, product and quotient properties are required to solve or simplify the log 200 + log 5 - log 100

Find the marginal distribution of gender in counts.
Complete question :
Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.
Millitary status _________ female ____ Male
In armed forces _________ 28 _______ 59
Millitary dependent ______ 928 ______ 781
Civilian _______________ 26393 ___27330
Answer:
Male = 0.4193
Female = 0.5087
Step-by-step explanation:
To obtain the marginal distribution of gender :
Total number of civilians (male + female)
(26393 + 27330) = 53,723
Male :
P(male) = number of male / total
P(male) = 26393 / 53,723 = 0.4912793
P(Female) = number of Female / total
P(Female) = 27330 / 53,723 = 0.5087206

Find the measures of the numbered angles in each rhombus
Answer:
2=41 1=49 3=49
Step-by-step explanation:
Angle 2 = 41 because it is directly across the given angle.
Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.
41+41=82
180-82=98
98 / 2 = 49
Angles and 3 both equal 49
Answer:
2=41°(Alternate Interior angles)
1=41°(diagonal of rhombus bisects the interior angles)
3=49°(180-82/2)

You roll a fair 6-sided die.
What is P(roll an even number)?
Answer: [tex]\frac{3}{6}[/tex] or 0.5
Step-by-step explanation:
It has 6 sides, {1,2,3,4,5}. So the total number of cases is 6.
Even number includes {2,4,6}. The sample space of rolling an even is 3.
The probability of rolling an even number formula is:
P(Rollinganevennumber)= [tex]\frac{Number of cases in the sample space}{Total number of cases}[/tex]
The probability of an even number is [tex]\frac{3}{6}[/tex] or 0.5

Y/-3=1/6 HELP PLEASE
Answer:
y = -0.5
Step-by-step explanation:
Since 6 can be multiplied to -3, we can make an equation to make 6 turn into -3
6 ÷ -2 = -3
So since we did that with 6, the denominator, we do the same with 1, the numerator
1 ÷ -2 = -0.5
So the new numerator is -0.5, and the new denominator is -3
And the two fractions are the same

What is an area circle?The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.
Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles
Thus, the requried range of the radio station is given as 1256 square miles.

A ball is thrown into the air with a speed of 32 feet per second. The function h=32t - 16t^2 models the height of the ball after t seconds. How many seconds does it take for the ball to reach its maximum height?
Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :
[tex]h=32t - 16t^2[/tex]
We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0
[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]
So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
