Explanation:
Difference indicates subtraction:
The difference of a number and
9
is
(
x
−
9
)
Twice the difference means
2
(
x
−
9
)
We know that the answer to this is
2
, so as an equation:
2
(
x
−
9
)
=
2
If you solve it we would have:
x
−
9
=
1
←
÷
2
x
=
1
+
9
x
=
10
The difference between
10
and
9
is
1
and twice
1
is
2
.
The number is correct.
Note that written as:
The difference of twice a number and
9
would have a different expression. This would be
2
x
−
9

An instructor announces that 2 out of 5 test
questions will be essay-type questions. If the
test has 20 questions, how many are essay-type
questions?
Answer:
8 essay-type questions
Step-by-step explanation:
This is the answer because:
1) 2 out of 5 is the same as 2/5
2) Next, we have to get 2/5's denominator to equal 20.
2 x 4/5 x 4 = 8/20
3) 8/20 means that 8 of the test questions are essay-type
Hope this helps!

Earlier this month, 69% Californians voted 'yes' on Measure H: a sales tax measure to fund homeless services and prevention.what is the probability that in a sample of S0 Californians, more than 66% will vote 'yes' on Measure H. Find the 20th percentile for the above distribution of sample proportions. Le Find Pro ?) = 0.20. O
A 0.74
B 0.64
C 0.59
Answer:
0.64 ( B )
Step-by-step explanation:
Find the 20th percentile i.e. P ( p ≤ ? ) = 0.20
To determine the 20th percentile for the above distribution we apply this relationship
[tex]Z = \frac{p - P}{\sqrt{\frac{P(1-P )}{N} } }[/tex] ------------- ( 1 )
Given :The Z -score of 20th percentile = - 0.84
P = 0.69
N = 50 Californians
p = ?
Insert the given data into equation 1, equation 1 becomes
p - 0.69 = ( -0.84 )( 0.0654 )
hence p = 0.64
Find the linear approximation of the function f(x) = √4-x at a = 0 and use it to approximate the numbers √3.9 and √3.99 ?
Answer:
1.9975
Step-by-step explanation:
The computation of the linear approximation of the given function is shown below:
L(x) = 2 - 1 ÷ 4(x)
As we are looking for √3.9
So here
x = 0.1
So
= 4 - 0.1
= 3.9
Now
L(0.1) = f(3.9) = 2 - (0.1 ÷ 4)
= 1.975
now
substitute the x = 0.01
Then
L(0.01) = f(3.99) = 2 - (0.01 ÷ 4)
= 1.9975
We simply applied the above equations

Vershaun walked 5.5 miles to his friend's house. He left his house at 9 a.m. and arrived at his friend's house at 11 a.m. What was his walking rate in miles per hour?
Answer:
2.75 mph
Step-by-step explanation:
S = speed
D = distance
T = time
The formula is: S = D/T
S = 5.5/2
(11:00am - 9:00am = 2 hours)
S = 2.75 mph
5x+(-4)=7x-5 show step by step
Answer:
Step-by-step explanation:
First you have to add 4 to both sides--5x-4+4=7x-5+4
Now you have 5x=7x-1
Next you subtract 7x from both sides--5x-7x=7x-1-7x
Next you simplyfiy -2x=-1
Now divide by -2 on each side--2x/2=-1/2
So your answer should be--x=1/2

1. In 2015, there were 3050 drug-related deaths, of which 2950 involved opioids. What percent of the deaths were due to opioids
Answer:
The percentage of the deaths due to opioids is 96.72%
Step-by-step explanation:
Given;
total number of drug related death cases in 2015, T = 3050 deaths
number of deaths due to opioids, n = 2950 deaths
The percentage of the deaths due to opioids is given by;
death percent due to opioids = 2950 / 3050
death percent due to opioids = 0.9672
death percent due to opioids = 0.9672 x 100 = 96.72%
Therefore, the percentage of the deaths due to opioids is 96.72%
Use the Distributive Property to find the product,
28 x 47 = 28 x (40 + 7)
28 x 47 = (28 x 40) + (28 x 7)
28 x 47 = (20 + 8) + (20 + 8) %
28 x 47 = (20 %) + (8 %) + ( 20 ) +(8 x
28 x 47 = + + +

(Part 1)What is the combined area of the two right triangles? A. 12 B. 18 C. 24 D.36
(Part 2) Whick expression gives the area of the parallelogram A. (14x6-24) square units B.(14x6-18) square units C.(8x6+36) swuare units
D. (8x6+12) square units
Answer:
Part 1: D. 36
Part 2: C. (8*6 + 36) square units
Step-by-step explanation:
Part 1:
Area of a triangle = ½*base*height
The two triangles has the same height and base.
Height = 6,
Base = 6
Combined area of the two right angles = 2(½*base*height)
= 2(½*6*6)
= (6*6)
Combined area = 36 square units
Part 2:
The are of the parallelogram = area of the rectangle + the combined are of the two right triangles
The rectangle has:
length = 14 - 6 = 8
Width = 6
Area of rectangle = length * width = 8*6
Combined area of the two right triangles = 36
Therefore, the expression of the area of the parallelogram = (8*6 + 36) square units
