Is the proportion of the female population age 60 or older in country A greater than the proportion of the female proportion age 6 or older in country B
Answer:
Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.
Step-by-step explanation:
From. The plot given :
We could approximate the proportion of females older than 60 as follows _
COUNTRY A :
60 - 69 = 0.105
70 - 79 = 0.065
80 - 89 = 0.038
90+ = 0.01
Total = About 0.218
COUNTRY B :
60 - 69 = 0.14
70 - 79 = 0.11
80 - 89 = 0.07
90+ = 0.02
Total = About 0.34
From the estimated proportion, the proportion of females on country B is more than the proportion in country A.
For each expression, write an equivalent expression that uses only addition: a. 20 - 9 + 8 - 7 b. 4x - 7y - 5z + 6 c. -3x - 8y - 4 - 8/7z
Answer:
a. =11+ 1
b. =4x+ (-7y) + (-5z) +6
c. (-3x) + (-8y) +(-4)+(-8/7z)
Step-by-step explanation:
a. 20 - 9 + 8 -7
=11+ 1 ( this is obtained by solving)
b. 4x - 7y - 5z + 6
=4x+ (-7y) + (-5z) +6
We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.
c. -3x - 8y - 4 - 8/7z
-[ 3x+8y+4+8/7z]
or
(-3x) + (-8y) +(-4) +(-8/7z)
The minus sign is taken as common leaving the expression with the plus only.
It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.
The expressions are a sum after the negative sign is marked with the terms. It shows that the negative terms are being added.

find the value of x. (picture)
Answer:
x = 23
Step-by-step explanation:
Remember, angles in a triangle add up to equal 180
That being said we can create an equation to solve for x
180 = 110 + 35 + x + 12
now we solve for x
step 1: combine like terms
110 + 35 + 12 = 157
now we have 180 = 157 + x
step 2 subtract 157 from each side
180 - 157 = 23
157 - 157 cancels out
we're left with x = 23

The national interest rate for savings accounts is 0.04%. I put $2,000 in my savings account for 40 years. How much interest will I earn?
Answer: $32.25
Step-by-step explanation:
Assuming this is compound interest, the value of the investment after a period of time can be calculated with the future value formula:
Value = Investment * ( 1 + rate) ^ no. of periods
Value ₄₀ = 2,000 * ( 1 + 0.04%)⁴⁰
Value ₄₀ = $2,032.25
Interest earned = Value at 40 years - Initial investment
= 2,032.25 - 2,000
= $32.25
Y=190(1.471)^x determine the percentage of increase or decrease
Given:
The exponential function is:
[tex]y=190(1.471)^x[/tex]
To find:
The percentage of increase or decrease.
Solution:
The general exponential function is:
[tex]y=a(1+r)^x[/tex] ...(i)
Where, a is the initial value,t is the time period, r is the rate of increase if [tex]r>0[/tex] and r is the rate of decrease if [tex]r<0[/tex].
We have,
[tex]y=190(1.471)^x[/tex]
It can be written as:
[tex]y=190(1+0.471)^x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]r=0.471[/tex]
Since [tex]r>0[/tex], therefore the given function is an increasing function.
[tex]r\%=0.471\times 100[/tex]
[tex]r\%=47.1\%[/tex]
Therefore, the percentage of increase is 47.1%.

What is the equation in slope-intercept form of the line that crosses the x-axis at 21 and is perpendicular to the line represented by y = 7/2x-13
Given:
A line is perpendicular to the line [tex]y=\dfrac{7}{2}x-13[/tex].
The line passes through the x-axis at 21.
To find:
The equation of the line in slope intercept form.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is the slope and b is the y-intercept.
The given line is:
[tex]y=\dfrac{7}{2}x-13[/tex]
So, the slope of this line is [tex]\dfrac{7}{2}[/tex].
The product of slopes of two perpendicular lines is -1.
Let m be the slope of required line. Then the slope of the required line is:
[tex]m\times \dfrac{7}{2}=-1[/tex]
[tex]m=-\dfrac{2}{7}[/tex]
The line passes through the x-axis at 21. It means the line passes through the point (21,0). So, the equation of the line is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-0=-\dfrac{2}{7}(x-21)[/tex]
[tex]y=-\dfrac{2}{7}(x)-\dfrac{2}{7}(-21)[/tex]
[tex]y=-\dfrac{2}{7}x+6[/tex]
Therefore, the equation of the required line is [tex]y=-\dfrac{2}{7}x+6[/tex].

(PLEASE HELP) What is the area?
Answer:
The area is 2,000 cm2
Step-by-step explanation:
The answer is that because Area is when you multiply the length times the width ( l x w ). The length is 40 cm and the width is 50 cm and when you multiply them, you will get 2,000 cm2.

y varies directly with x. If y = 75 when x =25, find x when y = 25.
Answer:
25/3
Step-by-step explanation:
y = kx
75 = k * 25
k = 75/25 = 3
y = 3x
25 = 3x
x = 25/3
The value of x when y = 25 is 25/3.
what is proportion?A proportion is an equation in which two ratios are set equal to each other.
Given : y=75 and x= 25
So,
75/25= 25/x
75*x= 25*25
75*x=625
x= 625/75
x= 25/3
Hence, the value of x when y =25 is 25/3.

Which of the following sets of numbers could not represent the three sides of a right
triangle?
{20, 48,52}
{40, 75, 85}
{14, 47,50}
{13, 84, 85}
Answer:
{14, 47, 50}
Step-by-step explanation:
The three sides of a right triangle must satisfy
a² + b² = c², known as the Pythagorean Theorem. So let's put the pairs into the theorem.
20, 48, 52
a² + b² = c²
20² + 48² = 52²
400 + 2304 = 2704
2704 = 2704
20, 48, and 52 represent the three sides of a right triangle.
40, 75, 85
a² + b² = c²
40² + 75² = 85²
1600 + 5625 = 7225
7225 = 7225
40, 75, and 85 represent the three sides of a right triangle.
14, 47, 50
a² + b² = c²
14² + 47² = 50²
196 + 2209 = 2500
2405 ≠ 2500
14, 47, and 50 do NOT represent the three sides of a right triangle.
13, 84, 85
a² + b² = c²
13² + 84² = 85²
169 + 7056 = 7225
7225 = 7225
13, 84, and 85 represent the sides of a right triangle.
14, 47, and 50 do NOT represent the three sides of a right triangle, therefore making it your answer.
