Answer:
x = -1.5
Step-by-step explanation:
3x-1= 7x+5
Subtract 3x from each side
3x-3x-1= 7x-3x+5
-1 = 4x+5
Subtract 5 from each side
-1-5 = 4x+5-5

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 34 hours and the median is 30.2 hours. Twenty-four of the families in the sample turned on the television for 19 hours or less for the week. The 8th percentile of the data is 19 hours. Step 4 of 5 : What is the value of the 50th percentile
Answers
Answer: The value of the 50th percentile is 30.2 hours.
Step-by-step explanation:
We are given:
Mean of the data watching television by 24 families = 34 hours
Median of the data watching television by 24 families = 30.2 hours
8th percentile of the data = 19 hours
The median of data is the value that divides the data into two equal halves.
This means that the median will represent the 50th percentile of data.
Thus, the value of the 50th percentile is 30.2 hours.

Answers
Answer:
3.75cm 44.16cm²
20cm 314cm²
42cm 1384.74cm²
Step-by-step explanation:
Area of a circle = πr²
Where : = π = pi = 3.14
R = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
16. Radius = 7.5 / 2 = 3.75
Area = 3.14 x 3.75² = 44.16
17. Diameter = 10 x 2 = 20
Area = 10² x 3.14 = 314
18. Diameter = 21 x 2 = 42
Area = 21² x 3.14 = 1384.74
Karen purchased 3 gallons of yellow paint and 4 gallons on blue paint from the hardware store. The total cost was $105. Yellow
paint and blue paint sell for the same price per gallon. Which THREE statements are correct?
Answers
Answer:
In order to answer this properly, I would need to see the choices. However, I can tell you that:
-Each gallon of paint cost $15
-Karen spent $45 on yellow paint
-Karen spent $60 on blue paint
Step-by-step explanation:
Karen bought a total of 7 cans of paint, all the same price.
105/7=15.
15*3=45 (yellow paint)
15*3=60 (blue paint)

Someone help me on this percent question
Answers
Answer: 6%
Hope it helps :)
Step-by-step explanation:
Price of mixer = 45.00$
Price of mixer with tax = 47.70
Tax added to the price of mixer = 45 - 47.70
= 2.70$
Percentage of Tax added to the price of mixer
= 2.70 = P multiplied by 45
(divide 2.70 by 45 and 45 by 45 as well)
= 0.06 = P
(we have to now convert the decimal to a percentage)
= 0.06 multiplied by 100 = P
6% = P

Answer:
x = {-4.4, +2.9}
Step-by-step explanation:
We assume you want to solve ...
2x^2 +3x -41 = -15
Adding 41 and factoring out the leading coefficient gives ...
2(x^2 +3/2x) = 26
Dividing by 2 makes it ...
x^2 +3/2x = 13
We can add the square of half the x-coefficient to "complete the square."
x^2 +3/2x +(3/4)^2 = 13 +(3/4)^2
(x +3/4)^2 = 13.5625 . . . . write the left side as a square
x +3/4 = ±√13.5625 . . . . . take the square root
x = -0.75 ±3.683 = {-4.433, +2.933} . . . . subtract 3/4 and evaluate
The solutions are approximately x = -4.4 and x = 2.9.

Answers
Answer:
Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%.
Step-by-step explanation:
Given that Elena receives $ 131 per year in simple interest from three investments totaling $ 3000, and part is invested at 3%, part at 4% and part at 5%, and there is $ 1000 more invested at 5% than at 4%, to find the amount invested at each rate, the following calculations must be performed:
1500 x 0.05 + 500 x 0.04 + 1000 x 0.03 = 75 + 20 + 30 = 125
1600 x 0.05 + 600 x 0.04 + 800 x 0.03 = 80 + 24 + 24 = 128
1700 x 0.05 + 700 x 0.04 + 600 x 0.03 = 85 + 28 + 18 = 131
Therefore, Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%

The circumference of a circle is 19 pi m. What is the area, in square meters? Express your answer in terms of pi
Answers
Answer:
90.25πm^2
Step-by-step explanation:
circumference = 2 pie r
then , 19 pie meter = 2 pie r
so radius r = 19 /2 m
therefore ,
area of circle = pie r ^ 2
= 90.25 pie meter square
Answer:
circle circumference formula is 2 pi R
and area of circle pi R ²
19 pi is 2×9.5×pi
so the radius is 9.5
and area is pi 9.5² m² = 90,25 pi m²
Due to the heavy rains, all pallets of blocks have become wet and the weight of each block has altered. It is desired to estimate the average weight of the blocks thus wet. For this, a sample of 15 blocks is selected and the following weights are recorded in kilograms: 45.8, 43.9, 46.2, 48.5, 47.2, 45.8, 49.1, 43.9, 47.6, 42.8, 46.5, 44.9, 46.8, 45.8 and 44.6; Estimate µ, the average weight of all pallets of blocks, and determine a bound for the estimation error.
Answers
Answer:
To find the estimated value we add all of them together then divide it by the amount of them
45.8+43.9+46.2+48.5+47.2+45.8+49.1+43.9+47.6+42.8+46.5+44.9+46.8+45.8 +44.6=689.4
now we divide it by 15 since there is 15 blocks so
689.4 divided by 15=45.96
so the average weight is 45.96

2) 8 , 11, 11.3
Step-by-step explanation:
1) To figure out the inverse of a function , first change the F(x) to y
y = [tex]\frac{x+1}{2}[/tex]
Then switch the x and y
x = [tex]\frac{y+1}{2}[/tex]
Solve for y. Multiply by 2 both sides. Subtract 1 from both sides.
2) Use distance formula : d = [tex]\sqrt{(x_{2}-x_{1}) ^{2} + (y_{2}-y_1)^{2} }[/tex]
the first two are easy because the same x value. so just calculate Δy

The volume of this sphere is equal to [tex]2929\frac{1}{3} \pi ft^{3}[/tex]
Step-by-step explanation:
In order to solve this question, we need to know the formula for the volume of a sphere which is...
[tex]V = \frac{4}{3}\pi r^{3}[/tex] ("V" is the volume of the sphere, and "r" is the radius of the sphere)
Now we have to substitute the values that we already know into the formula, and we will get that...
[tex]V = \frac{4}{3}\pi r^{3}\\\\V = \frac{4}{3} \pi (13ft)^{3} \\\\V = \frac{4}{3} \pi (2,197ft^{3} )\\\\V = 2,929\frac{1}{3} \pi ft^{3}[/tex]
Therefore, the volume of this sphere is equal to [tex]2929\frac{1}{3} \pi ft^{3}[/tex]

Answer:
(c) [-2, 7]
Step-by-step explanation:
We can solve the inequality for an expression in x.
2|5 -2x| -3 ≤ 15
2|5 -2x| ≤ 18 . . . . . . add 3
|5 -2x| ≤ 9 . . . . . . . . divide by 2
We prefer a positive coefficient of x, so we'll multiply inside the absolute value by -1. This does not change the absolute value. (|-1| = |1|, for example)
|2x -5| ≤ 9
Now, we can "unfold" this to get the compound inequality ...
-9 ≤ 2x -5 ≤ 9
-4 ≤ 2x ≤ 14 . . . . . add 5
-2 ≤ x ≤ 7 . . . . . . . divide by 2
The solution interval is [-2, 7].

The graph shows the equation of the given form f(x) ≤ c converted to the form f(x)-c ≤ 0. The graphing calculator highlights x-intercepts easily, so we take advantage of that to show the solution interval bounds. The graph is less than zero between the bounds.
