Which category in the table shows the least portion of the class?
Answers
Answer:
The people who said Yes to having a pet in their home is greater
Step-by-step explanation:
We are asked to compare 18% and 14/25. Let's get them to their lowest common denominator:
18% = 18/100
14/25 * 4 = 56/100
18/100 is clearly much less than 56/100. If you don't want to write all this out, you can also eyeball that 14/25 is over half, whereas 18% is not close to half.

What is the value of x in the figure below?
Answers
Answer:
x = 25°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
The given triangle is a right triangle which means one of its angle has a measure of 90°
since thd other angle is given as 65 to calculate x we just add the given measures and subtract it from 180
90° + 65 + x = 180
155 + x = 180 subtract 155 from both sides
x = 25°

First, calculate the slope (m)
Considering
[tex](x_1,y1) = (12,60)[/tex]
[tex](x_2,y_2) = (15,20)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{20-16}{15-12}[/tex]
[tex]m = \frac{4}{3}[/tex]
Considering:
[tex](x_1,y_1) = (15,20)[/tex]
[tex](x_2,y_2) = (24,y)[/tex]
The slope is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{y - 20}{24 - 15}[/tex]
[tex]m = \frac{y - 20}{9}[/tex]
Recall that: [tex]m = \frac{4}{3}[/tex]
So:
[tex]\frac{4}{3} = \frac{y - 20}{9}[/tex]
Multiply through by 9
[tex]3*4 = y - 20[/tex]
[tex]y = 20 + 3 * 4[/tex]
[tex]y = 32[/tex]

\small -7x=x^2+12
Answers
Answer:
read explanation
Step-by-step explanation:
this is a quadratic equation
first, move the 7x over to the other side so that we have 0 on one side
x^2+7x+12=0
now, we can factor
turn 7x into 3x and 4x, so x^2+3x+4x+12=0
you can turn x^2+3x into x(x+3) and 4x+12 into 4(x+3)
so, our new equation is x(x+3)+4(x+3)=0
that can be turned into (x+4)(x+3)=0 via the distributive property
so, either x+4 or x+3 has to be equal to 0
so, x is either -4 or -3

ramu and ravi borrowed rs 8000
Answers
Answer: Rs. 11,520
Step-by-step explanation:
As the method of compounding is not stated, the default of simple interest will be used.
Simple interest is a fixed amount that is paid over the course of the loan and is based on the original amount borrowed.
Formula is:
Amount owed = Amount borrowed * ( 1 + rate * time)
= 8,000 * ( 1 + 8% * 5.5 years)
= 8,000 * 1.44
= rs 11,520

What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The measure of the arc FE is 146 degrees.
Measure ED is 90 degrees.
To find the measure of the arc EDF we have to find the measure of DF.
146+90+x=360
236+x=360
Subtract 236 from both sides
x=360-236
x=124
Now let us find the arc measure EDF =Measure of ED + Measure of DF
=90+124
=214 degrees
Hence, the measure of the arc is 214 degrees

b=base of triangle a=altitude of triangle h=height of prism
Doing [tex]\frac{1}{2}(b*a)[/tex] is essentially finding the area of the triangle and after multiplying by h will give you the volume of the triangular prism.

find the surface area of a cylinder with the height of 10 inches and a base diameter of 6 in
Answers
Answer:
339.24
Step-by-step explanation:
To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2
The radius is half the diameter do r=3
3.14(3)^2 should give you about 28.27.
This is the area of the top and bottom of the cylinder.
Now, do 28.27x10=282.7 to find the height surface area.
282.7+28.27+28.27=Surface area.
SA= about 339.24

A large school district is considering implementing a program that, if successful, would improve the reading scores of its students by 10 points. The current reading scores for the district are normally distributed with a mean of 25 and a standard deviation of 8. The administrators decide to test the new program in one school of 200 students. What is the standard deviation of the comparison distribution
Answers
Answer:
The standard deviation of the comparison distribution is 0.5657.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
In this question:
Standard deviation of the population is 8, sample of 200. So
[tex]s = \frac{8}{\sqrt{200}} = 0.5657[/tex]
The standard deviation of the comparison distribution is 0.5657.
