Find the distance between the points.
(−3,− 8), (6, – 8)
The distance is
To calculate the distance between two points:
We apply the following formula:
d = √(x₂ - x₁)² + (y₂ - y₁)²
The points are:
(x₁,y₁) = -3, -8(x₂,y₂) = 6, -8We substitute data and solve:
[tex]\bf{d=\sqrt{(6-(-3))^2+(-8-8(-8))^2 } }\\ \\ \bf{ d=\sqrt{9^2+0^2}=\sqrt{81+0} }\\ \\ \bf{d=\sqrt{81}=9 }[/tex]
The distance between the points (−3,− 8), (6, – 8) is 9.

Answer: 39.5 ft^2
Step-by-step explanation:
1. Find the area of the rectangle using the formula length * width
8 ft * 4 ft = 32 ft2. Find the area of one of the triangles (the top one) using the formula 1/2(b*h)
2 ft * 3 ft * 0.5 = 3 ft3. Find the area of the other triangle (the bottom one) using the formula 1/2(b*h)
3 ft * 3 ft * 0.5 = 4.5 ft4. Add 'em all up to get the total area
32 ft + 3 ft + 4.5 ft = 39.5 ft ^2What is the spread of Cassandra’s grades?

Ann 's car can go 132 miles on 4 gallons of gas. During a drive last weekend, Ann used 5 gallons of gas. How far did she drive? Use pencil and paper. Explain how the problem changes if you were given the distance Ann drove last weekend instead of how much gas she used.
Answer:
Ann traveled 165 miles on 5 gallons of gas
Step-by-step explanation:
First we must know how many miles are in a gallon (in this situation). Last weekend Ann drove 132 miles with 4 gallons of gas, we can divide to find out how many miles she drove on 1 gallon. 132/4 = 33. This means Ann drove 33 miles on 1 gallon of gas. To get your answer, simply multiply 5 and 33. 5 times 33 = 165.
"-12<-3x-15" less than or equal to 36
Answer:
-17 ≤ x < 1
Step-by-step explanation:
-12 < -3x - 15 ≤ 36
Add 15 to all 3 "sides."
-12 + 15 < -3x - 15 + 15 ≤ 36 + 15
3 < -3x ≤ 51
Divide all 3 "sides" by -3. Remember that when you multiply or divide an inequality by a negative number, you much change the direction of the inequality sign.
3/(-3) > -3x/(-3) ≥ 51/(-3)
-1 > x ≥ -17
Rewrite in standard order.
-17 ≤ x < 1

Circle Review Worksheet
Please help
Answer/Step-by-step explanation:
Recall: circumference of a circle, C = πd or C = 2πr
Where d = diameter
Radius (r) = ½ of diameter
1. Radius (r) = 3 cm
Diameter (d) = 2(3) = 6 cm
Circumference = πd = π*6
C = 18.8495559 ≈ 18.8 cm (nearest tenth)
2. Radius (r) = 6 in.
Diameter (d) = 2(6) = 12 in.
Circumference = πd = π*12
C = 37.6991118 ≈ 37.7 in. (nearest tenth)
3. Radius (r) = 9 mm
Diameter (d) = 2(9) = 18 mm
Circumference = πd = π*18
C = 56.5486678 ≈ 56.5 mm (nearest tenth)
4. Radius (r) = ½(4.8) = 2.4 cm
Diameter (d) = 4.8 cm
Circumference = πd = π*4.8
C = 15.0796447 ≈ 15.1 cm (nearest tenth)
5. Radius (r) = ½(7) = 3.5 cm
Diameter (d) = 7 cm
Circumference = πd = π*7
C = 21.9911486 ≈ 22.0 cm (nearest tenth)
6. Radius (r) = ½(14) = 7 cm
Diameter (d) = 14 cm
Circumference = πd = π*14
C = 43.9822972 ≈ 44.0 cm (nearest tenth)

Step-by-step explanation:
A recipe for 8 pancakes needs the following:
1 1/4 cups of milk
1 1/2 cups of flour
1 egg
Maria has these ingredients.
1 quart of milk
8 cups of flour
12 eggs
How many more cups of milk does Maria need to make 40 pancakes in total?
Answer:
2 1/4 cups
Step-by-step explanation:
the first step is to determine how many cups would be needed for 1 pancake
1 1/4 ÷ 8
5/4 x 1/8 = 5/32 cups
the second step is to determine how many cups would be needed for 40 pancakes
5/32 x 40 = 25/4 = 6 1/4
The next step is to convert quart to cups
1 quart = 4 cups
So Maria has 4 cups of milk.
the cups she needs more = 6 1/4 - 4 = 2 1/4 cups

The average like for each minute of the video that he uploads will be 2,000 likes.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The total number of likes is calculated as,
Like / View = 1 / 5
Like / 9,000,000 = 1 / 5
Like = 1,800,000
The total number of minutes is calculated as,
Time length = (9,000,000 / 150,000) x 15
Time length = 60 x 15

Directions: Find the sum for each of the following arithmetic series below. Use the summation
formula to find the sums.
1. A series with six terms, the first term is five, and the common difference is five.
2. A series with six terms, the first term is nine and the common difference is twelve.
3. A series with five terms, the first term is 5.7 and the common difference is 1.4.
Therefore , the solution to the given problem of arithmetic mean comes out to be 1. 105, 2. 234 and 3. 42.5
Arithmetic mean: What is it ?The combination of the amount of all of the values in a list and the number of items in the that list, split by both, is the arithmetic average or mean of the group. The mathematical progression is same to this. This mean of the digits 5, 7, and 9 is 4,
For example, as expression 5 + 7 + 9 is 21, and 21 divided by 3 [there are actually three numbers] equals 7.
Given:
1) There are six terms in AP, with terms a and d each being worth five points.
2) There are 6 terms in AP, with terms 9 and 12 respectively.
3) In AP, there are five terms, where an is 5.7 and d is 1.4.
4) In AP, = 20, t21 = 400
5) In AP, t100 = 99 and a = 0
Find the sum of the terms in the arithmetic series.
As is common knowledge, Sn in the AP equals n/2[2a+(n-1)d]
To determine: the total terms in the arithmetic series
The AP sum of n words is well known. Sn = (n-1)/2[2a+(n-1)d]
1) There are 6 terms in the case where a = 5 and d = 5, as shown by S6 = [2(5)+(61)5] = 3[10+5(5)] = 3[10 + 25] = 3(35) = 105
2) There are 6 terms in the case where a = 9 and d = 12, where S6 = [2(9)+(61)12] = 3[18+5(12)] = 3[18+60] = 3(78) = 234
3) There are 5 terms total, with terms a = 5.7 and d = 1.4.
S5= [2(5.7)+(5—1)1.4] = 2.5[11.4+4(1.4)] = 2.5[11.4+5.6] = 2.5(17) = 42.5

A researcher claims that 45% of U.S. adults think that the IRS is not aggressive enough in pursuing people who cheat on their taxes. You believe the true percentage is more than 45%. To test this, you take a simple random sample of 500 U.S. adults and find that 245 of them say the IRS is not aggressive enough.
Required:
a. What's the minimum population size required?
c. How many successes were there?
c. Test at 0.01 significance.
I’m just tryna get up my bag yurt
Answer:
a) Then minimum sample size is n = 12
b) We got 245 successes
c)p-value is greater than 0,01 Therefore we accept H₀.
We can´t support our claim
Step-by-step explanation:
a) The minimum population size required to use the approximation of binomial distribution to normal distribution can be obtained from:
n*p > 5 p = 0,45 0,45 * n > 5 n > 11
Then minimum sample size is n = 12
b) We got 245 successes out of n = 500
x = 245 p = 245/500 p = 0,49
q = 1 - p q = 1 - 0,49 q = 0,51
Test Hypothesis:
Null Hypothesis H₀ p = 0,45
Alternative Hypothesis Hₐ p > 0,45
Alternative Hypothesis indicates that the test is a one tail test to the right
z( s) = ( p - 0,45 ) / √ p*q/n
z( s) = ( 0,49 - 0,45 ) / √ 0,49*0,51 / 500
z( s) = 0,04 / 0,0223
z(s) = 1,793
p- value for z = 1.79 is from z-table p-value = 0,0367
Comparing p-value with the significance level 0,01 we see that
p-value is greater than 0,01 Therefore we accept H₀.
We can´t support our claim

What is the value of k and why
Answer:
b is the answer
Step-by-step explanation:
The value of k in the equation sin (k - x) = cos (x) would be k = π/2
Given that,
An expression is defined as,
sin (k - x) = cos (x)
Used the concept of trigonometry formula which stated that,
sin (90 - θ) = cos (θ)
Here, the expression is given as,
[tex]sin (k - x) = cos (x)[/tex]
Substitute k = π/2 in the above equation,
[tex]sin (\dfrac{\pi }{2} - x) = cos (x)[/tex]
Apply the above formula,
[tex]\text {cos x } = \text {cos x }[/tex]
So, the value of k is π/2.
Hence, option c is true.

Answer:
x is approximately 48.2.
Step-by-step explanation:
Use the trig function of cosine, or adjacent over hypotenuse.
cos theta = adjacent / hypotenuse
Substitute variables.
cos x = 10 / 15
Apply inverse cosine to both sides.
x = cos^-1(10/15)
Evaluate.
x ≈ 48.2
Answer:
x ≈ 48.2°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{10}{15}[/tex] , then
x = [tex]cos^{-1}[/tex] ([tex]\frac{10}{15}[/tex] ) ≈ 48.2° ( to the nearest tenth )

Therefore ,the top limit of the normal class of three parts of mean class 10th is therefore 60, and the median class is 40–60.
Define mean.Simply average a collection of three or more numbers yields the phrase "mean." The median method, which employs the maximum of a group of products, and the arithmetic average approach, which uses the sum of both the series' values, are two ways to determine the mean for just a given set of numbers.
Given:
Grades received:
X f fi xi
0-20, 10 15 150
20-40, 30 18 540

60-80, 70 29 2030
80-100 90 p 90p
Total: 3770 + 90p + 83p
Mean (3770 plus 90 pi)/(83 plus pi) = 53
=> 3770 + 90p = 83 * 53 + 53p
=> 37p = 629
=> p = 17
17 students received scores in the 80–100 range.
f = 29 and modal class 60-80
minimum of modal class 60
=> 60 + 20 * 8/20
=>68
68 is the modal marks value.
=> ∑fixi = 3770 + 90p = 3770 + 90(17) = 5300
=> 100/2 = 50
60 is the maximum median class for 3 phases of class 10 with a median class of 40–60.
