What is the image of (-9,0) after a reflection over the x-axis?
Answer:
(-9, 0)
Step-by-step explanation:
When a point is reflected over the x-axis, the x-coordinate stays the same but the y-coordinate turns into its opposite. So, the x-coordinate would stay as -9. Because zero is neither negative nor positive, it doesn't have an opposite. So, the y-coordinate would still be 0.

Need to do this Help please
Answer:
Step-by-step explanation:
Now e have two figures
1 is ABCD and other is APQD ,
Now to find g and f,
Now the are both figure is ,
Area = length * width
Area ABCD = 39 cm^2
AB* BC = 39
(g+7) * ( f) = 39Again,
Area APQD = AP*QD= 16 cm ^2
(g)*(f)=16from here f =16/g putt it in above equation we get ,
(g+7)*16/g = 39
16*g-39*g+96 =0
-23g +96 = 0
g = 96/23
g =3 cm
Now for f putt in one of the above equation ,
f =16/3
f =5.33 cm
Answer:
f = 3cm g = 6cm
Step-by-step explanation: to find f
Subtract the area of APQD from ABCD then divide by 7
f = (39 - 18)/7
f = 21/7
f = 3
To find g, divide the area of APQD by 3
18/3 = 6
We can do this because of the givens: ABCD is a rectangle, PQ is parallel to AD, so BC=AD=PQ
When playing the roulette at a casino, you have exactly 1/35 chance of winning in each round if you play a single number. Your friend has rigged up some fireworks to be set off when you win. When you win, he sets off the fireworks every time. When you don't win, he accidentally sets off the fireworks 10% of the time. If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?
Answer:
0.2275 = 22.75% probability that you actually won that round
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Fireworks going off
Event B: You won
Probability of fireworks going off.
100% of 1/35 = 0.0286(when you win)
10% of 34/35 = 0.9714(you lost). So
[tex]P(A) = 0.0286 + 0.1*0.9714 = 0.12574[/tex]
Probability of you winning and fireworks going off:
100% of 1/35, so [tex]P(A \cap B) = 0.0286[/tex]
If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0286}{0.12574} = 0.2275[/tex]
0.2275 = 22.75% probability that you actually won that round
The volume of a cylinder is 225π cm³ and its height is 9 cm.
What is the length of the cylinder's radius?
Enter your answer in the box.
cm
Answer:
5cm
Step-by-step explanation:
Given data
volume = 225π cm³
Height= 9cm
r= ???
Volume of cylinder
v=πr^2h
substitute
225π= π*r^2*9
225= r^2*9
r^2= 225/9
r^2= 25
r= √25
r= 5cm
Hence the radius is 5cm
The present age of Andy and Mike are in the ratio 5:3. If Andy had been 7 years older and Mike 7 years younger, the age of Andy would have been 3 times the age of Mike. Find their present age
Answer: Andy is 35 and Mike is 21.
Step-by-step explanation:
Andy’s present age: Mike’s present age
= 5:3
Andy’s age in “if”: Mike’s age in “if”
=6:2
1 unit = 7
5 unit = 35 (Andy’s age)
3 unit = 21 (Mike’s age)

You are given an isosceles trapezoid ABCD with median XY. Complete the following.
AX = 8, CD = __________
I'll mark brainliest
Answer:
CD=16
Step-by-step explanation:
If XY is median then CD equals 16
Length of CD = 16 .
What is Isosceles trapezoid?An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure.
Given,
Isosceles trapezoid ABCD with median XY.
Median cuts the non-parallel lines of trapezoid in two equal parts.
then,
AX = 8
AB = 2 × AX
AB = 2 × 8
AB = 16
ABCD is isosceles trapezoid
So, Unparallel lines are equal,
AB = CD
⇒ CD = 16 unit.
Hence, 16 unit is length of CD.

They listed the members of the airline's frequent flyer club in alphabetical order and took every tenth member until they succeeded in contacting 170 members. What kind of sampling method have theyused?
a. MULTISTAGE SAMPLING
b. CLUSTER SAMPLING
c. STRATIFIED RANDOM SAMPLING

Answer:
d. SYSTEMATIC SAMPLING
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Took every 10th member, that is, every kth member, which is systematic.

What is the total surface area of the square pyramid in square inches?
Height is 11 in. Base is 7 in. Side Length is 11.5
PLEASE DO THIS QUICKLY
Answer:
Step-by-step explanation:
I assume that "side length" means the slant height of one of the triangular faces.
area of a triangular face = ½(base)(side length) = ½(7)(11.5) = 40.25 in
lateral area = all four triangles = 161 in²
base area = 7² = 49 in²
total surface area = lateral area + base area = 161+49 = 210 in²
The area of the pyramid is 1.4625 ft²
What is a Square Pyramid?If the base of the pyramid is in the shape of a square (base with 4 sides), then it is called a square pyramid. As the square has 4 sides, then the square pyramid has the following properties: No. of Faces: (4+1) = 5 No.of Vertices: (4+1)= 5 No. of Edges: 2(4) = 8
Given here: The height is 11, the base is 7 in, and the side length is 11.5 inches of a pyramid.
The surface area of a square pyramid is the sum of the areas of its square base and four triangular faces:
SA = BA + (4 × FA)
=[tex]a^2+a\sqrt{a^2+4h^2}[/tex]
Where a= base length and height = h
Thus inputting the values we get
SA= 7²+7[tex]\sqrt{7^2+4.11^2}[/tex]
=49+7√533
=210.60 in²
Thus in ft.² we have 1.4625 ft²

1 car = $6 ; 3 car = $18 ; 5car = $30
Step-by-step explanation:
$ 42 = 7 cars
so 1 car = $42÷7 = $6
so 3 cars = 3 × $6 = $18
so 5 cars = 5 × $6 = $30

Answer:
x = 20
Step-by-step explanation:
The picture shows that there is a right angle (this is indicated by the square in between the two straight lines)
every right angle has a total measure of 90 degrees
knowing this we can say: x + 70 = 90 or x = 90 - 70
either way, you would solve this to get x = 20
A set of test scores is normally distributed with a mean of 130 and a standard deviation of 30 What score is necessary to reach the 75th percentile? Select the closest answer
Answer:
A score of 150.25 is necessary to reach the 75th percentile.
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
A set of test scores is normally distributed with a mean of 130 and a standard deviation of 30.
This means that [tex]\mu = 130, \sigma = 30[/tex]
What score is necessary to reach the 75th percentile?
This is X when Z has a pvalue of 0.75, so X when Z = 0.675.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.675 = \frac{X - 130}{30}[/tex]
[tex]X - 130 = 0.675*30[/tex]
[tex]X = 150.25[/tex]
A score of 150.25 is necessary to reach the 75th percentile.
