You pick a card at random, put it back, and then pick another card at random.
6, 7, 8, 9.
What is the probability of picking a 9 and then picking a number greater than 7?
Write your answer as a percentage.
Answers
Answer:
12.5%
Step-by-step explanation:
There are 4 cards to choose from in the beginning.
Pick 9 out of the 4.
p(9) = 1/4
You put the card back. Now there are again 4 cards.
There are 2 numbers greater than 7: 8 and 9.
p(8 or 9) = 2/4 = 1/2
p(9 then number greater than 7) = 1/4 × 1/2 = 1/8
1/8 = x/100
8x = 100
x = 100/8
x = 12.5%
Answer: 12.5%

The histogram shows the number of points scored by a basketball team for one season. A histogram titled points scored in one season shows the number of games in which a certain number of points were scored. The data is as follows. 69 to 76 points: 3 games. 77 to 84 points: 6 games. 85 to 92 points: 8 games. 93 to 100 points: 1 game. According to the histogram, in what percentage of games did the team score between 77 and 92 points? Enter your answer in the box. Round your answer to the nearest percent.
Answers
Find the total number of games with points scored between 77 & 92 pts - 14
To find the percentage divide 14/18 - .777
Multiply .777*100 - 77.7
Round to 78%
Percentage of games the team scored between 77 and 92 is 77.7% .
Given data from the histogram shows the number of games that are played in the range of 77 - 92.
Total number of games played = 18
Number of games played in the range 77 - 92 = 14
Percentage of games played in the range 77-92 = (Number of games played in the range 77 - 92) / (Total number of games played) × 100
Percentage = (14)/(18) × 100
= 77.7% .
Hence the number of games played in the given range is 77.7%.

Answer:
24
they each will need to fill their bottle 24 times (48 times in total)
Step-by-step explanation:
There are 768 ounces in 6 gallons.
If each bottle carries 16 ounces in total to fill up the tank it would take 48 bottles. ( 48*16=768)
There is two students though, so you split it. (48/2=24)
Therefore each student need to fill there bottle 24 times to fill up the tank.

Answer: The y-value of the y-intercept is -5
Step-by-step explanation:
The y-intercept of a line is the point where it intersects the y-axis. In the given linear equation, y = 2x - 5, the y-intercept is the value of y when x is equal to 0.
To find the y-intercept, substitute x = 0 into the equation:
y = 2(0) - 5
y = -5
Therefore, the y-value of the y-intercept is -5.

Least Value - -s
Greatest Value - s
Closer to Zero - s + r
Step-by-step explanation:
r = about -2
s = about 2
-s = exactly -2
r + s = about 0
When looking at the number line, s is the farthest away right from zero, making it the variable with the most value that is at least two.
Since the expression has a choice of a negative s, it would simply mean that two would become negative two.
Since you know the values of s + r, you will know that -2 + 2 would equal to 0.
Overall-The least value would be -s
-The greatest value would be s
-The expression that is closer to zero would be s + r

Determine which integer in the solution set makes this true: 4x -9 = 31 S:{ -10, 5.5, 9, 10}
Answers
Answer: 10
Step-by-step explanation: 4x-9=31
4x=31+9
4x=40
4x/4=40/4
x=10
Answer: 10. 4(10)-9=31
Step-by-step explanation:
firstly, we would substitute the values given in the subset to the value of x and check which solves the equation.
When x= (-10),
4(-10) -9
= -40-9
=-49,
which does not equal 31, so it cannot be -10.
Similarly, when x=5.5,
4(5.5)-9
=22-9
= 13
which does not equal 31.
Thirdly, when x=9
4(9) -9
= 36-9
= 27
which does not equal 31.
Finally,
when x=10,
LHS 4(10)-9
=40-9
=31 RHS
Therefore x=10.

Ms. Tanaka drove 3,001 miles from Massachusetts to California. It took her hours to drive this distance. How many miles did Ms. Tanaka drive per hour?
Answers
Answer:
your question is incomplete . It doesnt contain the number of hours
The number of miles Ms. Tanaka drive is 60 miles per hour.
We are given that;
Number of miles= 3001
If Ms. Tanaka drove 60 miles in an hour, then her rate of driving is:
rate = distance / time
where distance is 60 miles and time is 1 hour. Therefore:
rate = 60 / 1
Simplifying, we get:
rate = 60 miles per hour
Therefore, by the speed answer will be 60 miles per hour.

In What year does the car's value start to increase? Part B. Will the car's will ever begin to decrease? Assume it follows its modeled value.
Answers
The value of a classic car produced in 1972 can be modeled by the given function, the car's value starts to increase after 12 years since 1972, which would be in the year 1972 + 12 = 1984.
To discover the year whilst the car's fee begins to increase, we want to determine the factor at which the spinoff of the function V(t) modifications from poor to advantageous. The spinoff represents the fee of alternate of the function.
V'(t) = 2 * 19.25t - 440
2 * 19.25t - 440 > 0
38.5t - 440 > 0
38.5t > 440
t > 440 / 38.5
t > 11.428
Since t represents the wide variety of years seeing that 1972, we round up to the closest whole variety, which gives us t > 12.
Therefore, the car's value starts to increase after 12 years since 1972, which would be in the year 1972 + 12 = 1984.
Since the equation for the automobile's fee, V(t), is a quadratic characteristic with a fine coefficient for the [tex]t^2[/tex] term (19.25), the parabola opens upwards.
Thus, this manner that the car's fee will in no way begin to lower but will maintain to growth or continue to be constant over the years in step with the modeled price.

A glide reflection is a transformation that is made up of a translation and a reflection across a line the is parallel to the direction of the translation.
A. Graph triangle DEF with vertices D(1,-1) E(7,-3) F(2,-7)

C. Are the two figures congruent?
Answers
Answer:

Step-by-step explanation:k
The vertices of the image triangle after the glide reflection are D'(1, 7), E'(7, 5), F'(2, 1) and both the triangles are not congruent
Graph of triangle DEF with vertices D(1,-1), E(7,-3), F(2,-7):
To graph the triangle, plot the given coordinates on a coordinate plane and connect the points to form a triangle.
D(1,-1), E(7,-3), F(2,-7)
Graph of triangle DEF under a glide reflection where the translation is (x,y) —> (x, y+8):
To perform the glide reflection, we first apply the translation by adding 8 to the y-coordinate of each vertex, and then we reflect the resulting triangle across a line parallel to the direction of the translation.
Translation: (x,y) —> (x, y+8)
Applying the translation to the original triangle DEF:
D(1, -1+8) = D(1, 7)
E(7, -3+8) = E(7, 5)
F(2, -7+8) = F(2, 1)
Now we have the new vertices for the translated triangle:
D(1, 7), E(7, 5), F(2, 1)
Next, we reflect this translated triangle across a line parallel to the direction of the translation. Since the direction of the translation is vertical, the reflection line will also be vertical.
The resulting image triangle after the glide reflection will have the same vertices as the translated triangle, but mirrored vertically.
The vertices of the image triangle after the glide reflection are:
D'(1, 7)
E'(7, 5)
F'(2, 1)
The original triangle DEF and the image triangle after the glide reflection are not congruent.
