Answer:
238 chairs are empty
Step-by-step explanation:
Firstly,
you'll have to times 17 by 28 to get the total chairs in the school gym
17 × 28
= 476
Next,
divide it by 2 because half of the gym???
476/2
= 238
So, the amount of the empty chairs in the school gym are 238 in total ｡◕‿◕｡

At Sally's market the ratio of apples to oranges is 4 to 7. If there are 28 oranges at her market
then how many apples are there?
Answer:
16 apples
Step-by-step explanation:
If the original ratio is 4:7.
Then we multiply both numbers by 4. Since 7 x 4 is 28.
So now you have (4x4):(7x4)
Your final ratio is 16 apples : 28 oranges

Answer:
24
Step-by-step explanation:
Use Pythagorean theorem,
base² + altitude² = hypotenuse²
7² + altitude² = 25²
altitude² = 25² - 7²
= 625 - 49
= 576
altitude = √576
altitude = 24

The equation y=2x+3 represents the cost y (in dollars) of mailing a package that weighs x pounds. a. Graph the equation. b. Using the graph, which is the best estimate for the cost to mail the package?
a. Graph the equation.
b. Using the graph, which is the best estimate for the cost to mail the package?
the packedge is 1.126 lb
c. Use the equation to find how much it costs to mail the package.
Answer:
B. Slightly more than $5
Step-by-step explanation:
y = 2x + 3
Firstly we check variables to make sure we understand.
y = dollars
x = pounds
On the scale, it says 1.126 lb. Which means 1.126 pounds.
And so, x = 1.126
y = 2x + 3
y = 2(1.126) + 3
y = 2.252 + 3
y = 2.252
The graph for part a and park b. It is underneath. I wrote 1.1, because it is rounded down from 1.126 lb, which is part b. The one with one line and no dots is part a.

x is another leg next to 6.
10 is the hypotenuse.
a^2 + b^2 = c^2
a & b are legs and c is the hypotenuse.
x^2 + 6^2 = 10^2
x^2 + 36 = 100
x^2 = 100 - 36
x^2 = 64
√x^2 = √64
x = 8

Write an equation of the parabola in vertex form. (-2, 6) (-1, 3)
An equation of the parabola is y=
The equation of the parabola is y = -3(x + 2)^2 + 6
How to determine the parabola equation?From the graph, we have:
Vertex, (h,k) = (-2,6)Point (x,y) = (-1,3)A parabola is represented as:
y = a(x - h)^2 + k
Substitute (h,k) = (-2,6)
y = a(x + 2)^2 + 6
Substitute (x,y) = (-1,3)
3 = a(-1 + 2)^2 + 6
Evaluate
3 = a + 6
Subtract 6 from both sides
a = -3
Substitute a = -3 in y = a(x + 2)^2 + 6
y = -3(x + 2)^2 + 6
Hence, the equation of the parabola is y = -3(x + 2)^2 + 6

Answer:
[tex] \dfrac{4r^6}{st^8} [/tex]
Step-by-step explanation:
[tex] (4r^{-2}st^4)(r^{-4}st^6)^{-2} = [/tex]
Use laws of exponents to simplify the right set of parentheses.
[tex]= (4r^{-2}st^4)(r^{8}s^{-2}t^{-12})[/tex]
Now use the law of exponents for a product of powers with the same base.
[tex] = 4r^6s^{-1}t^{-8} [/tex]
Finally, use the definition of a negative exponent.
[tex] = \dfrac{4r^6}{st^8} [/tex]
Can someone explain how the following Matrix can be multiplied? I thought the column of the first matrix had to match the row of the second and the row of the first had to match the column of the second. I how the matrices listed below as (1x3) and (3x3) respectively. Yet my online Pre-cal course says it's possible. Please explain why this is so.
You are correct in thinking that the columns of the first matrix must match with the rows of the second matrix.
So for example, we can multiply a 1 x 5 matrix with a 5 x 7 matrix. The two matching '5's are directly what make multiplication possible in this case. For your problem, the first two '3's match and multiplication is possible.
The rows of the first matrix don't need to match with the columns of the second matrix.
In a batch of 8000 clock radios 5% are defective. A sample of 13 clock radios is randomly selected without replacement from the 8,000 and tested. The entire batch will be rejected if at least one of those tested is defective. What is the probability that the entire batch will be rejected
Answer:
Step-by-step explanation:
P(A)=1−P(not A)
We can use this here. Event A is that the clock is defective, so Event (not A) means the clock works.
0.02=1−P(not A)
P(not A)=0.98
Therefore, for all the clocks to pass, the probability is P(not A)11.
Now again, we can use complementary counting.
(probability of all clocks failing) = 1 - (probability of all clocks passing)
Probability of all clocks failing = 1−P(not A)11

For this year‘s prom, 35/12 grade students and 28th 11th grade students voted on the theme. The segment take a bar graph below shows the distribution of responses.
Based on the segmented bar graph, does there appear to be an associates between grade level and prom theme?
A yes, there is a different number of students in each class.
B yes, it appears that the 12th grade students prefer the 1920s more than the 11th grade students, and prefer the beach party less.
C no, both distributions of student preferences have the same four categories.
D no, both distributions of student preferences have about the same preference for each of the prom themes.
E no, by the same number of students in each class. Preferred winter wonderland and masquerade ball as prom themes.
Answer:
B
Step-by-step explanation:
Logically and if you observe the graph closely ┐( ∵ )┌
The answer is yes, there appears to be an association between grade level and prom theme based on the segmented bar graph. The Option B is correct
Is there an association between grade level and prom theme?The graph shows that 12th-grade students prefer the 1920s theme more than the 11th-grade students do, and they also have a lower preference for the beach party theme. This indicates a difference in preferences between the two grade levels for these specific prom themes.
This graph provide information on whether both distributions have the same four categories or whether they have the same preference for each of the prom themes, so, its indicate whether the number of students in each class is the same or not.
