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

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.

Write an equation of the parabola in vertex form. (-2, 6) (-1, 3)
An equation of the parabola is y=
Answers
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

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?
Answers
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

Step-by-step explanation:
The ratio shows that Kyle gets 3 parts of the money, Meg gets 2 parts of the money, and Dan gets 7 parts of the money. Simple addition lets us know there are 10 parts of the money, and because Meg got 2 of them, she has 2/10ths of the money, or 1/5.

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
Answers
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

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.
Answers
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.
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.
Answers
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.
