B. 1,266 mph
C. 432 mph
D. 423 mph
Answer:
423 mph
Step-by-step explanation:
To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.

HELP Members of a soccer team suspect the coin used for the coin toss at the beginning of their games is unfair. They believe it turns up tails less often than it should if it were fair. The coach of the team decides to flip the coin 100 times and count the number of tails. His trial results in 35 tails. He decides to carry out a significance test. What is the p-value he obtains and the general conclusion that can be made at a 99% significance level?
The p-value is 0.0013. He should reject the null in favor of the alternative.
The p-value is 0.0013. He should fail to reject the null.
The p-value is 0.9987. He should reject the null in favor of the alternative.
The p-value is 0.9987. He should fail to reject the null.
There is not enough information provided to calculate the p-value and make a conclusion.

Express in the form 1: n.
Give n as a decimal.
8 : 6
please help
Answer:
n = 0.75
1 : 0.75
Step-by-step explanation:
To get from 8 to 1, you have to divide by 8. You do that to the number 6.
6/8 = 3/4 = 75/100.
Therefore, n = 0.75.
A suitcase measures 21 inches by 16 inches. What is the length of the diagonal of the suitcase to the nearest tenth of an inch?
Answer:
Step-by-step explanation:
we have a rectangle that measure 21 inches by 16 inches
to find the rectangle(which is the hypotenuse) we will use Pythagorean theorem
c^=a^2+b^2
c^=21^2+16^2=697
c=[tex]\sqrt697}[/tex] =26.40 which rounded to the nearest tenth =26

Please help!!!!!
Answer:
12
Step-by-step explanation:
if you draw the picture in your copybook you will see that there is a right triangle, we have the Pythagorean theorem i.e c=√a²+b²
15=√9²+x². the trees tall=X
15²=9²+x²
x²= 144
X= 12

Answer:
x = -4 , x = -1
Step-by-step explanation:
x² + 5x + 4 = 0
1) write 5x as a sumx² + 4x + x + 4 = 0
2) factor out x from the expressionx ( x + 4 ) + x + 4 = 0
3) factor out x + 4 from the expression( x + 4 )( x + 1 ) = 0
4) the product of factors equals to 0i) x + 4 = 0
x = -4
ii) x + 1 = 0
x = -1

solving systems of linear inequalities
Answer:
YES. (2, 7) is a solution of the system.
Step-by-step explanation:
System of linear inequalities has been given as,
y ≥ -x + 1 --------(1)
y < 4x + 2 ------(2)
If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.
By substituting the coordinates of point (2, 7) in inequality (1),
7 ≥ -2 + 1
7 ≥ -1
True.
By substituting the coordinates of point (2, 7) in inequality (2),
7 < 4(2) + 1
7 < 9
True.
Therefore, point (2, 7) lie in the solution area of system of inequalities.
YES. (2, 7) is a solution of the system.

A teacher has 396 pieces of candy. If there are 44 students, 6 of whom are boys, if divided evenly, how many pieces of candy will each student get?
Answer:
9 pieces of candy.
Step-by-step explanation:
The information about how many boys there are is irrelevant, so we can just ignore that.
The important information is that the teacher has 396 pieces of candy and that it is split between 44 students equally.
So, to solve, we just do 396 / 44 = 9.
Therefore, each student will get 9 pieces of candy.

Stephanie ran three sprints during practice. Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards. What was the total distance that Stephanie sprinted?
Answer:
Stephanie sprinted 550 yards.
Step-by-step explanation:
Given that,
Stephanie ran three sprints during practice.
Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards.
We need to find the total distance that Stephanie sprinted. It is simply equal to the sum of all above sprints.
Distance = 175 yards + 150 yards + 225 yards
= 550 yards
Hence, Stephanie sprinted 550 yards.

1/2=2m then what is m?
Answer:
m = 1/4 or 0.25
Step-by-step explanation:
1/2 = 2m
[Symmetric property of equality]
2m = 1/2
÷2. ÷2
[Division property of equality]
m = 1/2 ÷ 2
m = 1/4
________
1/2 = 2m → 1/2 = 2(1/4) → 1/2 = 2/4 →
1/2 = 2÷2/4÷2 → 1/2 = 1/2

Find the slope of the line through (9, 4) and (0, 5).
Answer:
It's just y2-y1 over x2-x1
Step-by-step explanation:
so pick a coordinate and make it 1 and make the other one 2 and put in the numbers.
The slope of the line will be m = -1/9.
What is the general equation of a Straight line?The general equation of a straight line is -y = mx + c
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis
Other possible equations of line are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a line through (9, 4) and (0, 5).
The slope of the line will be -
[m] = (4 - 5)/(9 - 0)
[m] = - 1/9
Therefore, the slope of the line will be m = -1/9.

A rectangle has a perimeter of 30cm the width of the rectangle is n cm the length of the rectangle is n+6cm
What’s the value of n
Step-by-step explanation:
p=2(l+w)
30cm=2(n+6+n)
30cm\2=2n+6
15cm-6=2n
9cm=2n
n=4.5cm or w=4.5cm
l=w+6
l=4.5cm+6
l=10.5cm
