An online retailer offers next-day shipping for an extra fee. The retailer says that 95% of customers who pay for
next-day shipping actually receive the item the next day, and those who don't are issued a refund. Suppose we
take an SRS of 20 next day orders, and let X represent the number of these orders that arrive the next day.
Assume that the arrival statuses of orders are independent,
Which of the following would find P(X = 19)?

The base of an isosceles triangle is seven less than twice one of the congruent sides. If the perimeter of the triangle is 63 cm, find the length of each side.
Answers
Answer:
17.5
Step-by-step explanation:
let 'x' = each congruent side
let '2x - 7' = side of base
x + 2x - 7 = 63
3x = 70
x = 17.5
-2x - 14 = -2
Solve for x.
Answers
Answer:
X=-6
Step-by-step explanation:
Add 14 on both sides
-2x=12
divide by -2
x=-6
-2x-14=-2
Add 14 to both sides
-2x=12
Divide by -2 to get X by itself
X= -6

a || b . Find the value of the star.
Record your answer as a decimal. Round to the nearest hundredth if necessary.
Answers
Answer:
The star equals 96
Step-by-step explanation:
The star will be equal to 5x-14 because they are vertically opposite.
The two exterior angles are supplementary. Set up the equation
5x - 14 + 3x + 18 = 180 Combine the terms on the left.
8x + 4 = 180 Subtract 4 from both sides
8x = 180 - 4 Combine
8x = 176 Divide by 8
x = 176 / 8
x = 22
===================
5x - 14
5*22 - 14
96

If a wave has a wavelength of 20 meters and is
traveling at a rate of 60m/s, what is its
frequency?
Answers
Answer:
Frequency of wave = 3 Hertz
Step-by-step explanation:
Given that:
Wavelength of wave = 20 meters
Velocity of wave = 60m/s
We know that:
v = fλ
Here,
v = velocity , f = frequency and λ = wavelength
Putting values in formula
60 = f(20)
20f = 60
Dividing both sides by 20
[tex]\frac{20f}{20}=\frac{60}{20}[/tex]
f = 3 Hertz
Hence,
Frequency of wave = 3 Hertz

An angle measures 58.6° less than the measure of its complementary angle. What is the
measure of each angle?
Answers
Answer:
Your answer is 31.4°.
Step-by-step explanation:
The answer itself just requires very simple thinking. Complementary angles are any two angles that add up to 90 degrees. We are given ANGLE<1, so all we have to do is subtract 90 from 58.6 to find ANGLE<2.
90°-58.6°= 31.4°

Write two multiplication equations that compare the number of blue fish 16 to the number of yellow fish 4
Answers
Answer:
b = 4y
y = 1/4 * b
Step-by-step explanation:
Number of Blue fish = 16
Number of yellow fish = 4
Let:
Blue fish = b
Yellow fish = y
b = 4y
b = 4(4)
b = 16
From ;
b =4y
y = b/4
y = 1/4 * b
Hence,
y = 1/4 * 16
y = 16/4
y = 4
2. Write the slope-intercept form of the equation of the line described.
Parallel to y=-x-5; through (4, -3)
Answers
Answer:
y = -x + 1
Step-by-step explanation:
We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.
When two lines are parallel, they have the same slope, so the slope is going to be -1.
New equation: y = -x + b.
Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.
-3 = -4 + b
add 4 to both sides
1 = b
This means that the equation is y = -x + 1
