Answer: Its remainder is 1 when you divide 17 by 2.
In other words, 17/2 = 8 remainder 1.
The 8 is the quotient.
The reason why we know we get a remainder 1 is because the condition of "if n is an odd number" and here n = 17 is odd. So the first condition is met allowing us to use the full "if, then" statement given to us.

1.Jose is solving an equation 4(x-2) = 18. The first step to solving is 4x -8 = 18. What would the
next step be?
PLS HELP THANK YOU
Answer: x = 13/2
Step-by-step explanation:
Distribute: 4(x - 2) = 18
4x - 8 = 18
Add 8 to both sides
4x - 8 + 8 = 18 + 8
Simplify:
4x = 26
Divide both sides of the equation by the same term
4x = 26
4x/4 and 26/4
Cancel term that are both in the numerator and denominator
Divide the numbers
X = 13/2
Simplify the following expression.
(4x2 + 8x + 15) + (x2 - x - 27) - (x + 5)(x - 7)
What’s the answer?
Answer:
4x^2+19x-47
Step-by-step explanation:
(4x^2+8x+15)+(x^2-x-27)-(x-5)(x-7)
=(4x^2+8x+15)+(x^2-x-27)-x^2+7x+5x-35
=(4x^2+x^2-x^2) + (8x-x+7x+5x) + (15-27-35)
= 4x^2+19x-47
Hope this helps!

Suppose you have a 6-face unfair dice with numbers 1,2,3,4,5,6 on each of its faces. If the probability distribution of throwing a number up is as follows: 1 with probability 1/12 2 with probability 1/12 3 with probability 1/12 4 with probability 1/12 5 with probability 1/12 6 with probability 7/12 What are the mathematical expectation and variance of the dice based on the above probability distribution
Answer:
Expectation is equal to 4.75
Variance is equal to 3.02
Step-by-step explanation:
Consider the attached image.
Let [tex]x_i[/tex] denotes each of the outcome.
Expectation [tex]=E(X)[/tex] = ∑[tex]x_if(x_i)[/tex]
[tex]=1(\frac{1}{12}) +2(\frac{1}{12}) +3(\frac{1}{12}) +4(\frac{1}{12}) +5(\frac{1}{12}) +6(\frac{7}{12})[/tex]
[tex]=\frac{1}{12}+\frac{2}{12}+\frac{3}{12}+\frac{4}{12}+\frac{5}{12}+\frac{42}{12}\\\\=\frac{57}{12}\\\\=4.75[/tex]
[tex]E(X^2)=[/tex] ∑ [tex]x_i^2f(x_i)[/tex]
[tex]=1^2(\frac{1}{12}) +2^2(\frac{1}{12}) +3^2(\frac{1}{12}) +4^2(\frac{1}{12}) +5^2(\frac{1}{12}) +6^2(\frac{7}{12})[/tex]

Variance [tex]=E(X^2)-[E(X)]^2[/tex]
[tex]=(\frac{307}{12})-(\frac{57}{12})^2\\\\ =\frac{307}{12}-\frac{3249}{144}\\\\ =\frac{3684-3249}{144}\\\\ =\frac{435}{144}\\\\ =3.02[/tex]

An angle is 1/3 the measure of its complement. What is the measure of the angle, the complement and the supplement?
Answer:
Angle: 22.5 deg, Complement: 67.5 deg, Supplement: 157.5 deg
Step-by-step explanation:
22.5 is 1/3 of 67.5
so compliment is 67.5.
Supplement is just adding another angle so I chose 7.
I did 22.5 x 7 = 157.5
Another example would be:
Angle: 10 deg, Complement: 30 (because 10 x 3), Supplement: 70 (because 10 x 7)

Taking an Uber ride in NYC has an initial fee of $2.55 with an additional charge of $1.75 per mile (we will ignore the small per minute waiting fee). In equation form, cost = 2.55 + 1.75(miles). a local NYC resident records the number of miles for his first 25 rides with Uber. The mean distance of his rides is 5.6 miles with a standard deviation of 1.2 miles. a) Find the mean cost of the 25 trips.
b) Calculate the standard deviation of the cost of the 25 trips.
Answer:
a) The mean cost of the 25 trips is:
$12.35.
b) The standard deviation of the cost of the 25 trips is:
$52.50
Step-by-step explanation:
a) Data and Calculations:
Initial fee (fixed) = $2.55
Variable (additional) charge = $1.75 per mile
Equation = 2.55 + 1.75(miles)
Trips = 25
Mean distance for first 25 rides = 5.6 miles
Standard deviation = 1.2 miles
Mean cost of the 25 trips = 2.55 + 1.75 (5.6) = $12.35
Total cost = $308.75 (25 * 12.35) based on mean cost
Standard deviation of the cost of the 25 trips:
Total standard deviation for the 25 trips = 30 miles (1.2 * 25)
= $52.50 (1.2 * 25 * $1.75)

The measure of angle B in a triangle is 4 more than twice the measure of angle A. The measure of angle C is 30 less than 3 times the measure of angle A. Find the measure of each angle.
Answer:
[tex]A = 34\frac{1}{3}[/tex]
[tex]B = 72\frac{2}{3}[/tex]
[tex]C = 73[/tex]
Step-by-step explanation:
Given
Shape: Triangle
[tex]B = 4 + 2A[/tex]
[tex]C = 3A - 30[/tex]
Required
Solve for A, B and C
Since the shape is a triangle,
[tex]A + B +C = 180[/tex]
Substitute [tex]B = 4 + 2A[/tex] and [tex]C = 3A - 30[/tex] in [tex]A + B +C = 180[/tex]
[tex]A + 4 + 2A + 3A - 30 = 180[/tex]
Collect Like Terms
[tex]A + 2A + 3A = 180 + 30 - 4[/tex]
[tex]6A = 206[/tex]
Solve for A
[tex]A = 206/6[/tex]
[tex]A = 34\frac{1}{3}[/tex]
Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]B = 4 + 2A[/tex]
[tex]B = 4 + 2 * 34\frac{1}{3}[/tex]
[tex]B = 4 + 2 * \frac{103}{3}[/tex]
[tex]B = 4 + \frac{206}{3}[/tex]
[tex]B = \frac{12 + 206}{3}[/tex]
[tex]B = \frac{218}{3}[/tex]
[tex]B = 72\frac{2}{3}[/tex]
Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]C = 3A - 30[/tex]
[tex]C = 3 * 34\frac{1}{3} - 30[/tex]
[tex]C = 3 * \frac{103}{3} - 30[/tex]
[tex]C = 103 - 30[/tex]
[tex]C = 73[/tex]

An item is regularly priced at $85. Salma bought it on sale for 35% off the regular price.
Answer:
55.25
Step-by-step explanation:
85 X 0.35 = 29.75
85 - 29.75 = 55.25
Answer: 29.75
My Explanation:
85 divided by 10 = 8.5 (10%)
8.5 x 4 = 34.0 (40%)
8.5 divided by 2 = 4.25 (5%)
34 - 4.25 = 29.75 (35!)

Step-by-step explanation:
I'm not sure exactly what you are asking for but here is what the box plot tells you:
Minimum is 17 items.
Q1 (Lower Quartile) is 22 items. So, 25% of the customers bought 22 items.
Q2 (Median) is 32 items. So, 50% of the customers bought 32 items.
Q3 (Upper Quartile) is 35 items, So, 75% of the customers bought 35 items.
Maximum is 62 items.
The data is "heavier" on the right so it is skewed left.
Range is 62 - 17 = 45
IQR (Interquartile range) is Q3 - Q1 = 35 - 22 = 13
how do u solve this its pre-algebra 4x – 5y = 20
Answer:
x = 5 + 5y/4
Step-by-step explanation:
I think its like this: 4x - 5y = 20
Add 5y to both sides: 4x = 20 + 5y
Divide both sides by 4: x = 20/4 + 5y/4
Simplify: x = 5 + 5y/4
I'm pretty sure it is like this
