Mr. Brown purchased tires for his car. The tires were $75 each, including tax, plus $10 for installation. Mr. Brown paid $160 for the tires and installation. Which equation can be used to find the number of tires, t, that Mr. Brown purchased?

A. t = 160 + 75(10)

B. 75 + t(10) = 160

C. 75t + 10 =160

D. 160t - 75 = 10

She was at 40 feet below, she swam up getting so she was then at 40-10 = 30 feet below sea level.

She the swan 4 feet down so she ended up at 30 + 4 = 34 feet below sea level.

The answer is 34 feet below sea level (-34)

Expression of the collection of variables and constant. The value of the given expression 2x² - y¹ + 3x⁰ for x = 3 and y = 5 will be 16.

An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that all are constrained and create an equation.

Expression is very useful to determine the end or root value of constraint.

As per the given expression,

2x² - y¹ + 3x⁰

Substitute, x = 3 and y = 5

2(3)² - 5 + 3(1) = 18 - 5 + 3 = 16.

Hence "The value of the given expression 2x² - y¹ + 3x⁰ for x = 3 and y = 5 will be 16".

The area of the two shapes combined is 65 inches.

explanation:

A rectangle's formula is length x width which makes the equation 10 x 5 and the solution 50.

A triangle's formula is area = base x height ÷ 2 which makes the equation 10 x 3 ÷ 2 and the solution 15.

Answer:

5[tex]\pi[/tex]+40

Step-by-step explanation:

perimeter of circle=2[tex]\pi[/tex]r

so 5 is r(radius)

so 10[tex]\pi[/tex], but since it’s semicircle, you have to divide by 2, so

5[tex]\pi[/tex]

perimeter of rectangle=15+10+15 because you don’t count the inside, so that equals 40

so 5[tex]\pi[/tex]+40

Step-by-step explanation:

− 1 − 9 + ( −15) + (− 8) + 3 [B.O.D.M.A.S rule]

= − 1 − 9 −15 − 8 + 3

= 3 - 1 - 9 - 15 - 8 (First and last subtraction)

= 3 - 33

= -30(Ans)

Answer:

-30

Step-by-step explanation:

Well we don't necessarily have to follow pemdas right now, because there is only addition and subtraction, and they are on the same level and they don't matter which order they are used in.

So, with that being said, let's go step by step. I could've done an easier way, but for the sake of this question, I will do it a way that is a bit longer.

So, -1-9= -10.

For the next number, if there is a + and then a () and there is a negative number in the parenthesis, forget about the + and just subtract 15.

-10-15= -25

Same for the next number. -25-8= -33

-33+3= -30

The easier method is just combining the negative numbers and adding/subtracting them and then combining the positive numbers and adding/subtracting them, and then combining both results to get your answer.

Step-by-step explanation:

First find out the slope, pick out 2 points. For ex. (-2,0) & (0,4)

Slope=4-0/0-(-2)

=4/2

=2

Y-intercept is 4.

Slope-Intercept form: y=mx+b

m is slope & b is y-intercept

Answer:

139

Step-by-step explanation:

Cause it is

The smallest sample size that will produce the desired interval is 139.

Option C is the correct answer.

The margin of error is the amount of error or uncertainty in a statistical estimate, usually an estimate of a population parameter based on a sample.

We have,

The formula for calculating the margin of error for a confidence interval is:

Margin of error =  z x (√(p x (1-p))/√(n))

where:

z =  the z-score corresponding to the desired confidence level

p =  the estimated proportion of the population that exhibits the behavior of interest (in this case, using a certain brand of a mobile phone)

n =  sample size

We want the margin of error to be at most 0.07, which means we need to solve for the smallest possible value of n that satisfies this condition.

We also want a 90% confidence interval, which corresponds to a z-score of 1.645.

Therefore,

we have:

0.07 = 1.645 x (√(p*(1-p))/√(n))

Squaring both sides and solving for n, we get:

n = ((1.645)² x p x (1-p)) / (0.07)²

We don't know the value of p, so we need to use the worst-case scenario, which is when p = 0.5 (which gives the largest possible value of n for any given margin of error).

Plugging this into the formula, we get:

n = ((1.645)² x  0.5 x (1-0.5)) / (0.07)²

n = 138.55

Since n must be a whole number, the smallest sample size that will produce the desired interval is 139.

Therefore,

The smallest sample size that will produce the desired interval is 139.
