The toll for driving the segment of a certain freeway is $1.50 plus 25 cents for each mile
traveled. Joy paid a $ 25.00 toll for driving a segment of the freeway. How many miles did she
travel?
Answer:
Step-by-step explanation:
t=1.5+0.25m, if t=25 then
1.5+0.25m=25
0.25m=23.5
m=94
So she drove 94 miles.

Step-by-step explanation:
[tex]9x + 4 = 5x - 6[/tex]
Collect like terms and simplify
[tex]9x - 5x = - 6 - 4 \\ 4x = - 10[/tex]
Divide both sides of the equation by 4

Step-by-step explanation:
m<2=49° (vertically opposite angles are equal)
m3=112° (vertically opposite angles are equal)
m1= 112°+ m1 =180 (the sum of interior angles measure 180°)
hence, m1 = 180 - 112°
m1= 68°

At airports, some people are randomly selected for extra security screening. It is claimed that 25% of all passengers are screened. A recent flight contained 5 passengers in first class, none of whom were chosen for additional screening.
We want to perform a simulation to estimate the probability that 0 out of 5 passengers would be chosen in a random selection process.
Let 0 = chosen for extra screening, and 1, 2, and 3 = not chosen for extra screening. Skip the digits 4 through 9. Using the digits shown below, how many passengers, out of 5, are selected for extra screening?

Camille buys a cake for $\$24.99$ . She also buys $12$ brownies. Each brownie costs the same amount. She spends $\$39.99$ on the cake and the brownies. Camille finds the cost of each brownie by calculating $(39.99\ -\ 24.99)\ \div\ 12$ . Tanya finds the cost of each brownie by solving the equation $39.99\ +\ 12b\ =\ 24.99$ , where $b$ is the cost of each brownie. Which approach uses the sequence of operations necessary to find the cost of each brownie: Camille’s, Tanya’s, both, or neither? Explain why. Respond in the space provided.
The cost of each brownie is $1.25
Equation and expressionsLet the cost of each brownies be x
If she buys 12 brownies and each brownie costs the same amount, the cost of 12 brownies will be 12x
To find the value of x;
39.99 = 24.99 + 12x
12x = 15
x = 15/12
x = $1.25
Hence the cost of each brownie is $1.25

Answer:
sin2θ = [tex]\frac{1320}{3721}[/tex]
Step-by-step explanation:
Given
sinθ = [tex]\frac{11}{61}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
This is a right triangle with legs 11 and x ( adjacent ) and hypotenuse 61
Using Pythagoras' identity in the right triangle to find x
x² + 11² = 61²
x² + 121 = 3721 ( subtract 121 from both sides )
x² = 3600 ( take the square root of both sides )
x = [tex]\sqrt{3600}[/tex] = 60
Then cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{60}{61}[/tex]
Using the identity
sin2θ = 2sinθcosθ , then
sin2θ = 2 × [tex]\frac{11}{61}[/tex] × [tex]\frac{60}{61}[/tex] = [tex]\frac{1320}{3721}[/tex]
write the equation of a line perpendicular to y= -1/3x + 5 and passes through the point (6, 4).
Answer:
y = 3x - 14
Step-by-step explanation:
Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.
Plug in the slope and given point into y = mx + b, then solve for b:
y = mx + b
4 = 3(6) + b
4 = 18 + b
-14 = b
Plug in the slope and y intercept into y = mx + b
y = 3x - 14
So, the equation of the line is y = 3x - 14

Mary runs around a circular track with a radius
of 25 meters. If she runs at 75 meters per minute,
how many minutes will it take her to run one lap
around the track, rounded to the nearest integer?
Answer:It will take Mary about 2 minutes to run one lap.
Step-by-step explanation:
c = 2[tex]\pi[/tex]r = 2 * 3.14 * 25
2 * 3.14 = 6.28
6.28 * 25 = 157
157/ 75 = 2 w/ remainder of 7
Round down and it is roughly 2 minutes.

After checking that conditions are met, you perform a significance test of 0:=1 versus :≠1 . You obtain a -value of 0.022.
Which of the following must be true?
A 95% confidence interval for will include the value 0.022.
A 99% confidence interval for will include the value 1.
None of these is necessarily true.
A 99% confidence interval for will include the value 0.022.
A 95% confidence interval for will include the value 1.
Answer:
A
Step-by-step explanation:
The true statement is
A 99% confidence interval for will include the value 1.
What is Confidence Interval?The range of values that we observe in our sample and for which we anticipate finding the value that accurately reflects the population is referred to as a confidence interval.
Given:
[tex]H_0: \mu = 1\\H_\alpha : \mu \neq 1[/tex]
P= 0.022
If the P- value is smaller than significance level, then the null hypothesis is rejected.
P< 0.05 - 5% Reject [tex]H_0[/tex]
P> 0.01 = 1% Fail to Reject [tex]H_0[/tex]
A 95% Confidence interval correspond with a significance test at the 5%
significance level.
A 99% Confidence interval correspond with a significance test at the 1%
significance level.
If the Significance test was Significant then the interval does not contain the value mentioned in the Hypothesis.
95% CI does not contains 1.
99% CI contains 1.
