A rental car company charge $37. 93 per day to rent a car and $0. 11 for every mile driven. Taylor want to rent a car, knowing that:
She plan to drive 50 mile. She ha at mot $300 to pend. Which inequality can be ued to determine
d
d, the maximum number of day Taylor can afford to rent for while taying within her budget?
The inequality that can be used to determine the maximum number of days, d, Taylor can afford to rent for while staying within her budget is $37. 93(d) + $0. 11(50) < $300 or d < 7.76.
Inequality is defined as the relationship between non-equal numbers or expressions separated by <, >, ≤, or ≥.
Let d be the maximum number of days Taylor can afford to rent for while staying within her budget.
If a rental car company charges $37. 93 per day to rent a car and $0. 11 for every mile driven, and Taylor plans to drive 50 miles, then it will cost her $37. 93(d) + $0. 11(50).
If she has $300 at most to spend, then the inequality should be d < 7.76
$37. 93(d) + $0. 11(50) < $300
37. 93d + 5.5 < 300
37. 93d < 294.5
d < 7.76

Find the simplified product where x20: √5x (√8x²-2√x)
√10x
2x √40x-2x
O 2x10x-2√5x
O2x10x-2x√√5
DONE
The solution of the expression is 2√5x(√2-1).
From the question, we have
√5x ( √8x² - 2√x)
= √5x ( 2√2x - 2√x)
= √5x(√2-1)(2√x)
= 2√5x(√2-1).
The solution of the expression is 2√5x(√2-1).

The expected value is 11.134
The expected value can be calculated as:
EV = ∑xₙ*pₙ
Where xₙ is the n-th outcome. For the case of the spinner we have 2 possible outcomes:
x₁ = 9
x₂ = 4
And pₙ is the probability of the n-th event.
For the case of each spinner, the probability of each section will be equal to the quotient between the degrees of each arc, and the total number of degrees in a circle (360°).
First, we can see that for outcome = 9, the angle is a right angle, then it is equal to 30°, then the probability of this event will be:
p₁ = 30°/360° = 0.083
And the angle for the second arc must be such that:
30 + A = 360°
A = 360 - 30 = 330
Then the probability for the outcome = 4 is:
p₂ = (330°/360°) = 0.916
Now we can find the expected value as:
EV = (*9 x 0.083 + 4 x 0.916 ) = 11.134
Therefore, the expected value is 11.134

What is the amount of error that you will accept in the upper tail of the confidence interval?.
The amount of error that you will accept in the upper tail of the confidence interval as follows
The amount of error that will accept in the upper tail is = 13.97
Amount of error = margin of error
Margin of error = [tex]Z\frac{\alpha }{2} \frac{s}{\sqrt{n} }[/tex]
93% = confidence interval =1- [tex]\alpha[/tex]
=1-.93
=0.07
Hence [tex]\frac{\alpha }{2}[/tex] =0.035
[tex]Z\frac{\alpha }{2} or t\frac{\alpha }{2} = 1.81[/tex]
This problem represents two tail test because a two-tailed test is a method in which the critical area of a distribution is two-sided and tests whether a sample is greater or less than a range of values.
And confidence interval are always two tailed.
So margin of error = [tex]1.81x\frac{1.99}{\sqrt{40} }[/tex]
= 0.57
Upper tail C.I = x + margin of error
=13.4+0.57
=13.97
Lower tail C.I = x - margin of error
= 13.4 - 0.57
=12.83
Hence the answer is, the amount of error that will accept in the upper tail is = 13.97.

Answer: x = 140°
Step-by-step explanation:
The sum of all interior angles in a pentagon is 540°.
Since you have every other angle except for one, you can subtract them from the total:
540°-120°-118°-89°-73° = 140°
Therefore the x angle is equal to 140°.

There are 15 girls in your class this year. That is a 15% increase from last year. Write a proportion to solve for the number of girls in the class last year.
First, we have to recognize that if the current number of girls in the class is a 15% increase from last year, then this year's number is 115% of last year's number.
With that, we can set up a proportion comparing last year to this year, in both percentages and numbers:
[tex]\dfrac{100}{115} = \dfrac{x}{15}[/tex]
Note that both numerators are last year's values and the denominators are this year's values.
If we multiply both sides by 15, we have that x ≈ 13.043478260869565. Since we're dealing with whole people, we'd say that there were 13 girls in the class last year.
when sample size increases, everything else remaining the same, the width of a confidence interval for a population parameter will:
when sample size increases, everything else remaining the same, the width of a confidence interval decreases.
The sample size is defined as the the number of observations or participants included in a study.
The confidence interval is defined as the mean of the estimate plus and minus the variation in that estimate. That means when you do the test multiple times, then the value may be vary from the estimated value. The confidence interval is the range of those values.
So when the sample size increases the width of the confidence interval decreases
Hence, when sample size increases, everything else remaining the same, the width of a confidence interval decreases.

Step-by-step explanation:
many greetings to your teacher, there are some definitions missing.
this can only be done if JM and LH are true diameters of the circle.
1. if LH is a diameter, then angles KAH + LAK = 180°.
KAH = 90° (right angle).
so,
angle LAK = 180 - 90 = 90°.
2.
with JM and LH being diameters, JAH = LAM = 42°.
JAH + JAK = 90°.
angle JAK = 90 - 42 = 48°.
3. angle LAJ = LAK + JAK = 90 + 48 = 138°.
4. see also 2.
these are angles of intersecting lines (diameters). they must be the same on both sides of such an intersected line (just left-right mirrored).
JAH = LAM = 42°.
5. angle KAM = LAK + LAM = 90 + 42 = 132°.
6. arc angle LK = angle LAK = 90°.
7. arc angle JK = angle JAK = 48°.
8. arc angle LMG = angle LAG = 180 - HAG =
= 180 - 30 = 150°.
9. arc angle JH = angle JAH = 42°.
10. arc angle KLM = angle KAM = 132°.
the united company had 15 applications for funding this year. if 8 of these applications can be funded, how many different lists of successful applications are there
A company received 15 funding applications and want to select 8 of them to be funded. The number of different lists of successful applications is 6,435
Suppose we have n objects in total and we want to select r objects among total objects, the number of ways they can be selected is given by the combination formula:
ⁿCr = n! / [r! (n-r)!]
Data from the problem:
n = total applications = 15
r = number of selected applications = 8
Hence, the number of different lists of successful applications is:
¹⁵C₈ = 15! / [8! (15-8)!]
= 15! / [8! 7!]
= 6,435
Thus, the number of different lists can be selected is 6,435

Every time a force pushes something over a distance, work is done. By multiplying the force by the distance moved in the force's direction, you may determine the energy transferred, or work done. Energy transmitted equals work done, which is force times the distance travelled in the force's direction.

in a test for particular illness, a false-positive result is obtained about 1 in 125 times the test is administered. if the test is administered to 15000 people, obtain the approximate probability of there being more than 135 false-positive results?
The probability of being more than 135 false-positive result is equal to 0.0853.
As given in the question,
Probability of false positive 'p' = 1/125
= 0.008
Number of people tested 'sample size n' = 15,000
Mean 'μ' = np
= 15000 × 0.008
= 120
Standard deviation 'σ' = √n × p × ( 1 - p )
= √15000 × 0.008 × ( 1 - 0.008)
=√ 15000 × 0.008 × 0.992
= √119.04
= 10.9
z = (X - μ) /σ
Approximate probability of being more than 135 false-positive results
= P( X > 135)
= P[( X - μ )/σ > ( 135 - μ)/σ
= P ( z > (135 - 120)/ 10.9)
= P ( z > 1.37)
= 1 - P ( z ≤ 1.37)
= 1 - 0.9147
= 0.0853 ( from z table)
Therefore, probability of being more than 135 false-positive results is equal to 0.0853.
