If a test has 95 questions how many points would each question be worth? Using your answer how many could you miss without going below an 80?

Answers

Answer 1

Answer:

One can miss up to 24 questions and still achieve an 80% score.

In order to calculate the points each question is worth and determine how many questions you can miss while maintaining an 80% score.

To find the points each question is worth, we divide the total points by the number of questions. Let's assume the test is out of 100 points, which is a common scale. Therefore, each question would be worth $(100)/(95)$ or approximately 1.05 points.

Now, let's determine how many questions you can miss while still achieving an 80% score (which is 80 out of 100 points). We'll set up an equation to solve for the maximum number of questions you can miss, denoted by "x":

$80 = (100 - x)/(95) * 100$

To solve for "x," first, we'll simplify the equation:

$80 = (10000 - 100x)/(95)$

Next, we'll isolate "x" by multiplying both sides by 95:

$7600 = 10000 - 100x$

Now, isolate "-100x" by subtracting 7600 from both sides:

$-2400 = -100x$

Finally, divide both sides by -100 to solve for "x":

$x = (-2400)/(-100) = 24$

So, you can miss up to 24 questions and still achieve an 80% score.

Answer 2

Answer: 100/95= 1.05. Each question worth 1.1 rounded. You could miss 19 but if you miss 20 you go under 80.

Step-by-step explanation:

An airplane traveling at 400 mph at a cruising altitude of 7.2 mi begins its descent. If the angle of descent is 1 degree from the horizontal, determine the new altitude after 15 minutes. Round to the nearest tenth of a mile.

Answers

Answer:

New altitude = 5.5 miles

Step-by-step explanation:

We are given;

Velocity = 400 m/h

Angle of descent = 1°

Altitude = 7.2 miles

Time = 15 minutes = 15/60 hours = 0.25 hours

Now, the downward component of its speed is;

Vy = (400)sin(1°)

Vy = 6.98 mph

After a time t, its height will be;

h(t) = (7.2 - 6.98t) miles, for t = hours

We are given;t = 0.25 hrs

Thus;

h(0.25) = 7.2 - (6.98*0.25) miles

h(0.25) = 5.46 miles

h(0.25) ≈ 5.5 miles to the nearest tenth

sales at Cycle Time increased by 370% this year. Which of the following is equivalent to 370%? 37/100, 3.7, 3 7/100 or 37? How do I figure this out?

Answers

The answer would be 3.7. I got this by first writing 370% as a fraction. Because percents are over 100, I wrote 370/100. From there, I simplified it. First, I got 37/10 but then you can reduce it again to get 3.7. I hope this helps :)

The number of people who attended an art conference for five days was 42,27,35,39, and 96 . Describe the effect of the outlier on the mean and median

Answers

The solution is:

The outlier is 60.

The outlier is decreasing the value of Mean by = 87.8 - 60

= 27.8

The outlier is decreasing the value of Median by = 94 - 60 = 34

What is median?

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

Here, we have,

we are given that

Dukes science quiz scores are 99,91,60,94,and 95 .

we have been asked to describe the effect of the outlier on the mean and median.

Mean of the given data = 439/5

Mean of the given data= 87.8

Median of the given data after arranging in the ascending order 60,91,94,95,99 is 94.

The outlier is 60.

The outlier is decreasing the value of Mean by = 87.8 - 60

= 27.8

The outlier is decreasing the value of Median by = 94 - 60 = 34
