A set of exam marks has mean 70 and median 65 marks. It is decided to subtract 10 from all the marks. For the new set of marks, what is the median?

Answers

Answer 1

Answer:

For the new set of marks, the median is of 55

Step-by-step explanation:

The median is the halfway point of a dataset, that is, the value that separates the lower 50% of the data set from the upper 50%.

In a data set, if we subtract or add all marks by x, the median will be subtracted or added by x.

In this question, we have that:

Median 65

From all marks, 10 is subtracted.

So, for the new set of marks, the median is of 65 - 10 = 55

find slope of the graph 9x-3y=15

Answers

ExplanationConvert the equation into slope-intercept form.

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

[tex]9x - 3y = 15 \\ 9x - 15 = 3y \\ \frac{9x - 15}{3} = y[/tex]

Simplify

[tex] \frac{9x}{3} - \frac{15}{3} = y \\ 3x - 5 = y \\ y = 3x - 5[/tex]

From y = mx+b, the slope is 3.

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have budgeted $3500 for the reception. If the reception hall charges a $50 cleanup fee plus $34 per person find the greatest number of people that they may invite and still have within their budget.

Answers

Answer: See Below

Step-by-step explanation:

Create the equation:

$34 times the number of people plus the $50 cleaning fee has to be less than or equal to $3500

Or

34p + 50 <= 3500

34p <= 3450

p <= 101.470588....

We can have a part of a person attending the reception so we have to drop the remainder/decimal. Therefore the most amount of people that can attend the party and stay within budget is 101.

Find three consecutive integers such that the sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.

Answers

Answer:

12,13 and 14

Step-by-step explanation:

Let the three consecutive integers be n, n+1 and n+2

ATQ,

The sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.

[2(n+1)+4(n+2)] = 7n-2

or

2n+2+4n+8=7n-2

Taking like terms together,

6n-7n = -2-8-2

n = 12

So,

First integer = 12

Second integer = 12+1 = 13

Third integer = 12+2 = 14

Hence, three consecutive integers are 12,13 and 14.

A container is 8/9 kg of berries is 2/3 full, how many kg can the container hold

Answers

Answer:

1.33kg of berries

Step-by-step explanation:

A container is 8/9 kg of berries is 2/3 full, how many kg can the container hold

2/3 of a container = 8/9kg

To get the amount of kg the container can hold, we will write;

1 container = x kg

Divide both expressions

2/3 = 8/9x

Cross multiply

2 * 9x = 3*8

18x = 24

x = 24/18

x = 1.33kg

Hence the container will hold 1.33kg of berries

A large sleep study involving over 5000 American teenagers examined how many hours the participants slept on the weekend. The nightly sleep times were distinctly non-normal with a mean of 10 hours and a standard deviation of 2 hours. Suppose we take a random sample of 100 nightly sleep times from this population. We can assume that the times in the sample are independent. What is the probability that the mean of these 100 sleep times is farther than 0.4 hours away from the population mean?
a) 0455
b) .02
c) 1
d) .02275

Answers

Answer:

.05

Step-by-step explanation:

Khan

Using the normal distribution and the central limit theorem, it is found that the probability that the mean of these 100 sleep times is farther than 0.4 hours away from the population mean is:

a) 0.0455

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean.  After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sample means of size n, as long as n > 30, is approximately normal and has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem:

Mean of 10 hours, hence [tex]\mu = 10[/tex].Standard deviation of 2 hours, hence [tex]\sigma = 2[/tex].Sample of 100, hence [tex]n = 100, s = \frac{2}{\sqrt{100}} = 0.2[/tex].

We want the probability that the mean is farther than 0.4 hours away from the population mean, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{0.4}{s}[/tex]

[tex]Z = \frac{0.4}{0.2}[/tex]

[tex]Z = 2[/tex]

The probability is P(|Z| > 2), which is 2 multiplied by the p-value of Z = -2.

Z = -2 has a p-value of 0.0275.2 x 0.0275 = 0.0455

Hence, option A is correct.

Step-by-step explanation

PEMDAS is key to solving. First you multiply 4*5 because its the first parenthesis we see, to get 20. Next we see that 1-2 is in a different parenthesis, so we get -2. So our current equation is 20-10-2-1+5. You just add/subtract in that order. 20-10=10 10-2=8 8-1=7 7+5=12 So your final answer is 12.

The number of bees in a hive doubles every year. A farmer starts a hive with 100 bees. After y years, the hive will contain B bees, where B = 100 · 2ʸ. How many bees will be in the hive after 3 years, assuming the hive continues to grow at this rate? (Answer must be in a complete sentence). *

Answers

Answer:

800 bees.

Step-by-step explanation:

If he starts with 100, after a year, it's 200, after another year, it's 400, and after a third year, it's 800.

It will be 800 bees in the hive after 3 years, assuming the hive continues to grow at this rate.

What are exponents?

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

We are given that number of bees in a hive doubles every year. A farmer starts a hive with 100 bees.

After y years, the hive will contain B bees, where;

B = 100 · 2ʸ.

Therefore, after 3 years,  it will be;

B = 100 · 2³

B = 100 x 8

B = 800

Hence, It will be 800 bees in the hive after 3 years, assuming the hive continues to grow at this rate.
