The difference of two numbers is 63. The sum of two numbers is 111. What are the two numbers?

Answers

Answer:

Step-by-step explanation:

Let b>a

b-a=63

b=63+a

a+b=111, substituting 63+a from above in this equation gives you

a+63+a=111

2a+63=111

2a=48

a=24, since b=63+a

b=63+24

b=87 so the two numbers are

24 and 87

I have 7 cups of yogurt give my sister 3 3/5 cup how yogurt remains?

Answers

Answer:

3 2/5 cups remaining

Step-by-step explanation:

To subtract fractions, they need a common denominator. I am using 5.

7 is equal to 35/5. Make 3-3/5 into an improper fraction of 18/5.

Now subtract: 35 - 18 = 17. There is 17/5 remaining.

Make it into a mixed number and you will get 3 2/5 remaining.

(hope this helps can i plz have brainlist :D hehe)

Step-by-step explanation:

Answer:

Step-by-step explanation:

I assume that they want the value of a when the solution exists.

2(ax+3y)+2x-6y=2(-5)+10

2ax+6y+2x-6y=-10+10

2ax+2x=0

ax+x=0

ax=-x

a=-1

You could then solve for x and y if you wanted x=5 and y=0

Unless a was a typo :)

What is range in statistics?

In statistics, the range of a set of data is the difference between the largest and smallest values, the result of subtracting the sample maximum and minimum. It is expressed in the same units as the data.

Given is a data set, we need to find the range of the data set,

S = 6.5, 7.6, 9.1, 2.4, 8.8​

The range = max value - min value

= 9.1 - 2.4 = 6.7

Hence, the range of the data set given is 6.7.

Previous studies reported that teenagers spent 8.5 hours per week, on average, on the phone. This mean is supposed to have increased, to test this hypothesis, a random sample of 500 teenagers were interviewed about how many hours per week they spent on their phones. The sample mean was 10.5 hours with a sample standard deviation of 2.35. Conduct a hypothesis test. The null and alternative hypotheses are:

Answers

Answer:

Since the calculated value of Z= 19.029 is much  greater than Z (0.05) = 1.645 and falls in the rejection region we reject the null hypothesis and conclude that mean of teenagers spending time on phone per week  has increased.

Step-by-step explanation:

1) Formulate the null and alternate hypothesis as

H0 : μ≤ 8.5  against the claim Ha:  μ > 8.5

2) Choose the significance level ∝ =0.05

3) The test statistic under H0  is

Z= x`-  μ/ s/√n

4) The rejection region is Z≥ Z(0.05)= 1.645

5) Computing the value of Z from sample information we get

Z= 10.5-8.5/ 2.35/ √500

Z= 2/ 2.35/ 22.361

Z= 19.029

Since the calculated value of Z= 19.029 is much  greater than Z (0.05) = 1.645 and falls in the rejection region we reject the null hypothesis and conclude that mean of teenagers spending time on phone per week  has increased.
