Help, Please! I really need this done right Carlos is analyzing the results of an experiment on two groups of mice in which he c

ompared the difference in their weight gain after feeding each group a different type of food for one month. The difference in the mean weight gain is 0.6 grams. The standard deviation of the difference in sample means is 0.305. The 68% confidence interval for the population mean difference is ±(A.0.305, B.0.600, C.0905 D.1.200) The 95% confidence interval for the population mean difference is ±(A.0.160,B.0.305,C.0.610,D.0.915)

Given:
difference in the mean weight gain is 0.60 grams
standard deviation of the difference in sample mean is 0.305

68% confidence interval for the population mean difference is a) 0.305

0.60 <u>+</u> 1 * 0.305
0.60 + 0.305 = 0.905
0.60 - 0.305 = 0.295

95% confidence interval for the population mean difference is c) 0.61

0.60 <u>+</u> 2 * 0.305
0.60 + 0.61 = 1.21
0.60 - 0.61 = -0.01

Answer:

B and E

Step-by-step explanation:

A. -7 ÷ (-4) = -7/-4 = 7/4 = 1.75

B. -(3 ÷ 2) = -(1.5) = -1.5

C. -8/5 * (-5/8) = (8/5) * (5/8) = 1

D. -5/-3 = 5/3 ≈ 1.667

E. -9 ÷ 6 = -9/6 = -1.5

If 332 students brought shirts and there are 830 students at the school what percents of the student brought shirts
Anika [276]

Answer: 40%

Step-by-step explanation: What I like doing with problems like this is work backward, so that is how this explanation is going to work.

830*0.40=332 so that is how I got 40% now lets dig a little deeper.

How to find percent is take the whole and times it by the decimal of percent you want (eg. if 400 is my whole I want to find out what 30% of it is I would do 400*0.30)

So then we take our 830 times it by what we think best fits and that's how I solved it!

If you need any further help let me know!

If f(x) = 5x 6 and g(x) = x2 - 4x-8, find (f+ g)(x).
vredina [299]

The value of (f + g)(x) is x² + x - 14

Given: f(x) = 5x - 6

g(x) = x² - 4x - 8.

To find the value of (f + g)(x)

What are functions?

Functions are expressions or a rule that defines the relation between different variables which are described for a given problem.

Let's solve the question:

f(x) = 5x - 6

g(x) = x² - 4x - 8

We know from the algebra of functions that:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = (5x - 6) + (x² - 4x - 8)

Now grouping like terms:

= x² + (5x - 4x) + (-6 - 8)

= x² + x - 14

Therefore, (f + g)(x) is x² + x - 14

Hence the value of (f + g)(x) is x² + x - 14
