1.8x71

2.6x83

Answers

Answer 1

Answer:

1.8 x 71 = 127.8, just 18 x 71 = 1278, then count the the decimal place from the right, i.e 127.8

same for 2.6 x 83 = 215.8

.......ok try 5.52 x 5

Answer 2

Answer:

27,579.24 OR 343.6

Step-by-step explanation:

I don't know if this is what you mean but 1.8x71x2.6x83=27,579.24

Also, (if that was not what you meant), 1.8x71=127.8, 2.6x83=215.8, 127.8+215.8=343.6

In each case below, we describe a study to determine whether exercise helps increase certain mood enhancing chemicals in the brain. Indicate whether each describes an experiment or an observational study.
a). Using a random sample of 100 people, we randomly assign half of them to participate in a regular exercise program for a six-week period while the other half makes no changes. At the end of the time period, we measure the brain chemicals.
b). We contact a random sample of 100 people and record how much each person exercises and also measure the chemicals in the brain for each person.

Answers

Answer:

A)Experimental Study

B)Observational Study

Step-by-step explanation:

Observational Study : A study where researchers simply collect data based on what is seen and heard and infer based on the data collected.

Experimental Study: A study which involve the random assignment of -participants into different groups in order to determine the causal effect of a certain condition on a certain outcome .

A) In this case we are randomly classifying the subjects into two groups, where one group participate in a regular exercise program for a six week period, while the other half makes no changes. In this Part we are not observing the data . we are doing experiment over here and comparing those two different groups.

So, By definition It is an experimental study

B) In this case we are recording the data of each person and decision will be based on data

So, By definition It is an observational study

Answers

Answer:

1) 1/3

2) 45/99

3) 35/99

4) 24/99

5) 39/99

Explanation:

1) 0.333 = 0.333/1 = 0.999/3 ≈ 1/3

2) 0.454545 ; 100x ≈ 45.45 ; x ≈ 0.45 ; 45.45-.45 = 45 ; 100x-x = 99 ; x = 45/99

3) 0.354535 ; 100x ≈ 35.35 ; x ≈ 0.35 ; 35.35-.35= 35; 100x-x = 99x ; x = 35/99

4) 0.242424 ; 100x ≈ 24.24 ; x ≈ 0.24 ; 24.24-.24 = 24 ; 100x-x = 99x ; x = 24/99

5) 0.393939 ; 100x ≈ 39.39 ; x ≈ 0.39 ; 24.24-.24 = 24 ; 100x-x = 99x ; x = 39/99

How many subsets of 5 e elements can be made from a set of 7 elements?

Answers

Answer:

seems like this.

Step-by-step explanation:

From set theory, the factorial combinations are 2^N where N are the number of induvidual mambers of the set and that includes the null set. If we require that one element be the minimum to form a set, this eliminates the empty set (and there is only one empty set) so we must subtract one from the formula. The correct answer is therefore 2^N-1. In this case that is 2^5–1 = 31.

Answer:

Gina reads 30 pages per day.

Step-by-step explanation:

Check all true statements.
A. For all nonempty sets A, B, C, D, if A x B = C x D, then A = C and B = D.
B. For all sets A, B, the power set of the cartesian product of A and B is the cartesian product of the power sets of A and B. If A={1,2} and B={3} then A x B ={ {1,3}, {2,3} }.
C. The cartesian product has a cancellation property, i.e. if A x B = A x C for some sets A, B, C and A nonempty, then B = C. If A={1,2} and B={3} then A x B ={ (1,3), (2,3) }.
D. The cartesian product is symmetric, i.e. A x B = B x A for all sets A, B. For all sets A, B, the cardinality of A x B is the sum of the cardinalities of A and B.
E. The cartesian product is associative, i.e. (A x B) x C = A x (B x C) =for all sets A, B, C. Both sets are equal to A x B x C.
F. The cartesian product has a cancellation property, i.e. if A x B = A x C for some sets A, B, C, then B = C.

Answers

Step-by-step explanation:

the true statemnts underneath and are in bold letters

-.For all nonempty sets A, B, C, D, if A x B = C x D, then A = C and B = D.

This property is true

-The cartesian product has a cancellation property, i.e. if A x B = A x C for some sets A, B, C and A nonempty, then B = C.

This property is true

- If A={1,2} and B={3} then A x B ={ (1,3), (2,3) }.

if we have 2 non empty sets a and b if we want to get their cartesian product, it is defined as the set of all ordered pairs from a and b

we have A x B to be{(1,3)(2,3)}

therefore this is also true

Mark walked 12 1/2 miles in 5 hours. How many miles did Mark walk in 1 hour?

Answers

the answe is it is 2.5 or 2 1/2 as he said but in conclusion answe 2 1/2 or 2 and 1 half

Distance can be defined as how far a person or an object can go or cover.

The number of miles Mark walked in 1 hour is [tex]2\frac{1}{2}[/tex]  miles

From the question,

In 5 hours, Mark walked a distance of 12 1/2 miles.

Hence,

5 hours = [tex]12\frac{1}{2}[/tex]  miles

1 hour = ?

Cross Multiply

1 hour x [tex]12\frac{1}{2}[/tex]  miles / 5 hours

Solve the inequality: -2x + 5 ≥ 3x + 20
A) x ≤ 15
B) x ≤ 3
C) x ≥ 3
D) x ≤ -3

Answers

Answer:

D) [tex]x \leqslant - 3[/tex]

Explanation provided above.

The solution to the inequality -2x + 5 ≥ 3x + 20 is x ≤ -3.

Option D is the correct answer.

We have,

To solve the inequality -2x + 5 ≥ 3x + 20, we can follow these steps:

Subtract 3x from both sides to isolate the variable on one side:

-2x - 3x + 5 ≥ 3x - 3x + 20,

-5x + 5 ≥ 20.

Subtract 5 from both sides:

-5x + 5 - 5 ≥ 20 - 5,

-5x ≥ 15.

Divide both sides by -5.

Remember that when dividing by a negative number, the inequality direction flips:

(-5x) / (-5) ≤ 15 / (-5),

x ≤ -3.

Therefore,

The solution to the inequality -2x + 5 ≥ 3x + 20 is x ≤ -3.
