The mean of 17,x,10,17,51 is 21 find x

Answers

Answer:

x=10

Step-by-step explanation:

(17+x+10+51+17)/5=21

95+x=105

x=10

The required value of x for the given mean of the data is x = 10.

How to find the mean of the given sample of data?

In order to find the mean for a sample, first count the number of data in a sample, say n. Then, do the summation of all the values in that sample and divide it by the number of data obtained earlier.

Mathematically, it can be written for n number of data x₁, x₂, x₃, ..... as,

Mean = ( x₁ + x₂ + x₃ + .....)/n.

Given that,

The mean of 17, x, 10, 17 and 51 is 21.

It can be written in mathematical form as,

(17+ x + 10 + 17 + 51 )/5 = 21

=> 17+ x + 10 + 17 + 51 = 21 × 5

=> x = 105 - 95

=> x = 10

Hence, for the given data the value of x is 10.

Step-by-step explanation:

Assuming the rate is constant, the function will be ...

w = kt

We can find k using the given values:

11 = k·77

k = 11/77 = 1/7

The linear function rule is w = 1/7·t.

in a subway, x men and y women travel. explain what is meant by the expression: y-x

Answers

Answer:

Step-by-step explanation:

y - x means the the difference in the number of women compared with men.

So if there are 20 women and 14 men, y - x = 20 -1 4 = 6 , that is 6 more women than men.

If there are more men than women then y - x will have a negative value, and there will be, if we flip the above numbers. 6 more men than women.

Answers

2 − 3 = −5

First we need to Add 3 to both sides of the equation:

2 − 3 + 3 = −5 + 3

Then we simplify:

2 = −5 + 3

2 = −2

Now we divide both sides of the equation by the same term:

2 / 2 = −2 / 2

Final answer: = −1

I hope this helps!

Answer:

Y= - 1

Step-by-step explanation:

2y-3= - 5

+3 +3

2y= -2

/2 /2

Y= -1

Step 1: Add 3 to both sides because you want to cancel out the 3 so you do the opposite of what is say's. For example, if it says 2y-3 add 3 or 2y+3 subtract 3 from both sides.

Step 2: Add 3 to -5 which would be -2

Step 3: Since you're "multiplying" Y to 2 you're going to divide 2 to get Y by itself. So 2/2 cancels out and now you're left with y

Step 4: Divide 2 form -2 and you get -1

Is there a value of x that makes each of the following equalities true? If there is, find it.
a. √x-3=0
b. √x=-10
c. √x+1=0
d. √x=0.1

Answers

Step-by-step explanation:

a. √x - 3 = 0 ⇒ √x = 3 ⇒ x = 3² ⇒ x = 9 b. √x = -10,

no solution as √x is a positive value

c. √x+1=0 ⇒ √x = - 1,

no solution as √x is a positive value

d. √x = 0.1 ⇒ x = 0.1² ⇒ x = 0.01

√x-3=0x-3=0x=3

If square root is over x only x=3²=9

No solutions as -10 is <0

√x+1=0x+1=0x=-1

If root is over x only then no solutions

√x=0.1

x=0.01

What is the value of w in this equation?
10w = 27 + w

Answers

Answer:

w = 3

Step-by-step explanation:

10w = 27 + w

since there is two like terms in this equation which are 10w and w, we can subtract w from both sides to get it on one side of the equation

10w = 27 + w

-w - w

9w = 27

now we have to get w alone so we have to divide 9 by both sides

9w/9 = w

27/9 = 3

so w = 3

X=3

10w=27+w
-w

9w=27

spilled $40 into the ratio of 3:7

Answers

Answer:

$12/$28

Step-by-step explanation:

Let x and y represent the two amounts of money adding up to $40.

Assume that x is the smaller amount. Then:

x 3

----- = ----- Remembering that x + y = $40, we get x = $40 - y

y 7

amd sp we have

$40 - y 3

-------------- = ------ which, after cross-multiplication, is $280 - $7y = 3y

y 7

Simplifying this, we get $280 = 10 y, so that y must be $28. If y = $28, x must be $40 - $28, or $12.

$12

Then $40, split in the ratio 3/7, is the ratio ----------------

$28

Check: Note that $12 + $28 = $40, as required, and that $12/$28 = 3/7.

Answer:

-1/28

Step-by-step explanation:

You need to convert 2/7 and 1/4 into the same denominator. The GCD is 28. 2/7=8/28 and 1/4=7/28. 7/28-8/28=-1/28

Answer:

-1/28

Step-by-step explanation:

You have to find the least common multiple for 7 and 4, the denominators, to add the fractions. The LCM of 7 and 4 would be 28. You would have to multiply 7 by 4 and 4 by 7, meaning you have to multiply the numerators by the same number. 1x7/4x7-2x4/7x4= -1/28.

Mrs. Janssen has a class of 10 students. In her class, there are 4 boys and 6 girls. Mrs. Janssen chooses two students from her class randomly.
What is the probability that she did NOT choose a boy either time?

Answers

Probabilities are used to determine the chance of events

The probability that she did NOT choose a boy either time is 1/3

The given parameters are given as:

[tex]\mathbf{n = 10}[/tex] --- total number of students

[tex]\mathbf{Boys = 4}[/tex] --- total number of boys

[tex]\mathbf{Girls = 6}[/tex] ---- total number of girls

If she did not choose a boy in either selection, then it means that both selections are girls.

So, the probability is calculated using:

[tex]\mathbf{P = P(Girl) \times P(Girl)}[/tex]

The selection is without replacement.

So, we have:

[tex]\mathbf{P = \frac{Girl}{n} \times \frac{Girl-1}{n-1}}[/tex]

Substitute known values

[tex]\mathbf{P = \frac{6}{10} \times \frac{6-1}{10-1}}[/tex]

[tex]\mathbf{P = \frac{6}{10} \times \frac{5}{9}}[/tex]

Simplify

[tex]\mathbf{P = \frac{1}{3}}[/tex]

Hence, the probability is 1/3
