For number 19 I don’t get it, there’s nothing wrong with it(i think) please help me

Answers

Answer 1

-7/11 is not -.63 with the three repeating

If u put it into a calculator it is -.63636363
( so the line should be over both the 6 and the 3, because that is what is repeating)

Answer 2

The repeating sign is just over the 3 and needs to be of the 6 and the 3

Marion Middle School has 600 students. Mike surveys a random sample 7 of 30 students and finds that 7 of them play a musical instrument. How many students at the school are likely to play a musical instrument?

Please explain how as well.

Answers

So if 7/30 students plays an instrument then you'll need to set up an equation for this. The equation you'd use would be:
7/30 = x/600
Then, cross multiply to get:
30x = 4200
Lastly, divide each side by 30 and:
x = 140 students play a musical instrument

Hope this helps!! :)

Do a proportion
7/30=x/600
1. Cross multiply
7x600=4200
30•X= 30x
30x=4200
Divide each side with the number with the variable.
30x/30=4200/30
X=140

Which expression represents this word phrase? seven less than the quotient of x and 9 x−7 9 x÷ 9 7 (x÷9)−7 (9÷x)−7

Answers

The expression that represents 'seven less than the quotient of x and 9' is written as (x / 9) - 7, translating the operations of division and subtraction from the word phrase to algebra.

The word phrase 'seven less than the quotient of x and 9' translates to an algebraic expression by identifying the key terms: 'quotient' refers to division, while 'less than' indicates subtraction.

Specifically, the quotient of x and 9 is expressed as (x \/ 9), and to represent 'seven less than' this quotient, we subtract 7 from it. Thus, the corresponding mathematical expression is (x \/ 9) - 7.

I would turn these into fractions. So you do 4 times denominator and then add numerator. Do the same for the other fraction. Afterwards you get 17/4*8/3, which should give you your answer if I'm not mistaken, but I'm not 100% sure on that.

A trick coin is made such that when it is tossed there is a 20% chance of heads landing face up and an 80% chance of tails landing face up. If the coin is tossed twice, what is the probability that the coin will land with heads facing up both times?

Answers

P( heads on one toss) = 0.20

P ( 2 heads) = 0.20 * 0.20 = 0.04 or 4%

Answer: 4 %

Step-by-step explanation:

According to the question,

20% chance of heads landing face up

Therefore, probability of getting a head, [tex]P(H) = \frac{20}{100} = \frac{1}{5}[/tex]

The probability of getting tail, [tex]P(T) = \frac{80}{100} = \frac{4}{5}[/tex]

Thus, the probability that the coin will land with heads facing up both times

= [tex]\frac{1}{5}\times \frac{1}{5}[/tex]

= [tex]\frac{1}{25}[/tex]

= 0.04 or 4 %

Thus the required probability is 4 %.

The last calculator correctly shows (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

What are some rules of exponents?

Some common rules of exponents are

a^b/a^c = a^(b - c),

a^b.a^c = a^(b + c).

We can only add and subtract exponents only when we have the same base.

Given, (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

Here we have base 10 raised to some power.

So, (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

= (6.47×10⁻¹⁵⁻⁽⁻²⁹⁾)/(3.36).

= (6.47×10⁻¹⁵⁺²⁹⁾)/(3.36).

= (6.47×10¹⁴)/(3.36).

So, the last calculator correctly shows (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

The property of one permits you to multiply or divide the numerator and denominator of a fraction by the same number without changing the value of the fraction. Is there a property of one for addition? Support your answer using examples

Answers

There is not a property of "1" for addition, but the identity property in this case uses "0" instead. If a number is increased by 1, the value will necessary be increased or decreased by the amount added or subtracted. However, if the number either adds or subtracts zero, then value will be left unchanged. Examples: 3+1 = 4, but 3+0 = 3,

1st game was 42 minutes....2nd game was 5/3 times longer....so we multiply

5/3 * 42 = (5 * 42)/3 = 210/3 = 70 minutes....so the 2nd game was 70 minutes or 1 hr and 10 minutes

42 x 5/3= 70

Find the outlier of the set of data 80,71,75,69,74,17,82

Answers

17 is the outlier because it is not very close to the other numbers

Answer:

The Outlier is 17.

Step-by-step explanation:

Since 17 is far from other numbers of data set. So, it is an outlier.

Also all other numbers in the data set lie between 69 to 82. But 17 is distinct from other numbers. Hence it is an outlier.

Further, Outlier is the observation which is distinct or has a large distance from other observation. Also, Data set is much affected by the outliers.

A student applies for a summer internship at different companies. Given this student's previous work experience and grades, there is a chance of getting an internship offer at any company. Getting an offer from one company does not affect getting an offer from another company. What is the probability this student will receive or more offers?

Answers

Given that a student applies for a summer internship at 5 different companies. Given this student's previous work experience and grades, there is a 40% chance of getting an internship offer at any company. Getting an offer from one company does not affect getting an offer from another company.

What is the probability this student will receive 2 or more offers? (Round to 3 decimal places.)

This situation describes a binomial distribution with the probability of success = 40% = 0.4 and the number of trials = 5.

P(2 or more offers) = P(2) + P(3) + P(4) + P(5) = 1 - [P(0) + P(1)]

The binomial probability is given by

[tex]\bold{P(x)=\ ^nC_xp^x(1-p)^{(n-x)}} \\ \\ \bold{P(0)}=\ ^5C_0(0.4)^0(1-0.4)^{(5-0)} \\ \\ =1\times1\times(0.6)^5=0.07776 \\ \\ \bold{P(1)}=\ ^5C_1(0.4)^1(1-0.4)^{(5-1)} \\ \\ =5\times0.4\times(0.6)^4=2\times0.1296 \\ \\ =0.2592 \\ \\ \bold{P(0)+P(1)}=0.07776 + 0.2592=0.33696 \\ \\ \bold{\therefore P(2\ or\ more\ offers)}=1-[P(0)+P(1)] \\ \\ =1-0.33696=0.66304[/tex]

Therefore, the probability this student will receive 2 or more offers is 0.663 to 3 decimal places.

twenty-five is the quotient of a number y and 3.5 (write as algebraic expression)

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as (y / 3.5) = 25.

An explanation of an algebraic expression representing the quotient of a number y and 3.5.

The student is asking to express the statement "twenty-five is the quotient of a number y and 3.5" as an algebraic expression. In algebraic terms, the quotient of y divided by 3.5 is represented by[tex](\frac{y}{3.5})[/tex]or (y / 3.5).

Therefore, the complete algebraic expression that represents this statement is (y / 3.5) = 25.

The algebraic expression for 'twenty-five is the quotient of a number y and 3.5' is 25 = y / 3.5. To find y, you multiply 25 by 3.5.

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as 25 = y / 3.5.

To solve for y, you would multiply both sides of the equation by 3.5 to isolate y. This would give you: y = 25 x 3.5.
