Answer:

that answer is 4

Step-by-step explanation:

divide the percent  by 40 and you get 4

Answer:

it is 4 dollars off

Step-by-step explanation:

40/10=4 and since it's 90% off, we multiply 4 x 9.

4 x 9 = 36. 40 - 36 = 4.

Answer:

variance = 1.66 hours

Step-by-step explanation:

It is given that,

The standard deviation from the National Health and Nutrition Survey is 1.29 hours.

We need to find the variance. We know that the relationship between the variance and the standard deviation is given by :

[tex]\text{Variance }=\text{standard deviation}^2\\\\\text{Putting all the values, we get :}\\\\\text{Variance }=(1.29)^2\\\\\text{Variance }=1.664\ \text{hours}[/tex]

or

Variance = 1.66

So, the variance is 1.66 hours.

I constructed line AD as a perpendicular bisector of line BC. Angles BDA and CDA are both 90 degrees because of the construction of a perpendicular bisector. Angles BDA and CDA are congruent because of the transitive property of equality.  Line BD is also equal to CD according to the definition of a perpendicular bisector. Triangles ABD and ACD are congruent by the angle side angle postulate. Since the parts of the congruent triangles are congruent, lines AB and AC are congruent.

The sides AB and AC opposite the congruent base angles of a triangle are congruent.

An isosceles triangle is a triangle with (at least) two equal sides. A polygon that consists of two equal sides, two equal angles, three edges, three vertices and the sum of internal angles of a triangle equal to 180°.

For the given situation,

Triangle ABC be an isosceles triangle.

∠ABC ≅ ∠BCA.

The diagram below shows an isosceles triangle ABC with AD is the perpendicular bisector of BC.

The perpendicular bisector AD divides the line BC as BD and DC.

Then, BD = DC.

We get triangles ΔADB and ΔADC,

AD = AD [∵ common side]

⇒ [tex]\angle ADB = \angle ADC=90[/tex]

Thus by ASA theorem,

The two triangles ΔADB and ΔADC are similar.

Then by CPCT theorem,

Side AB ≅ AC.

Therefore the sides AB and AC opposite the congruent base angles of a triangle are congruent.

Hence we can conclude that the sides AB and AC opposite the congruent base angles of a triangle are congruent.

Answer:

5

Step-by-step explanation:

In order to figure out average, we need to add up all the numbers. So adding 2, 4, 5, 6, and 8 gives us 25. We now divide that total by the total number of terms we used to reach 25. So since we had 5 numbers, we divide 25 by 5 to get an average of 5.

Answer:

5.

Step-by-step explanation:

To find mean. you just add all the numbers up and divide by the number of numbers (5).

2+4+5+6+8=25

25/5=5

Answer:

An easy way to solve this problem is divide $25.00 by 3 or $43.75 by 7. This number represents the amount of money he makes for 1 hour. So with that in mind, the correct equation is:

$8.33 = y

Answer:

Sally borrowed twenty-five dollars from Alex to buy a movie at the store. Later, she borrowed another thirty-five dollars to buy ride tickets at the state fair. How much money does she owe Alex?

Step by-step explanation:

When you have an even number of negative numbers in an equation, the answer will always be positive. When there's an odd number of negative numbers, the answer will be negative. For a problem like this, you can ignore the negative signs and focus on the numbers. 25+35 is 60, so Sally owes Alex 60 dollars.

Answer:

  y = -3/5x +27/5

Step-by-step explanation:

Since we want a parallel line, we can use the same x- and y-coefficients to find the new constant in the given form:

  -3(4) -5(3) = -12 -15 = -27

In the given form, the equation of the desired line is ...

  -3x -5y = -27

Solving for y, we have ...

  -5y = 3x -27

  y = -3/5x +27/5

The probability is  [tex]\frac{31}{365}[/tex]  , If an individual is selected at random have birthday in July  .

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]

According to the question

Total number  of days in year = 365

Total number of days in a leap year = 366

As, given  Ignore leap years

So, we will take days of years as 365 .

Now,

he or she has a birthday in July

i.e ,

It can be be happen any day of July

Total days in July = 31

Now,

Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]

substituting the value

Probability(Event) = [tex]\frac{Total\\\ day\\\ in\\\ July }{Total\\\ days\\\ in\\\ year}[/tex]

Probability(Event) = [tex]\frac{31}{365}[/tex]

Hence, If an individual is selected at random the probability have birthday in July  is  [tex]\frac{31}{365}[/tex]  .

Answer:

4, 1

Step-by-step explanation:

If you take 2, 8 and make it a ratio you get 2 : 8.

Then you turn 2 : 8 into 1 : 4. That is your answer for a mile.

For the other answer, you want to divide 2 by 8.

Step-by-step explanation:

35+64+97=196       97+64=161          161/196=B

The probability that a randomly-selected club member holds a brown belt or a purple belt is 0.821 which is nearest to 0.762.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total number of person = 35+64+97 = 196

P(brown belt) = 64/196  

P(purple belt) = 97/196    

Probability that a randomly-selected club member holds a brown belt or a purple belt:

= 64/196 + 97/196

= (64+97)/196

= 161/196 = 0.821

Thus, the probability that a randomly-selected club member holds a brown belt or a purple belt is 0.821 which is nearest to 0.762.

Answer:

What are the roots of the quadratic equation x²-81=0

Answer:

x = ± 9

Step-by-step explanation:

Given

x² - 81 = 0 ( add 81 to both sides )

x² = 81 ( take the square root of both sides )

x = ± [tex]\sqrt{81}[/tex] = ± 9
