Where is the answer to the expression 5 - 9 located on a horizontal number line?
O 9 units to the left of 5
09 units to the right of 5
4 units to the right of 5
4 units to the left of 5

Answers

Answer:

A 09 units to the left of 5.

Step-by-step explanation:

The reason this is the answer is because going left on the number line signifies subtraction (down) and with 5 being your starting number you would be going down (left) the number line by 9

In one study, researchers at a clinic looked at more than 120,000 patients enrolled in 14 international studies in the past 10 years. Among the patients with heart problems, researchers found at least one risk factor in 84.7% of the women and 80.7% of the men. If a woman is selected at random from the women with heart problems, what is the probability she has none of the risk factors? Write your answer as a percentage. % If a man is selected at random from the men with heart problems, what is the probability he has none of the risk factors? Write your answer as a percentage. %

Answers

Answer:

The probability she has none of the risk factors  [tex]P(N) =  15.3 \%[/tex]

The probability he has none of the risk factors [tex]P(M) =  19.3 \%[/tex]  

Step-by-step explanation:

From the question we are told that

    The  number of patients enrolled is  n  =  120,000

    The  number of international  studies is  N  =  14

    The  number of years is  y  =  10 years

    The risk  factor for  women  is  r = 84.7%

     The  risk factor for men is  R =  80.7%

     

Generally the probability that she has none of the risk factors is mathematically represented as

     [tex]P(N) =  100 - r)\%[/tex]

=>    [tex]P(N) =  100 - 84.7)\%[/tex]

=>    [tex]P(N) =  15.3 \%[/tex]  

Generally the probability that he has none of the risk factors is mathematically represented as

          [tex]P(M) =  100 - R)\%[/tex]

=>    [tex]P(M) =  100 -  80.7)\%[/tex]

=>    [tex]P(M) =  19.3 \%[/tex]

Choose the system of inequalities that best matches he graph below.

Answers

Answer:

y<-2/3x. y< x-3

Step-by-step explanation:

y ≤ - (2/3)x and y < x - 3 are the system of inequalities that best matches he graph below.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

First, we can see that for both of the inequalities the shaded part is below the lines.

You also can see that the solid line (correspondent to the symbol ≤) is the one with a negative slope, and the dashed line (correspondent with the line <) is the one with a positive slope.

Only with that, we conclude that the correct option is B.

y ≤ - (2/3)x

y < x - 3

Hence, y ≤ - (2/3)x and y < x - 3 are the system of inequalities that best matches he graph below.

10 – 2(3x – 1) > 6x + 10


Pls solve with steps and explain

Answers

Answer:

x < 1/6

Step-by-step explanation:

In the equation 10 – 2(3x – 1) > 6x + 10, start by using the distributive property. Once you've done that, you'd now get 10-6x+2 > 6x+10.

Now, add 10 and 2 togther to get -6x+12 > 6x+10.

Subtract 6x to both sides and subtract 12 to both sides and now you'll get

-12x > -2.

Now, divide each side by -12 to get x < 2/12 or 1/6. Notice how the sign is flipped since you divided by a -.

10-2(3x-1)>6x+10
10-6x+2 > 6x+10
10+2> 12x+10
12> 12x+10
2> 12x
1/6>x

Triangle X Y Z is shown. Angle X Z Y is a right angle. The length of Z X is b, the length of Z Y is a, and the length of hypotenuse X Y is c.
Given right triangle XYZ, which correctly describes the locations of the sides in relation to ∠Y?

a is opposite, b is adjacent, c is the hypotenuse
a is the hypotenuse, b is opposite, c is adjacent
a is adjacent, b is the hypotenuse, c is opposite
a is adjacent, b is opposite, c is the hypotenuse

Answers

Answer:

C. A is adjacent, B is opposite, C is the hypotenuse

The locations of the sides in relation to ∠Y are that a is adjacent, b is opposite, and c is the hypotenuse. The correct answer would be an option (D).

What is the right triangle?

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

In the right triangle XYZ we have

The legs are represented by sides a and b, whereas the hypotenuse is represented by side c. (the greater side)

Angle Y's adjacent side is side a, while angle X's opposite side is side b.

Side b is the opposing side of angle Y and next to angle X.

The hypotenuse is represented by side c.

Because the angles X and Y are complementary, their total equals 90 degrees.

Therefore, we can conclude that a is adjacent, b is opposite, and c is the hypotenuse.

Hence, the correct answer would be an option (D).

If all of the dimensions in a cone increase by a factor of 5. How many times greater is the volume?​

Answers

Answer:

125 times bigger.

Step-by-step explanation:

A great way to visualize this problem is to think of it as a volume problem itself. Another good way to think about it is to plug in numbers in its place.

Way #1

5*5*5 (or 5^3)=125

Way #2

(2*2*2)=8

(2*5)*(2*5)*(2*5)=1000

Need help please, 30 points: Rewrite the expression with a rational exponent as a radical expression. five to the three fourths power all raised to the two thirds power the cube root of five squared the twelfth root of five the square root of five the cube root of five the fourth power

Answers

Correct arrangement of the question is;

Rewrite the rational exponent as a radical: five to the three fourths power all raised to the two thirds power

A) the cube root of 5 squared

B) the twelfth root of 5

C) the square root of 5

D) the cube root of 5 the fourth power

Answer:

Option C) the square root of 5

Step-by-step explanation:

We are given: five to the three fourths power all raised to the two thirds power

Translating that statement means 5 is raised to ¾ raised to ⅔.

In indices, when we have two powers attached to a number, the two powers will multiply each other.

Thus, 5 is raised to; ⅔ × ¾ = 2/4 = ½

Thus, 5 is raised to power ½.

Now, when a number is raised to the power ½, it is said to be square root of that number.

Thus, the right answer is square root of five.

Chester Boles reviewed his credit card's monthly statement. It shows a $2,376.10 previous balance and this month's new purchases of $875.22, $65.75, $45.22, and $21.23. It also shows a $875.22 credit and a $45.30 finance charge. He also made the minimum payment of 2.5% of the previous balance. What is the new balance?

Answers

The new balance after considering the new purchases, credits, finance charge, and minimum payment is $2,494.20.

Here,

To calculate Chester Boles' new credit card balance, we need to take into account the previous balance, new purchases, credits, and finance charge, as well as the minimum payment.

Add up the new purchases:

$875.22 + $65.75 + $45.22 + $21.23 = $1007.42

Add up the credits:

$875.22 (credit)

Calculate the total balance before the finance charge:

Previous Balance + New Purchases - Credits

$2,376.10 + $1007.42 - $875.22 = $2,508.30

Add the finance charge:

Total Balance + Finance Charge

$2,508.30 + $45.30 = $2,553.60

Calculate the minimum payment:

2.5% of the previous balance:

2.5% * $2,376.10 = $59.40

Subtract the minimum payment from the total balance:

$2,553.60 - $59.40 = $2,494.20

The new balance after considering the new purchases, credits, finance charge, and minimum payment is $2,494.20.
