Answer: B.83

Step-by-step explanation:

The number 2,158 is called the numerator or dividend, and the number 26 is called the denominator or divisor.

The quotient of 2,158 and 26, the ratio of 2,158 and 26, as well as the fraction of 2,158 and 26 all mean (almost) the same:

2,158 divided by 26, often written as 2158/26. 2,158 divided by 26 = 83

The result of 2158/26 is an integer, which is a number that can be written without decimal places.

   2158 divided by 26 in decimal = 83

   2158 divided by 26 in fraction = 2158/26

   2158 divided by 26 in percentage = 8300%

The probability that the person uses exactly one of the facilities is 0.8.

Given that, there are 120 people in a sport center.

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

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Now, the person uses exactly one of the facilities

= 78+46+41-(21+16+24+9)

= 165-70

= 95

So, probability =95/120

= 0.8

Therefore, the probability that the person uses exactly one of the facilities is 0.8.

If p1, p2 and p3 are probabilities of surviving for years 1, 2 and 3 respectively, then the cumulative probability of surviving for 3 years is p1 + p2 + p3

The probability of surviving for 1 year = p1

The probability of surviving for 2 year = p2

The probability of surviving for 3 year = p3

The probability is the ratio of the number of favorable outcomes to the total number of outcomes.

The cumulative probability is defined as the probability distribution of random variables

The cumulative probability = p1 + p2 + p3

Therefore, the cumulative probability of surviving for 3 years is  p1 + p2 + p3

the answer is 5 and negative 2

The point H is at 2.5 on the number line

Here we know that point F is at 4 and point G is at -2.

The distance between these 2 points is

4 - (-2)

= 4 + 2 units

= 6 units.

Now let the point H be at x on the number line.

Now it is given that

FH:GH = 3:9

or, FH/GH = 3/9

or, (4 - x) / (x - (-2)) = 3/9

or, (4 - x)/(x + 2) = 1 /3

or, 12 - 3x = x + 2

or, 4x = 10

or, x = 2.5

What is a linear equation?

At first it is important to know about equation

Equation shows the equality between two algebraic expressions by connecting the two algerbraic expressions by an equal to sign.

A one degree equation is known as linear equation.

A linear equation needs to be solved here

Let the number of months for Belvedere to weigh the same as Thor be x months

Thor weighs 192 pounds and plans on losing 2.1 pounds each month.

Weight of Thor after x months = 192 - 2.1x

Belvedere weighs 211 pounds and plans on losing 7.5 pounds per month.

Weight of Belvedere after x months = 211 - 7,5x

By the problem,

The linear equation is

192 - 2.1x = 211 - 7.5x

7.5x - 2.1x = 211 - 192

Applying the sine ratio, the value of x is calculated as: x = 6.

The sine ratio is part of the trigonometric ratios that is used to solve a right triangle, which is expressed as:

sin ∅ = opposite side length / hypotenuse length

Given the following:

Apply the sine ratio to find the value of x:

sin 45 = 6√2/x

Multiply both sides by x

sin 45 × x = 6√2

Divide both sides by sin 45:

sin 45 × x / sin 45 = 6√2/sin 45

x = 6√2 / √2/2

x = 6√2 × 2/√2

Step-by-step explanation:

Divide 48 by 6

Part A) If the original price of the model car was $40, and it was sold on the third day, with a daily discount of 5%, the sales amount is $34.30.

Part B) The percentage discount from the original price is 14%.

The percentage discount is the total discount divided by the original price multiplied by 100.

In this instance, we compute the total discount as $5.70, then express this value as a numerator with $40 as the denominator.  The quotient is multiplied by 100.

Original price of the model car = $40

Daily discount = 5%

The date the car sells = the third day

The sales price on the third day = $34.30 ($40 x 95% x 95% x 95%)

Total discounts = $5.70 ($40 - $34.30)

Percentage discount for three days =14.25% ($5.70/$40 x 100)
