The radius and diameter for the given figure are.

What is diameter?

In pure mathematics, a diameter of a circle is any line phase that passes through the middle of the circle and whose endpoints lie on the circle. It can even be outlined because the longest chord of the circle.

Main body:

A) as radius given = 3yd

so diameter = 2r

diameter = 2*3

                = 6 yd

B) diameter given = 92 in

as d = 2r

92 = 2r

r = 46 in

C) as radius given = 23 ft

so diameter = 2r

diameter = 2*23

               = 46 ft

Hence the values are as follows.]

Answer: 2.35%, 2.3, [tex]2\frac{1}{3}[/tex], [tex]\frac{25}{9}[/tex]

Explanation:

0.235 (23.5%) is the least

2.3 (the actual decimal in the entire group) is the second least

2.33 ([tex]2\frac{1}{3} =\frac{7}{9}[/tex] as an improper fraction and [tex]\frac{7}{9} = 2.33[/tex]is the third least

2.78 ([tex]\frac{25}{9}[/tex] is already an improper fraction. In decimal version, it is 2.78) is the greatest.

Choices:

A) 2x + 10 = 4x - 30

B) angle A+ angle B+ angle C+ angle D=180°

C) angle A+ angle B+ angle C+ angle D=360°

D) AB = CD

Find the value of x:

Find the measure of angle DAB:

Correct choice is A.

Answer:

Step-by-step explanation:

1) Finding the incorrect option?

The incorrect statement is,

→ angle A+ angle B+ angle C+ angle D=180°

(Because, A + B + C + D = 360°)

Hence, option (b) is the answer.

2) Solving for angle DAB?

Forming the equation,

→ 2x + 10 = 4x - 30

Now the value of x will be,

→ 2x + 10 = 4x - 30

→ 2x - 4x = -30 - 10

→ -2x = -40

→ x = -40/-2

→ x = 40/2

→ [ x = 20° ]

Then value of angle DAB is,

→ A = 2x + 10

→ A = 2(20) + 10

→ A = 40 + 10

→ [ A = 50° ]

Hence, option (a) is correct.

The required equation of the line is y = -(0.5)x + 225 expressed in slope-intercept form.

Let x represent the number of months Jason's gift card has been inactive after 1 year and let y represent Jason's card balance.

We take the two points (0, 225) and (1, 224.5) in the given table.

The required equation of the line is

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = 0, y₁ = 225

x₂ = 1, y₂ = 224.5

Substitute values in the equation, we get

y - 225 = (224.5-225 /1-0)(x - 0)

y - 225 = -(0.5)x

y = -(0.5)x + 225

Therefore, the required equation of the line is y = -(0.5)x + 225.

The answer of how many filter has he not posted is 60, using fraction.

What is a fraction?

If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.

Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.

John has 96 fliers

He post 1/4 of fliers so 96*1/4=24

So left post will be 96-24 = 72

So post 1/6 of remaining so 72*1/6=12

72-12=60

The binomial distribution in 3 decimal place value is 0.294

Binomial distribution:

Binomial probability distribution determines the probability of a discrete random variable that results from an experiment in which there are two possible independent outcomes and which is repeated n times.

The calculation formula is:

[tex]P(X) = \binom{n}{X} \cdot p^X \cdot (1-p)^{n-X}[/tex]

where

n  is the number of trials,

p  is the probability of success on a single trial, and

X  is the number of successes.

Given,

Here we have the following values,

n = 8

p = 0.2

Here we need to find the value of p(X = 2)

Here we know the values of

number of trials = 8

probability of success = 0.2

And the number of success = 2

Then the binomial distribution is calculated by applying these values on the formulas, then we get,

[tex]P(2) = \frac{8!}{2!(8-2)!} \cdot 0.2^2 \cdot (1-0.2)^{8-2}[/tex]

When we evaluating the expression, we have

P(2) = 0.29360128

Therefore, the resulting value is P(2) = 0.29360128

When we round of t into 3 decimal places then we get the value 0.294.

The probability that a patient with a negative result is truly HIV-free is 0.999.

To find the probability that confirms that the result of the HIV test is negative, we must take into account the information provided in the information and perform the following mathematical operation.

The probability that No HIV and test positive is:

P = 0.85 * 0.985

P = 0.8372

The probability that HIV and test negative is:

P = 0.15 * 0.003

P = 0.00045

The probability that No HIV and negative test of HIV and negative test is:

P = 0.00045 + 0.8372

P = 0.8377

P = (NOT HIV / Test)

P = 0.8372 / 0.8377

P = 0.999

The three angles of the triangles are ∠A= 60°, ∠B = 75° and ∠C = 45°.

What is are of triangle?

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.

The sum of all angle of triangle = 180

The ∠5y + ∠7y = 180

∠12y = 180

y = 180/12 = 15

Hence the ∠CBA = 75° AND ∠ACB = 45°.

Now ∠A + 75+45 = 180

∠A = 180-120 = 60°

Hence, the three angles of the triangles are ∠A= 60°, ∠B = 75° and ∠C = 45°.

ANSWER:

The equation used to represent the situation is 3x + 4y = 39.53, and Caroline spent 6.29 per lipstick.

EXPLANATION:

We will use x for eyeshadow and y for lipstick.

The equation would be: 3x + 4y = 39.53

3(4.79) + 4y = 39.53

14.37 + 4y = 39.53

14.37 - 14.37 + 4y = 39.53 - 14.37

4y = 25.16

4y / 4 = 25.16 / 4

y = 6.29

Check.

3x + 4y = 39.53

3(4.79) + 4(6.29) = 39.53

39.53 = 39.53

The Rogers family's sprinkler worked for 25 hours and Walker family's sprinkler worked for 20 hours

The water output rate of Roger's family's sprinkler = 30 liter per hour

The water output rate of Walker family's sprinkler = 20liter per hour

Total number of hours combined = 45 hours

Consider the number of hours that Rogers family's sprinkler work = x

The number of hours that Rogers family's sprinkler work  = y

Then the equation will be

x  + y = 45

x = 45 -y

Total water output = 1150 liters

30x + 20y = 1150

Here we have to use substitution method

30(45-y) + 20y = 1150

1350 - 30y + 20y = 1150

1350 - 10y = 1150

10y = 1350 - 1150

10y = 200

y = 200/10

y = 20 hours

Then,

x = 45 - y

x = 45 - 20

x = 25 hours

Hence, the Rogers family's sprinkler worked for 25 hours and Walker family's sprinkler worked for 20 hours
