If there are two children in the Patel family. They are twins of the same age. Then zero is  the range of their ages

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

There are two children in the Patel family.

They are twins of the same age.

Let x be the age of two children.

As they are twins so the age of children's is same.

The formula of range is highest minus lowest.

range = highest - lowest

Range=x - x

Range =0

Hence, the range of their ages is 0.

P(0.8<  p ^ <0.9)≈0.87

Step-by-step explanation:

The probability that the administrator's results are within 5 percentage points of the school board's 85% claim is approximately 0.919.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

To find the probability that the administrator's results are within 5 percentage points of the school board's 85% claim, we need to find the probability that the sample proportion of families sending their children to public school is between 80% and 90%.

We can use the normal approximation to the binomial distribution to calculate this probability. Since the sample size is large (n = 120) and the population proportion is not too close to 0 or 1 (p = 0.85), we can use the normal approximation.

The mean of the sampling distribution is the population proportion, which is 0.85 in this case. The standard deviation of the sampling distribution is given by the formula:

SD = √((p × (1 - p)) / n)

Plugging in the values, we get:

SD = √((0.85 (1 - 0.85)) / 120)

= √(0.01225 / 120)

= √(0.0001010417)

= 0.0101

Now we can use the normal distribution calculator to find the probability that the sample proportion is between 0.80 and 0.90. Plugging in the mean (0.85) and standard deviation (0.0101) and the upper and lower limits (0.80 and 0.90), we get a probability of 0.919.

Therefore, the required probability is approximately 0.919.

Answer:

50

Step-by-step explanation:

since all angles add up to 180

and since this is a right triangle the square in the corner is 90 degrees

so 40+90+x=180

130+x=180

subtract 130 from both sides

130-130+x=180-130

x=50

Step-by-step explanation:

Answer: The function is increasing in the given interval.

Step-by-step explanation:

The options are not given, so i will answer in a general way.

We have an exponential function g(x) such that:

g(3) = -53

and

g(5) = -41

From this we can only conclude that in the interval [3, 5] the function is increasing, because g(5) > g(3) and the general form of a exponential function is:

g(x) = A*(r)^x + C

Notice that we have two equations and 3 variables in the equation, this means that we can not find an exact solution for g(x) (we need the same number of independent equations than variables)

Then we can not conclude anything else for g(x)

Answer:

C) $3750

Step-by-step explanation:

We can start by calculating the down payment. To do this we can just simply calculate 25% of 3000, which equals 0.25*3000=7500. Now we can find out how much money it will cost to pay not including the down payment. $125 monthly for 2 years= $125 monthly for 24 months= 125*24= $3000. Finally we add the downpayment and the total cost of monthly payment to get $7500+$3000=$3750.

Design fee on each T-shirt = $5

We need to find the expression for the total cost. Let the total cost be y. So,

Let he has ordered x T-shirts. So,

y = 10x+5

Hence, this is the required solution.

Answer:

77°

Step-by-step explanation:

By the property of intersecting tangent and secant outside of a circle:

[tex]21 \degree = \frac{1}{2} ( 119 \degree - \widehat{SU} ) \\ \\ 42 \degree = 119 \degree - \widehat{SU} \\ \\ \widehat{SU} =119 \degree - 42 \degree \\ \\ \widehat{SU} =77\degree \\ \\ [/tex]

The mArc SU is option (B) 77 degrees

A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.

A secant is a line that intersects a circle in exactly two points.

Here,

By the property of intersecting tangent and secant outside of a circle:

[tex]T=\frac{1}{2}(RU-SU)[/tex]

Here

T= 21 degrees

RU is the mArc RU = 119 degrees

Then,

[tex]21 =\frac{1}{2}(119-SU)\\ 42=119-SU\\SU=119-42[/tex]

SU = 77 degrees

Hence, the mArc SU is option (B) 77 degrees

Answer: 30

Step-by-step explanation:

1. Use the Pythagorean theorem ([tex]A^{2} +B^{2} = C^{2}[/tex])

[tex]18^{2} +24^{2} =C^{2} \\324 + 576 = C^{2} \\900 = C^{2} \\\sqrt{900} = \sqrt{C^{2} } \\30 = C\\[/tex]

Step-by-step explanation:

so in this case, you use the pythagoras theorem:

since we don't have a hypotenuse, let's name is H

soo it will be

H= 18 squared + 24 squared

H = 324+ 576

H= 900

so you find the square root of 900 which is 30

so, therefore the answer is 30
