What is true about (0, 5)

My calculator says 97.5

Answer:

195/2

Step-by-step explanation:

60/8=15/2

15/2*13=195/2

Step-by-step explanation:

Geometric sequences are of the form a * b^x, where a and b are real constants.

We have a * b⁴ = 234 and a * b⁶ = 104.

Dividing the second equation by the first,

we get b² = 4/9, so b = 2/3.

When x = 4, a * b⁴ = 234.

=> a * (2/3)⁴ = 234, a = 1184.625

Hence the explicit rule

is a(n) = 1184.625 * (2/3)^n.

Answer:

Hence the explicit rule is a(n) 1184.625 *(2/3)^n.

According to the question, the function that has a factor of x - 7 is f(x) = x³ - 16x² + 53x+ 70

If x - a is a factor of a function f(x), then f(a) = 0

For x - 7 to be a factor of f(x), f(7) must be equal to zero.

For f(x) = x³ - 16x² + 53x+ 70

f(7) = 7³ - 16(7²) + 53(7) + 70

f(7) = 343 - 16(49) + 53(7) + 70

f(7) = 343 - 784 + 371 + 70

f(7) = 0

Since f(7) = 0 for f(x) = x³ - 16x² + 53x+ 70, x - 7 is a factor of f(x) = x³ - 16x² + 53x+ 70

Step-by-step explanation:

It's 87 feet I got the answer right

The  height of the tree is estimated as 87 ft.

The height of the tree can be estimated using trigonometric ratios. Therefore,

tan 44° = opposite / adjacent

tan 44° = h / 90

h = 90 tan 44°

h = 90 × 0.9656887748

h = 86.9119897326

h ≈ 87 ft

Therefore, the  height of the tree is estimated as 87 ft.

Answer:

0.9 miles per member

Step-by-step explanation:

Total distance = 9 miles

Number of members = 10

If they are to carry the food back for an equal distance, we have to fin

Distance covered by a person with the food pack = Total distance / Number of members

Distance covered by a person with the food pack = 9 / 10 = 0.9 miles per member

Answer:

1. It is not appropriate to use the normal curve, since np = 7.4 < 10.

2. The probability that more than 32% of the people in this sample have high blood pressure is 0.0033 = 0.33%.

Step-by-step explanation:

Binomial approximation to the normal:

The binomial approximation to the normal can be used if:

np >= 10 and n(1-p) >= 10

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Normal probability distribution

Problems of normally distributed distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

The proportion of U.S. adults with high blood pressure is 0.2. A sample of 37 U.S. adults is chosen.

This means, respectively, that [tex]p = 0.2, n = 37[/tex]

Is it appropriate to use the normal approximation to find the probability that more than 48% of the people in the sample have high blood pressure?

np = 37*0.2 = 7.4 < 10

So not appropriate.

It is not appropriate to use the normal curve, since np = 7.4 < 10.

Part 2:

Now n = 82, 82*0.2 = 16.4 > 10, so ok

Mean and standard deviation:

By the Central Limit Theorem,

Mean [tex]\mu = p = 0.2[/tex]

Standard deviation [tex]s = \sqrt{\frac{0.2*0.8}{82}} = 0.0442[/tex]

Find the probability that more than 32% of the people in this sample have high blood pressure.

This probability is 1 subtracted by the pvalue of Z when X = 0.32. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.32 - 0.2}{0.0442][/tex]

[tex]Z = 2.72[/tex]

[tex]Z = 2.72[/tex] has a pvalue of 0.9967.

1 - 0.9967 = 0.0033

The probability that more than 32% of the people in this sample have high blood pressure is 0.0033 = 0.33%.

Answer: $1166.91

Step-by-step explanation:

The following can be deduced from the question:

Average cost of an accident = $14,886.05

Probability of a driver getting into an accident = 7.1% = 7.1/100 = 0.071.

Overhead cost for insurance = $110

Therefore, the expected cost of an accident will be calculated as:

= Average cost of an accident × Probability of a driver getting into an accident

= $14,886.05 × 0.071

= $1056.91

Therefore, the driver's insurance premium will then be:

= $1056.91 + $110

= $1166.91

Answer:

Angle 1 = 22°

Angle 2 = 68°

Angle 3 = 68°

Angle 4 = 90°

Step-by-step explanation:

It is a rhombus by the definition:

A rhombus is a quadrilateral whose all four sides are equal in length and opposite sides are parallel to each other. However, the angles are not equal to 90°.

The properties of rhombus is:

(1) Opposite angles are equal

(2) All sides are equal and, opposite sides are parallel to each other

(3) Diagonals bisect each other perpendicularly

(4) Sum of any two adjacent angles is 180°

By property (3):

Angle 4 = 90°

By (1) and properties of isosceles triangle in the top right triangle:

Angle 2 = Angle 3 = 68°

In the top triangle:

Angle 1 + Angle 2 + 90° = 180° (Angle sum of triangle)

Angle 1 = 22°

Given:

Height of the cylinder = 21 ft

Dimeter of the cylinder = 10 ft

To find:

The volume of the cylinder.

Solution:

We have,

Dimeter of the cylinder = 10 ft

So, radius is half of diameter, i.e., 5 ft.

Volume of the cylinder is

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting [tex]\pi=3.14[/tex], r=5 and h=21, we get

[tex]V=(3.14)(5)^2(21)[/tex]

[tex]V=(3.14)(25)(21)[/tex]

[tex]V=1648.5[/tex]

Therefore, the volume of the cylinder is 1648.5 cubic ft.

The answer is D- A(x)=25+10x

Step-by-step explanation:

I cant really explain how i got the answer but i got it right

The function A(x) has greater value then F(x) for x = 2.5.

A function is a relation between a independent variable and a dependent variable such that the value of dependent variable depends upon the independent one.

Given are two functions of [x] as follows -

F(x) = 80 - 15x

A(x) = 25 + 10x

We have the following functions -

F(x) = 80 - 15x

A(x) = 25 + 10x

Now, we will evaluate each function at x = 2.5.

F(2.5) = 80 - 15 x 2.5 = 42.5

and

A(2.5) = 25 + 10 x 2.5 = 50

It can be seen that A(2.5) > F(2.5)

So, the function A(x) has greater value then F(x) at x = 2.5

Therefore, the function A(x) has greater value then F(x) for x = 2.5.

The required solution to the system of equations is (x, y) = (-2, 4). Option B is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
To solve this system of equations, we can set the two expressions for y equal to each other, since they both represent the same value of y,

x + 6 = -0.5x + 3

Simplifying and solving for x, we get:

1.5x = -3

x = -2

Now that we have the value of x, we can substitute it into one of the original equations to find the value of y. Using the first equation, we have,

y = x + 6

y = -2 + 6

y = 4

Therefore, the solution to the system of equations is (x, y) = (-2, 4).
