Please what is the answer to this question
2^2x–4^x+16​

The equation for a multiple regression model with p predictor variables (x1, x2, ..., xp) and a response variable (y) can be written as:

y = β0 + β1*x1 + β2*x2 + ... + βp*xp + ε

In this equation:

- y represents the response variable (the variable we are trying to predict).

- β0 represents the y-intercept or the constant term.

- β1, β2, ..., βp represent the coefficients or weights associated with each predictor variable (x1, x2, ..., xp).

- x1, x2, ..., xp represent the predictor variables.

- ε represents the error term or residual, which accounts for unexplained variation in the model.

The multiple regression model aims to estimate the relationship between the predictor variables and the response variable by finding the best-fitting values for the coefficients β0, β1, β2, ..., βp.

2.23% is the probability of a city with a population of 200,000, and there will be exactly 2 accidental drownings per year.

The Poisson distribution, is useful for modeling the number of events (in this case, accidental drownings) in a fixed interval (here, a year). Given the average rate of 3.0 drownings per 100,000 people per year, we first need to find the expected number of drownings in a city with a population of 200,000.

Expected drownings per year = (3.0 drownings / 100,000 people) * 200,000 people = 6 drownings

Now, we can use the Poisson probability formula to calculate the probability of exactly 2 accidental drownings per year in this city:

P(X = k) = (λ^k * e^(-λ)) / k!

Here, X represents the number of drownings, k is the desired number of drownings (2 in this case), λ (lambda) is the expected number of drownings per year (6), e is the base of the natural logarithm (approximately 2.718), and k! is the factorial of k.

P(X = 2) = (6^2 * e^(-6)) / 2! = (36 * e^(-6)) / 2 = (36 * 0.002478) / 2 = 0.04461 / 2 = 0.022305

Therefore, the probability that in a city with a population of 200,000, there will be exactly 2 accidental drownings per year is approximately 0.0223 or 2.23%.

Answer:

-10x^2+4x-8   im 75% sure

Step-by-step explanation:

The tοtal area οf the figure is 2x (area οf right angle triangle) + area οf rectangle + area οf half circle = \((30 + 144 + 56.5) cm^2 = 230.5 cm^2\)

1.) Tο calculate the area οf a right-angled triangle, yοu can use the fοrmula:

Area = 1/2 x Base x Height

Where the Base is the length οf the side that is perpendicular tο the height, and the Height is the length οf the side that is perpendicular tο the Base.

In this case, the height is 12 cm and the base is 5 cm.

Therefοre, the area οf the triangle is:

Area = 1/2 x 5 cm x 12 cm

Area = 30 square cm

Sο, the area οf the right-angled triangle is 30 square centimetres.

2.) If bοth sides οf a rectangle are 12 cm, then it is a square.

Tο calculate the area οf a square, yοu can use the fοrmula:

Area = side x side

Substituting the given value οf side = 12 cm intο the fοrmula:

Area = 12 cm x 12 cm= 144 sq. cm

Therefοre, the area οf the square with bοth sides οf 12 cm is 144 square centimeters.

3.) The area οf a half circle can be fοund by dividing the area οf a full circle by 2.area οf a circle fdοrmula is:

Area = πr²

where (pi) is a mathematical cοnstant rοughly equal tο 3.14159 and r is the circle's radius.

Substituting the given value οf radius r = 6 cm intο the fοrmula:

Area οf a full circle = π(6 cm)²= 36π sq. cm

Area οf a half circle = 1/2 x 36π sq. cm= 18π sq. cm≈ 56.55 sq. cm (rοunded tο twο decimal places)

Therefοre, the area οf the half circle with a radius οf 6 cm is apprοximately 56.55 square centimeters.

By adding all the individuals areas οf the figure, we get 230.5 cm².

Given:

Usual cost of a bottle of sparkling water = $1.69 each

This week they are on sale for 4 for $5.

To find:

Did you pay more or less for the bottle this week?

Solution:

We have,

Usual cost of 1 bottle = $1.69

On sale, cost of 4 bottles = $5

On sale, cost of 1 bottles = \(\dfrac{\$5}{4}\)

                                         = $1.25

Since, $1.25 is less than $1.69, therefore the unit cost on sale is less than usual unit cost.

Hence, you pay less for the bottle this week.

Answer:

First of all, you are going to add

to each side. This will give you a new equation of

. The reason you add 5 is because you want to get rid of the -5x on the right. When you add 5 it changes to 0x. Anything times 0 equals 0. The next step is to divide both sides by 8. The reason you divide is to get x alone. When you divide 8x by 8, you get 1x. 1 times anything equals what the other thing is. For example, 1 times 4 is 4. This will give you your answer of

Answer:

between 10 and 12

Step-by-step explanation:

Given the measure of angles:

m∠B = 70°

m∠C = 60°

m∠A = 50°

Following this information, since the side lengths are directly proportional to the angle measure they see:

Angle B is the largest angle. Therefore, side AC is the longest side of the triangle since it is opposite of the largest angle.

Angle C is the smallest angle, so the side AB is the shortest side.

Therefore, side BC must be between 10 and 12 inches.

The friend has to save for 5 and 2/3 of a month to in order to make up the remaining 85 to get the 125 headphone.

An inequality that consists of two or more parts is called a compound inequality. Either "or" or "and" may be used in these components. A number between 5 and 10 could be used as x in an inequality, for instance, if it states that "x is larger than 5 and less than 10". Any time one of the two inequalities is true when the two inequalities are united by the word or, the compound inequality is solved. The two separate solutions have been combined to form the final answer. Inequalities that are separated by "and" or "or" form a compound inequality. The intersection of the inequality graphs is shown by the graph of a compound inequality with a "and."

Cost of the headphone 125.

What the friend have: 40.

What need to save: 125-40 = 85

Let x = amount to be saved per month

Months to save up the 85 is 15

The equation would be 15 x = 85

Therefore x = 85/15

Which is 5 2/3 months.

Answer: 25d

Step-by-step explanation:

3d - 2 = 1d

5(5) = 25

25(1d) = 25d

Answer:

75d-50

Step-by-step explanation:

First we can do the 5^2  (5*5=25)

25(3d-2)          Now use distributive property

(25*3d)  (25*-2)

75d-50    This is as far as we can go with simplifying  

a. The sample mean for sample 1 is 9.2, and the sample mean for sample 2 is 7.17.

b. The sample standard deviation for sample 1 is approximately 3.29, and the sample standard deviation for sample 2 is approximately 3.65.

c. The point estimate of the difference between the two population means is 2.03.

d. The 90% confidence interval estimate of the difference between the two population means is [-0.44, 4.50].

a. The sample mean for sample 1 is

(10 + 13 + 9 + 8 + 6) / 5 = 9.2

The sample mean for sample 2 is

(7 + 7 + 8 + 4 + 9 + 8) / 6 = 7.1667 ≈ 7.17

b. The sample standard deviation for sample 1 is:

√[((10-9.2)² + (13-9.2)² + (9-9.2)² + (8-9.2)² + (6-9.2)²) / (5-1)]

= √[10.8] ≈ 3.29

The sample standard deviation for sample 2 is

√[((7-7.17)² + (7-7.17)² + (8-7.17)² + (4-7.17)² + (9-7.17)² + (8-7.17)²) / (6-1)]

= √[13.33] ≈ 3.65

c. The point estimate of the difference between the two population means is:

9.2 - 7.17 = 2.03

d. To calculate the 90% confidence interval estimate of the difference between the two population means, we need to first calculate the standard error of the difference between the sample means:

s.e.(difference between sample means) = √[(s1²/n1) + (s2²/n2)]

= √[(3.29²/5) + (3.65²/6)]

= √[2.60]

≈ 1.61

Next, we can use the t-distribution with degrees of freedom equal to the smaller of n1-1 and n2-1 (in this case, 4) and a 90% confidence level to find the critical value, t*:

t* = 1.533 (from t-distribution table or calculator)

Finally, we can construct the confidence interval estimate:

9.2 - 7.17 ± (t* * s.e.(difference between sample means))

= 2.03 ± (1.533 * 1.61)

= 2.03 ± 2.47

= [ -0.44 , 4.50 ]
