Answer:

-2

Step-by-step explanation:

We start off by subtracting 4 on both sides giving us:

sqrt(x+3) = 5-4 = 1

So,

sqrt(x+3) = 1, and squaring both sides we get x+3 = 1

Therefore,

x = -2

Answer:

x = -2 & -4

Step-by-step explanation:

√(x + 3) + 4 = 5

√(x + 3) = 5 - 4

√(x + 3) = 1

[√(x + 3)]² = (1)²

x² + 9 + 6x = 1

x² + 9 - 1 + 6x = 0

x² + 8 + 6x = 0

x² + 6x + 8 = 0

x² + (4x + 2x) + 8 = 0

x² + 4x + 2x + 8 = 0

x(x + 4) + 2(x + 4) = 0

(x + 4)(x + 2) = 0

x = -2 & -4

Hence,

Value of x is -2 & -4

Step-by-step explanation:

Julian bought a total of 8 packs of beef franks, each containing 15 beef franks. So the total number of beef franks is:

8 packs × 15 beef franks/pack = 120 beef franks

Julian, Angel, Pedro, and Miguel together cooked all 120 beef franks. Let's add up the fractions they cooked:

5/12 + 3/20 + 1/6 + Miguel's fraction = (25 + 9 + 10M + 60M) / (60*20)

= (34 + 70M) / 120

We know that this fraction must equal 1 (since they cooked all the beef franks), so we can set up an equation:

(34 + 70M) / 120 = 1

Solving for M, we get:

34 + 70M = 120

70M = 86

M = 43/35

Therefore, Miguel cooked 43/35 of the beef franks. This fraction can be simplified:

43/35 = 1 + 8/35

So Miguel cooked 1 and 8/35 of the beef franks.

1. The scale factor here in the dilation is 4/3.

2. Yes, dilation occurred on the coordinate plane below. The scale factor for the dilation is -4/3.

During the process of dilatation, an object must be reduced in size or changed. It is a transformation that uses the given scale factor to shrink or expand the objects. The image is the new figure that forms as a result of dilatation, whereas the pre-image is the original figure. There are two kinds of dilation:

A rise in an object's size is referred to as expansion.

Contraction is the term used for a reduction in size.

Here in the question,

The coordinates of the point B change from (-3,6) to (-4,8).

The scale factor here is -4/-3=4 or 8/6=4/3.

Now, when the dilation happens below the plane, the coordinates will be (x,-y)

So, the dilation factor will be -4/3.

Heather's account balance will be approximately $4,179.60 after 9 years if the interest is compounded 4 times each year.

Interest is the cost of borrowing money or the compensation received for lending money. It is usually expressed as a percentage of the amount borrowed or lent, and it is calculated based on the principal (the initial amount borrowed or lent), the interest rate, and the time period for which the money is borrowed or lent.

Compounding refers to the process of earning interest on both the principal amount and the accumulated interest earned over time. In other words, it is the interest earned on interest.When interest is compounded, the interest earned in each compounding period is added to the principal amount, and the new total becomes the basis for calculating interest in the next period.

In the given question,

We can use the formula for compound interest to find Heather's account balance after 9 years:

A = P * (1 + r/n)^(n*t)

where A is the account balance, P is the principal (initial investment), r is the interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

Plugging in the given values, we get:

A = 2975 * (1 + 0.035/4)⁴ˣ⁹

Simplifying this expression, we get:

A = 2975 * (1.00875)³⁶

Using a calculator or a computer, we can evaluate this expression to get:

A ≈ $4,179.60

Therefore, Heather's account balance will be approximately $4,179.60 after 9 years if the interest is compounded 4 times each year.

Answer:

400

Step-by-step explanation:

it says average which probably means 400

33.36% of these homes have a value greater than $83,500.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

\(z=\frac{x-\mu}{\sigma} \\\\where\ x \ is\ raw\ score,\mu=mean,\sigma=standard\ deviation\)

Given that μ = $82000, σ = $5000.

For x > 83500:

\(z=\frac{83500-82000}{5000} =0.43\)

From the normal distribution table, P(x > 83500) = P(z > 0.43) = 1 - P(z < 0.43) = 1 - 0.6664 = 33.36%

A. Mean

Step-by-step explanation:

Mean can also be described as the average of a data set.

The calculated average of a data set is the sum of all data values divided by the number of data values we have in a data set. This is the same as the mean.

For example, let's say you bought 5 t-shirts. The cost of the 5 t-shirts can be regarded as a data set, which are: $10, $10, $11, $12, and $15.

The average cost of t-shirt bought by you can be calculated as:

Average = Mean = (10 + 10 + 11 + 12 + 15)/5

= 58/5

= 11.6

The average cost of t-shirt you bought, which is also the mean cost of t-shirt is $11.6

Step-by-step explanation:

The length of the longer wire is 82 feet.

Let's denote the length of the longer wire as L. According to the given information, the shorter wire is attached to the ground 16 feet from the base of the pole, and the longer wire is attached to the ground 32 feet from the base of the pole.

We can form two similar right triangles using the wires. The height of each triangle is the height of the pole, and the base of each triangle is the distance from the base of the pole to where the wire is attached to the ground.

In the first triangle, the shorter wire creates an angle with the ground. Let's denote this angle as θ. Since we are given the cosine of this angle, we can use the cosine function to find the height of the pole in terms of θ and the base of the triangle:

cos(θ) = adjacent/hypotenuse = 16/L

Given that cos(θ) = 8/41, we can substitute this value into the equation:

8/41 = 16/L

To solve for L, we can cross-multiply and solve for L:

8L = 41 * 16

L = (41 * 16)/8

L = 82

Therefore, the length of the longer wire is 82 feet.

In summary, the length of the longer wire is 82 feet, as determined by using the cosine of the angle formed by the shorter wire and the ground, and considering the similarity of the triangles formed by the wires and the pole.

Answer:

number 2.) 1,500g

Step-by-step explanation:

i just know..

Answer:

The correct options are:

(1) A

(2) C

Step-by-step explanation:

The complete question is:

For a sample of 119 transformers built for heavy​ industry, the mean and standard deviation of the number of sags per weeks were 338 and 22​, ​respectively; also, the mean and standard deviation of the number of swells per week were 174 and 15​, respectively. Consider a transformer that has sags 375 and 120 swells in a week.

(1)

A z-score less than -2 or more than 2 are considered as unusual.

Compute the z-score for 314 sags per week​ as follows:

\(z=\frac{x-\mu}{\sigma}\)

   \(=\frac{314-338}{22}\\\\=-1.091\)

The z-score for 314 sags per week is -1.091.

This value is more than -2.

Thus, the correct option is:

A. No. The Z-score is -1.091 meaning that the number of sags is not unusual and is not an outlier.

(2)

Compute the z-score for 243 swells per week as follows:

\(z=\frac{x-\mu}{\sigma}\)

   \(=\frac{243-174}{15}\\\\=4.6\)

The z-score for 243 swells per week is 4.6.

This value is more than 2.

Thus, the correct option is:

C. Yes. The z-score is 4.6 meaning that this is an outlier and almost every other transformer has fewer swells.

1). The decision regarding the consideration of 314 sags every week unusually would be:

a). No. The Z-score is meaning that the number of sags is not unusual and is not an outlier.

2). The decision regarding the consideration of 243 swells every week every week unusually would be:

c). Yes. The z-score is meaning that this is an outlier and almost every other transformer has fewer swells.

a). Given that

No. of transformers = 119

Mean = 338

Standard Deviation for the week = 22

Now,

z-score for sags = (No. of sags - Mean)/Standard Deviation

\(= (314 - 338)/22\\= -1.091\)

Since it is greater than -2, option A is the correct answer.

b). Given that

No. of swells = 243

Mean for swells = 174

Standard Deviation = 15

Now,

z-score for sags = (No. of sags - Mean)/Standard Deviation

\(= (243 - 174)/15\\= 4.6\)

Since it is greater than 2, it exemplifies an outlier. Thus, option C is the correct answer.

Thus, options A and C are the correct answers.

Answer:

It is a 9/10 chance of having at least one boy. The probability is also high enough for the couple to be very confident in having at least one boy in 9 children.

Step-by-step explanation:

I listed all of the possible combinations below

GGGGGGGGG           BGGGGGGGG

BBGGGGGGG           BBBGGGGGG

BBBBGGGGG           BBBBBGGGG

BBBBBBGGG            BBBBBBBGG

BBBBBBBBG             BBBBBBBBB

Total number of combinations with at least one boy is 9/10

This is a very high percentage, which means the couple is very likely to have at least one boy.

To solve this problem, we can use the formula for probability:

P(event) = number of favorable outcomes / total number of outcomes

First, let's find the total number of outcomes. We are selecting 4 balls from 11 without replacement, so the total number of outcomes is:

11C4 = (11!)/(4!(11-4)!) = 330

where nCr is the number of combinations of n things taken r at a time.

Now let's find the number of favorable outcomes for each part of the problem.

Part 1: Exactly two white balls and two red balls

To find the number of favorable outcomes for this part, we need to select 2 white balls out of 6 and 2 red balls out of 5. The number of ways to do this is:

6C2 * 5C2 = (6!)/(2!(6-2)!) * (5!)/(2!(5-2)!) = 15 * 10 = 150

So the probability of selecting exactly two white balls and two red balls is:

P(2W2R) = 150/330 = 0.45 (rounded to two decimal places)

Part 2: At least two white balls

To find the number of favorable outcomes for this part, we need to consider two cases: selecting 2 white balls and 2 red balls, or selecting 3 white balls and 1 red ball.

The number of ways to select 2 white balls and 2 red balls is the same as the number of favorable outcomes for Part 1, which is 150.

To find the number of ways to select 3 white balls and 1 red ball, we need to select 3 white balls out of 6 and 1 red ball out of 5. The number of ways to do this is:

6C3 * 5C1 = (6!)/(3!(6-3)!) * (5!)/(1!(5-1)!) = 20 * 5 = 100

So the total number of favorable outcomes for selecting at least two white balls is:

150 + 100 = 250

And the probability of selecting at least two white balls is:

P(at least 2W) = 250/330 = 0.76 (rounded to two decimal places)

Sales tax is a percentage of the sale price of an item that is then added on to the total price of the item.

let's say you are buying an item priced at $10.00 and the sales tax rate is 6%. Sales tax rates can vary from state to state and even within counties or cities.
