Answer:

a= 2/5 =0.4

Step-by-step explanation:

19a−6=4a

Subtract 4a from both sides.

19a−6−4a=0

Combine 19a and −4a to get 15a.

15a−6=0

Add 6 to both sides. Anything plus zero gives itself.

15a=6

Divide both sides by 15.

a= 6/15

​

Reduce the fraction  6/15 to lowest terms by extracting and canceling out 3.

a=2/5

Answer:

p = 19

x = 64

y = 100

Step-by-step explanation:

114 = 6p

Divide by 6 into both sides

p = 19

x/4 = 16

Times 4 into both sides

x = 64

75 = y - 25

Add 25 to both sides

y = 100

Answer:

48

Step-by-step explanation:

Let T be the number of texts sent on each plan.

The cost of Plan A can be represented as $9.25 + $0.06T.

The cost of Plan B can be represented as $2.50 + $0.20T.

We want to find the number of texts T at which the two plans cost the same amount. Therefore, we can set the two equations equal to each other and solve for T:

$9.25 + $0.06T = $2.50 + $0.20T

Subtracting $2.50 from both sides, we get:

$6.75 + $0.06T = $0.20T

Subtracting $0.06T from both sides, we get:

$6.75 = $0.14T

Dividing both sides by $0.14, we get:

T = 48.21

Therefore, the number of texts at which the two plans cost the same amount is approximately 48 texts. This means that if you send fewer than 48 texts per month, Plan A will be cheaper, and if you send more than 48 texts per month, Plan B will be cheaper.

Answer: Y=-2x-5

Step-by-step explanation:

Points: (-4, 3) & (-3, 1)

To find the slope, we use m= (y₂-y₁)/(x₂-x₁)

With these points, m= (1-3)/(-3--4)

This gives us m= -2/1, or -2

Slope-intercept form is y=mx+b

We can plug in the slope now, so y=-2x+b

B is the y-intercept, which is -5, in this case

This gives us y=-2x-5

The term that represents the situation shown in the graphic below is B. a reflection

A glide reflection or transflection is a symmetry operation in two-dimensional geometry that combines a reflection over a line with a translation along that line into a single operation.

An exchange of points from one side of a line with points on the other side of the mirror at the same distance from the mirror occurs when a mirror line is fixed in the plane. There is a mirror line in every reflection. A mirror reflection is followed by a translation that is parallel to the mirror to create a glide reflection.

Here, the shape is mirrored in the reflection. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

In conclusion, based on the information given, it should be noted that the correct option is B.

What is largest ?

There is a big number—a googolplex—that exists. It consists of 1 and 10100 zeros (googol). A googolduplex, which is an even larger number, is also present. It is 1 and over a googol zeros after that.

Let 'n' be any number, odd or even.

2n will always be even number. This is because, 2n has 2 as common factor. So, 2n is always even.

Eg: 2= 2×1, n=1 ; 4=2×2, n=2 etc

Numbers are even, consecutive.

Consecutive even numbers are 2n-2, 2n, 2n+2,

Eg : For consecutive even numbers, put n=2

2n-2=4-2=2

2n=4

2n+2 =4+2=6,

we get 2,4,6 which are consecutive even nos.

So, numbers are 2n-2, 2n and 2n+2

Their sum= 2n+2+2n+2n-2=6n

Sum=54

6n=54

n=54/6=9

So, n=9

Consecutive numbers are

2n-2= (2×9)-2=16

List all of the integer values that could take that would satisfy the inequality shown on the number line below. ​

Answer:

Step-by-step explanation:

If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:

[tex]\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]

Given:

Therefore, if the heights of men are normally distributed:

[tex]\boxed{X \sim\text{N} \left(69.0, 2.8^2 \right)}[/tex]

where X is height in inches.

Given:

Find the probability that the heights of men is between 64 and 78 inches by calculating P(64 ≤ X ≤ 78).

Calculator input for "normal cumulative distribution function (cdf)":

⇒ P(64 ≤ X ≤ 78) = 0.9622733869...

To calculate how many men who want to enlist in the U.S. Marine Corps would not expect to meet the height requirements from a group of 500, multiply 500 by 1 less than the probability found above:

⇒ 500 × [1 - P(64 ≤ X ≤ 78)]

⇒ 500 × [1 - 0.9622733869...]

⇒ 500 × 0.03772661307...

⇒ 18.86330654...

Therefore, we would expect for 19 men to not meet the height requirements.

Let the larger angle be x.

Smaller angle = x - 8

As both angles are supplementary,

x + (x - 8) = 180°

2x - 8 = 180°

2x = 188°

x = 94°

Therefore, larger angle = 94°

Smaller angle = 94° - 8° = 86°

Answer:

The number of downloads of the standard version is 230.

Step-by-step explanation:

Let x be the number of downloads of the standard version.

The number of downloads of the high-quality version is 4x.

The total size downloaded for the standard version is 2.8x MB.

The total size downloaded for the high-quality version is 4.3(4x) = 17.2x MB.

The total size downloaded for both versions is 2.8x + 17.2x = 4600 MB.

Combining like terms, we have 20x = 4600 MB.

Dividing both sides by 20, we have x = 230 downloads of the standard version

the number of fih at 9:00 A.M. (794), which yields 209 fih, the number of fih left at 5:00 P.M. is 585 fih

Subtract the number of fih at 9:00 A.M. (794) from the number of fih left at 5:00 P.M. (209).

794 - 209 = 585

Therefore, the dolphin ate 585 fih.

To estimate how many fih the dolphin ate, we must first subtract the number of fih at 9:00 A.M. (794) from the number of fih left at 5:00 P.M. (209). This gives us 585 fih, which is the estimated number of fih that the dolphin ate. This calculation can be verified by subtracting the number of fih the dolphin ate (585) from the number of fih at 9:00 A.M. (794), which yields 209 fih, the number of fih left at 5:00 P.M.

True. the interpretation of the slope is different in a multiple linear regression model as compared to a simple linear regression model.

The slope and intercept of a line reveal the steepness of the line and the location in which it intersects an axis. The slope and intercept of the logistic relationship of the two variables can be utilized to get the average change rate. The ratio of a change in the variable y to the rise in the x component is known as the the line's slope.

The area of the square is bigger than the Area of the rectangle.

Suppose the sum of all the sides in a square is this: 4 x A and the same is true of a rectangle, too.

Then, first, the area of the square is A^2.

And next, assuming that we have this: 0 < X < A and that one side in the rectangle is this: (A - X)

we can say that the side next to (A - X) is this: (A + X) because the sum of all the four sides in the rectangle has to be this: (4 x A), which equals the sum of all the sides in the square.

So now, the area of the square is this: A^2, whereas the area of the rectangle is this: (A^2 - X^2), which equals this: (A + X)(A - X).

You know thus now, which of the two areas is bigger, and it’s the area of the square. And the difference between the two areas is this: X^2.

The study revealed that 87% of movie customers spend an average of $6.39 or less on concessions.

To calculate the spending amount that corresponds to the top 87th percentile, we must first calculate the z-score. To do this, subtract the mean of $4.11 from the desired percentile of $6.39, resulting in a difference of $2.28. Next, divide the difference of $2.28 by the standard deviation of $1.37, resulting in a z-score of 1.67. Finally, use a z-score table to find the corresponding percentile of 87%. This means that 87% of movie customers spend an average of $6.39 or less on concessions.

As per the impact of reducing the tolerable rate of deviation from 7% to 5% on the sample size is 93.

The term deviation is defined as a measure that is used to find the difference between the observed value and the expected value of a variable.

Here we have given that the audit team is planning to examine a sample of control policies and procedures. assume that, based on the intended degree of reliance on internal control, the audit team wishes to control the risk of overreliance to 5%.

And we need to find sample size.

While we looking into the given question, we know that the tolerable rate of deviation from 7% to 5% on the sample size.

Let us consider that 100 be the sample size, then the reduction in 7% to 5%, tell that there is an 2% decrement in the sample size.

Therefore, it can be calculated as,

=> 100 x 2/100

=> 2

Here we already know that the risk of overreliance to 5%.

Then the total value is
