Answer:

4(4x + 7)

Step-by-step explanation:

To answer this question you need to understand what GCF is

GCF is Greatest Common Factor

GCF is the highest number that divides exactly into two or more numbers.

The expression is 16x + 28

The highest number that can divide 16 and 28 is 4

Dividing 16x + 28 gives => 16x/4 + 28/4 => 4x + 7

So the factored expression is

4(4x + 7)

Answer:

35

Step-by-step explanation:

sum the parts of the ratio, 4 + 5 = 9 parts

divide 63 by 9 to find the value of 1 part of the ratio

63 ÷ 9 = 7 , then

4 parts = 4 × 7 = 28

5 parts = 5 × 7 = 35 ← larger share

2.69%, is the required maximum percent error among the predictions.

Given,

The predicted winning time in 200 meter sprint shows in the dot plot

The winner finished the race in 22.3 seconds

We have to find the greatest percent error among the predictions;

Here,

The actual time to complete is 22.3 seconds.

22.9 seconds is the prediction that is the most off.

The difference is, 22.9 - 22.3 = 0.6 seconds

To obtain a prediction, divide this by the actual time value.

= 0.6/22.3 = 0.0269 = 2.69

Therefore, 2.69%, is the required maximum percent error among the predictions.

A) distribution of x and its parameter(s) is (λ^x e^-λ ) / x!  

B) standard deviation of x is 1

C) probability that x is (inclusively) within one standard deviation of the mean of x is 0.7358

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

A) The poisson distribution with mean is followed by X = λ = 1

Therefore, ≈ (λ = 1)

Distribution of X is:

(λ^x e^-λ ) / x!   ,    x = 0, 1, 2, 3 ......

B) Standard Deviation of X is :

σx = √x = 1

C) Probability of X = P (-1 ≤ x ≤ 1)

P(x = 0) + P(x = 1)

= (1⁰ e⁻¹) / 0! + 1¹ e-¹ / 1!

= 2e⁻¹

The dimensions of the left triangle are equal to the right triangle's dimensions times 1/3.

Given,

The right triangle on the right is a scaled copy of the right triangle on the left.

The measure of first triangle = 3,4

The measure of second triangle = 2, 3/2

We have to find the scale factor

The figure indicates that the right triangle on the left would be three times larger than the right triangle on the right. In this case, the right triangle's dimension is one third of the left triangle's dimension.

The left one is three times bigger than the right one. In other words, the dimensions of the left triangle are equal to the right triangle's dimensions times 1/3.

Step-by-step explanation:

100% = $250

1% = 100%/100 = 250/100 = $2.50

the price decreased by

250 - 180 = $70

how many % are $70 ?

as many as how many times 1% ($2.50) fits into $70 :

70 / 2.50 = 28%

it changed (decreased) by 28%.

The weight of Brad is 70 lb and the weight of Sean is 150 lb now.

According to the question,

We have the following information:

Sean weighs 10 lb more than twice Brad’s weight. If Brad gains 10 lb, together they will weigh 230 lb.

Now, let's take Brad's weight to be x lb.

So, we have:

Sean's weight = (10+2x) lb

Now, when Brad gains 10 lb, we have the following expression:

(x+10)+(10+2x) = 230

3x+20 = 230

3x = 230-20

3x = 210

x= 210/3

x = 70 lb

Now, Sean's weight = (10+2x) lb

Putting the value of x:

Sean's weight = 10+2*70

Sean's weight = 10+140

Sean's weight = 150 lb

Hence, the weight of Brad is 70 lb and the weight of Sean is 150 lb now.

The equation of the line that passes through point (-5,3) and perpendicular to y=5x-3 is y = -(1/5)x + 2.

The point-slope formula is expressed as

y - y₁ = m( x - x₁ )

Given the data in the question;

First, determine the slope of the initial line using the slope intercept-form. y = mx + b

y = 5x - 3 compared with the slope intercept form,

Slope m = 5

Now, for the equation of line perpendicular to the initial line, its slope must be a negative reciprocal of the initial slope.

Hence, slope of the perpendicular line is;

Slope m = -1/5

Next, find the equation of the perpendicular line, by using the point slope formula.

y - y₁ = m( x - x₁ )

Plug in the slope m ( -1/5 ) and point (-5,3).

y - y₁ = m( x - x₁ )

y - 3 = -1/5( x - (-5) )

y - 3 = -1/5( x + 5 )

y - 3 = -1/5(x) -5/5

y - 3 = -1/5(x) - 1

y = -1/5(x) - 1 + 3

y = -(1/5)x + 2

Therefore, the equation of the perpendicular line is y = -(1/5)x + 2.

The Pythagorean Theorem states that the squares on the hypotenuse of a right triangle, or, in standard algebraic notation, a² + b² = c².

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a² + b² = c².

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

First use the Pythagorean theorem. a² + b² = c²

then take the first derivative of it to get

2a(a') + 2b(b') = 2c(c')

Now figure out how far the train is after 4 seconds

6(4)=24
