what is the rate change of the table?

Answer:

y = 2x – 10

Step-by-step explanation:

ΔY divided by ΔX

= 5-7/0-4

= 2/1 = 2 (simplified)

plug in 2 into; 0=2(5)+b

= -10=b

so we have: y=2x-10

The best estimate of the percentage of apples picked at the orchard in October that is damaged will be 6%.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.

An apple orchard's workers pick 12,500 apples in the month of October.

A sample of 500 of these apples shows that 30 of them are damaged.

Then the best estimate of the percentage of apples picked at the orchard in October that is damaged will be

P = 30/500 x 100

P = 6%

Answer:

110

Step-by-step explanation:

The angle with given measure 110 and the angle that is represented with letter d are alternate angle and the measure of alternate angles is equal to each other

so the measure of d = 110

The solution of the equation √x+2 + 4 = 6 is x = 2 and it is not an extraneous solution

The solution of the equation can be found as follows;

√x+2 + 4 = 6

subtract 4 from both sides

√x+2 + 4 - 4 = 6 - 4

√x+2  = 2

square both sides

(√x+2)² = 2²

x + 2 = 4

x= 4 - 2

x = 2

Therefore the solution is x = 2 and it is not a extraneous solution.

Answer:

Step-by-step explanation:

Answer:

The formula to get the circumference of a circle is [tex]C=2*\pi * r[/tex] but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this [tex]C=d*\pi[/tex].

We can then input the value and we get that [tex]C=5*\pi[/tex] which then just narrows down to [tex]C=15.708[/tex].

Bc I know how to do math

volume: volume of cone is 1/3πr^2h

radius is 2

height is 6

plug into equation: 1/3π(2)^2*6=about 2.55 or 8π

surface area: surface area of cone is πrs+πr^2 where s is slant height.

to find slant height use pythagorean theorem: √(2^2+6^2)=√40

radius: 2

height:6

slant height: √40

plug into equation: π(2)(√40)+π(2^2)=about 52.30 or 4√10π+4π

  j(x) = x² +4x -1 = (x +4)x -1

  j(-2) = (-2 +4)(-2) -1 = 2(-2) -1 = -5

__

  f(5) +j(-2) = -3 +(-5) = -8

Step-by-step explanation:

your a. is wrong.

so, we need to do both.

a.

you did not really read carefully. DE = 4x and not 4.

DE = 4x does not mean x = 4. absolutely not.

so, you cannot just use x=4 in the first triangle.

but you are right, AB and DE correlate between the 2 congruent triangles.

therefore

3x + 6 = 4x

6 = x

so, AB = 3x + 6 = 3×6 + 6 = 18 + 6 = 24 ft

b.

congruent means that the sides and the angles are the same between the 2 triangles.

so,

6y + 12 = 8y + 2

12 = 2y + 2

10 = 2y

y = 5

so, the angle EDF is

8y + 2 = 8×5 + 2 = 40 + 2 = 42°

Using the normal distribution, it is found that a weight of 3125 grams would given a newborn a z-score of −0.75.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

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

Researching the problem on the internet, it is found that the mean and the standard deviation for the weight of newborns is given as follows:

[tex]\mu = 3500, \sigma = 500[/tex]

Hence, the weight associated with Z = -0.75 is given by X:

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

[tex]-0.75 = \frac{X - 3500}{500}[/tex]

X - 3500 = -0.75(500)

X = 3125.

The parameters are:

In this problem:

The probability that is lands tails up at least nine times is given by:

[tex]P(X \geq 9) = P(X = 9) + P(X = 10)[/tex]

In which:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 9) = C_{10,9}.(0.5)^{9}.(0.5)^{1} = 0.0098[/tex]

[tex]P(X = 10) = C_{10,10}.(0.5)^{10}.(0.5)^{0} = 0.001[/tex]

Hence:

[tex]P(X \geq 9) = P(X = 9) + P(X = 10) = 0.0098 + 0.001 = 0.0108[/tex]

0.0108 = 1.08% probability of the coin landing tails up at least nine times.

The volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

We know the surface area of the sphere is given by:

SA = 4πr²

1465 = 4πr²

r = 10.79 cm

Volume of the sphere = 4πr³/3

V = 4π(10.79)³/3

V = 5262.03 cubic cm

Volume of five volleyballs = 5×5262.03 = 26310.15 cubic cm

Thus, the volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.

The sum of digits of the products is given by S = 176

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The number 22 multiplied by a 22-digit number that contains only "2"s would result in a number that consists of a string of "4"s.

This is because 2 multiplied by 2 results in 4. Since all the digits in the 22-digit number are "2"s, each digit would multiply by 2 and result in "4".

Therefore, the product of 22 multiplied by a 22-digit number that contains only "2"s would be a 44-digit number consisting of "4"s.

The sum of the digits of a 44-digit number consisting of only "4"s can be calculated by multiplying the digit "4" by the total number of digits, which in this case is 44.

Sum of digits = 4 × 44 = 176

Hence , the sum of the digits of the product would be 176
