Answer:

3

Step-by-step explanation:

(x + 7)(x - 4)

= x · x + x · (-4) + 7 · x + 7 · (-4)

= x² - 4x + 7x - 28

= x² + 3x - 28

Hence, g = 3.

Answer:

A score of 314 is needed to be in the top 25% of students who take this exam.

Step-by-step explanation:

We are given that one of the tests provided by the NAEP assesses the reading skills of twelfth-grade students. In recent years, the national mean score was 289 and the standard deviation was 37.

Let X = scores of the tests provided by the NAEP

The z-score probability distribution for the normal distribution is given by;

                           Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = national mean score = 289

           [tex]\sigma[/tex] = standard deviation = 37

Now, we have to find how high a score is needed to be in the top 25% of students who take this exam, that means;

            P(X > x) = 0.25     {where x is the required score}

            P( [tex]\frac{X-\mu}{\sigma}[/tex] > [tex]\frac{x-289}{37}[/tex] ) = 0.25

            P(Z > [tex]\frac{x-289}{37}[/tex] ) = 0.25

In the z table, the critial value of z that represents the top 25% of the area is given as 0.6745, that is;

                        [tex]\frac{x-289}{37}=0.6745[/tex]

                        [tex]{x-289}=0.6745\times 37[/tex]

                        x = 289 + 24.96 = 313.96 ≈ 314

Hence, a score of 314 is needed to be in the top 25% of students who take this exam.

Answer:

23.33%

Step-by-step explanation:

The computation of the percentage of days in a month for running out of cash is shown below:

Percentage of running out of Cash is

= (Relevant Occurrence  of an event ÷  Total number of events) × 100%

where,

The Relevant occurrence of an event is 7 (105,94,101,98,94,96,92)

And, the total number of events is 30 i.e. 30 days

So, the percentage is

= 7 ÷ 30 × 100

= 23.33%

Answer:

infinite solutions

Step-by-step explanation:

Given

4(x - 3) = 2x + 2x - 6 - 6 ← distribute left side and simplify

4x - 12 = 4x - 12

Since both sides are equal then the equation has an infinite number of solutions.

Answer:

Reuben made 76.5 servings of Peach ice cream

Step-by-step explanation:

Total gallons of peach ice cream made = 3.4 gallons

Number of servings per gallon = 22.5

This means that:

1 gallon = 22.5 servings

∴ 3.4 gallons = 22.5 × 3.4 = 76.5 servings

Therefore, Reuben made 76.5 servings of Peach ice cream

Step-by-step explanation:

∠ABD ≅ ∠BDE..... (given).... (1)

m∠ABD + m∠CBD = 180°... (straight line ∠'s)... (2)

From equations (1) & (2)

m∠BDE + m∠CBD = 180°....(3)

m∠BDE + m∠CDB = 180°... (straight line ∠'s)... (4)

From equations (3) & (4)

m∠BDE + m∠CBD = m∠BDE + m∠CDB

Answer:

1050 times larger

Step-by-step explanation:

simply multiply two expression and divide the first by the the second

(8×105)/(8×10^-1)= 1050

Step-by-step explanation:

Yes. The cube root of a negative number will be negative.

For example, (-2)^3 = -8. The cube root of -8 is -2.

Answer:

Yes, it would be negative

Step-by-step explanation:

Yes, the cube root of a negative number can be found without using imaginary numbers to represent it.

The cube of a number is that number multiplied by itself 3 times so:

a^3 = a*a*a

if "a" is negative then the cube of "a" will be negative. Hence the cube root of a negative number will be negative.

Answer:

(- 6, 0 ) , (2, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0, that is

x² + 4x - 12 = 0 ← in standard form

(x + 6)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 2 = 0 ⇒ x = 2

Thus the x- intercepts are (- 6, 0 ), (2, 0 )

Answer:

AngleAFB

Step-by-step explanation:

We know that vertical angles are angles that opposite each other when two lines intersect. They share a common point or vertex.

In the question, the angle opposite to angle EFD is angle AFB. This is because they share a common vertex.

Since they share a common vertex and are opposite to each other, angle AFB is the angle vertical to angle EFD.

So, the angle vertical to angle EFD is angle AFB.

The given information are;

The coordinate of the point A on a (horizontal) number line = 0

The length of AR =

The coordinate of the midpoint of AR are given as follows;

Coordinate of the midpoint = Coordinate of A ± (Length of AR)/2 which gives;

The possible coordinates of the midpoint as 0 + 6/2 = 3 or 0 - 6/2 = -3

The possible coordinates of the midpoint are 3 and -3

[tex]\boxed{\bold{\huge{\boxed{5}}}}[/tex]

Step-by-step explanation:

625 when divided by 5 gives 125 which is a perfect cube.

=> [tex]\sf \frac{625 }{5 } = 125[/tex]

[tex]\rule[225]{225}{2}[/tex]

[tex]\sf \ \sqrt[3]{125} = 5[/tex]

So, 5 needs to be divided by 625 to make the quotient a perfect cube!
