Answer:

(-5, 0)

Step-by-step explanation:

f(x) = (x - 1)(x2 + x - 20) = 0

x - 1 = 0

x = 1

x^2 + x - 20 = (x + 5)(x - 4)

x + 5 = 0; x - 4 = 0

x = -5; x = 4

Answer: (-5, 0)

Answer:  1.2

Step-by-step explanation:

Let X denotes the grades on a  language midterm at Oak Academy.

As per given ,

X follows normal distribution ( because it has symmetric graph)

[tex]\mu=67,\ \ \ \ \sigma= 2.5[/tex]

Formula for z : [tex]z=\dfrac{X-\mu}{\sigma}[/tex]

For X = 70, we have

[tex]z=\dfrac{70-67}{2.5}=\dfrac{3}{2.5}=1.2[/tex]

Hence, the z-score for Ishaan's exam grade = 1.2

z-scores are the corresponding standard normal variate's values for normal variates' values. The z-score for Ishaan's grade is 1.2

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] )

then it can be converted to standard normal distribution as

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

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

[tex]P(Z \leq z) = P(Z < z) )[/tex]

Also, know that if we look for Z = z in z tables, the p-value we get is

[tex]P(Z \leq z) = \rm p \: value[/tex]

For the given case, if we suppose the random variable X's values as scores of the grades on given language midterm at Oak Academy, then, as it is symmetric around value 67, with σ = 2.5, thus,

[tex]X = N(\mu = 67, \sigma = 2.5)[/tex]

Its given that Ishaan scored X = 70

The standard normal variate conversion of X is given by:

[tex]Z = \dfrac{X- \mu}{\sigma} = \dfrac{X - 67}{2.5}[/tex]

Thus, z-scores for Ishaan's score is: [tex]Z = \dfrac{70 - 67}{2.5} = \dfrac{3}{2.5} = 1.2[/tex]

Answer:

3 + 7x = 7x + 3

Step-by-step explanation:

Simplifying

7x + 3 = 7x + 3

Answer:

Angle A = 45 degrees

Step-by-step explanation:

7x+3 + 7x+3 +90 = 180

14x + 96 = 180

14x = 84

x = 6

Angle A = 7x+3. --> 7(6) + 3 --> 45

Angle A = 45 degrees

Answer:

A. [tex] \overline{OC} \perp \overline{AB} [/tex]

Step-by-step explanation:

According to tangent theorem, a tangent is formed when the radius of a circle is perpendicular to the line, meeting at a point around the circle, such that the tangent line would be perpendicular to the radius of the circle with a center.

Given that [tex] \overline{AB} [/tex] is a tangent of the circle O, at a point C, and [tex] \overline{OC} [/tex] is a radius, therefore, it follows that:

[tex] \overline{OC} \perp \overline{AB} [/tex].

This means the radius of the circle is perpendicular to the tangent formed at point C.

Answer: 1, 7 is he answer I just took the quiz and got it correct.

Step-by-step explanation:

Alright, it went 1 to the right and down 2 times.

So for point B, you calculate the opposite.

Point B goes 1 left while going up by 2.

(9 - 1, 3 + 2) = (8, 5)

Pre-image point A is (8, 5)

The preimage of point A before a translation right 1 unit and down 2 units

is (8, 5).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, The image point of A after a translation right 1 unit and down 2 units is point B (9, 3) so we go exact opposite 1 unit left and 2 units up which is

(- 1, 2).

∴ The pre-image point A is (8, 5).

Answer:

[tex]n = 4752 \ gallons[/tex]

Step-by-step explanation:

Given

Delivery: 396 dozens gallons in a day

Required

Determine the number of gallons in a day

From the question above, we understand that:

[tex]n = 396\ dozens\ gallon[/tex]

From unit conversion:

[tex]1\ dozen = 12[/tex]

So:

[tex]n = 396\ dozens\ gallon[/tex] becomes

[tex]n = 396 * 12 \ gallon[/tex]

[tex]n = 4752 \ gallons[/tex]

Hence, 4752 gallons of milk is delivered daily

Answer:

The elevation of the rest stop is 37.5 feet above sea level.

Step-by-step explanation:

Given that the elevation at the top of the hill is 127 feet above sea level and The valley floor is 52 feet below sea level.

So, the total length from the top of the hill to the valley floor

[tex]l= 127+52 = 179[/tex] feet

So, length of halfway [tex]= l/2=179/2=89.5[/tex] feet ...(i)

Assuming that the stop for rest, the halfway between the top of the hill and the valley floor, is at x feet above sea level.

So, the length between the stop position and the valley floor [tex]= 52 +x[/tex] feet.

As the stop position is at half-way, so by using equation (i), we have,

[tex]52 + x = 89.5 \\\\\Rightarrow x =89.5-52 \\\\[/tex]

[tex]\Rightarrow x=37.5[/tex] feet

Hence, the elevation of the rest stop is 37.5 feet above sea level.
