The parallelogram shown below has an area of 60 units^2

Answer:

(-3,-1) -> (3,1)

Step-by-step explanation:

Reflection over the y-axis:

When we reflect a point (x,y) over the y-axis, it's y-coordinate is kept, while the x-coordinate changes signal. So

(3,-1) -> (-3,-1)

Clockwise rotation of 180º

Both coordinates of the point change signals. So

(-3,-1) -> (3,1)

Answer:

Imao

Step-by-step explanation:

Given:

Selling price of each CD = $5.00

Cost price of each CD = $1.25

Number of CDs ordered = 300

Profit must be at least $500.

To find:

The number of CDs needs to sell.

Solution:

Let n be the number of CDs needs to sell.

Selling price of each CD = $5.00

Selling price of x CDs = $5n

Cost price of each CD = $1.25

Cost price of 300 CDs = 300×$1.25

                                      = $375

We know that,

[tex]Profit=S.P.-C.P.[/tex]

[tex]Profit=5n-375[/tex]

Profit must be at least $500. it means profit must be greater than or equal to $500.

[tex]5n-375\geq 500[/tex]

[tex]5n\geq 500+375[/tex]

[tex]n\geq \dfrac{875}{5}[/tex]

[tex]n\geq 175[/tex]

All options are incorrect. The required inequality is n is greater than or equal to 175.

Answer:

Roots are also called x-intercepts or zeros. A quadratic function is graphically represented by a parabola with vertex located at the origin, below the x-axis, or above the x-axis. Therefore, a quadratic function may have one, two, or zero roots. are given by the quadratic formula.

Answer:

a.) f(x) = [tex]\frac{1}{30}[/tex] where 90 < x < 120

b.) [tex]\frac{2}{3}[/tex]

c.)  [tex]\frac{2}{3}[/tex]

d.)  [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Let

X be a uniform random variable that denotes the actual charging time of battery.

Given that, the actual recharging time required is uniformly distributed between 90 and 120 minutes.

⇒X ≈ ∪ ( 90, 120 )

a.)

Probability density function , f (x) = [tex]\frac{1}{120 - 90} = \frac{1}{30}[/tex] where 90 < x < 120

b.)

P(x < 110) = [tex]\int\limits^{110}_{90} {\frac{1}{30} } \, dx[/tex]

               = [tex]\frac{1}{30}[x]\limits^{110}_{90} = \frac{1}{30} [ 110 - 90 ] = \frac{1}{30} [ 20] = \frac{2}{3}[/tex]

c.)

P(x > 100 ) = [tex]\int\limits^{120}_{100} {\frac{1}{30} } \, dx[/tex]

                 = [tex]\frac{1}{30}[x]\limits^{120}_{100} = \frac{1}{30} [ 120 - 100 ] = \frac{1}{30} [ 20] = \frac{2}{3}[/tex]

d.)

P(95 < x< 110)  = [tex]\int\limits^{110}_{95} {\frac{1}{30} } \, dx[/tex]

                       = [tex]\frac{1}{30}[x]\limits^{110}_{95} = \frac{1}{30} [ 110 - 95 ] = \frac{1}{30} [ 15] = \frac{1}{2}[/tex]

Answer:

[tex]26 \div 1690 \\ = 0.0154[/tex]

Answer:

The z-score for an ACT score of 26 is 0.17.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In a particular year, the mean score on the ACT test was 25 and the standard deviation was 5.9.

This means that [tex]\mu = 25, \sigma = 5.9[/tex]

Find the z-score for an ACT score of 26.

This is Z when X = 26. So

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

[tex]Z = \frac{26 - 25}{5.9}[/tex]

[tex]Z = 0.17[/tex]

The z-score for an ACT score of 26 is 0.17.
