Answer:

-5, 3

Step-by-step explanation:

8x + 3 > 2x - 15

8x - 2x > -15 - 3

6x > -18

x > -3

Answer:

x > -3

Step-by-step explanation:

8x + 3 > 2x - 15​

Add -3 and -2x on both sides.

8x - 2x > -15 - 3

6x > -18

Divide 6 into both sides.

x > -18/6

x > -3

Step-by-step explanation:

The total cost of rents is $180.

In the given table,

The cost of skis per day  = $48

The cost of pole per day = $12

Now since given that,

Alveres rents for 3 days

Therefore,

The cost of skis for 3 days  = $48 x 3

                                             =  $144

The cost of pole for 3 days = $12 x 3

                                             = $36

To find the total cost of rental,

Adding the cost of 3 days of skis and cost of 3 days of poles,

Hence,

Total cost of rents = $144 + $36

                               = $180

The value of angle C in given quadrilateral ABCD is 107⁰.

The measure of angle C is calculated by applying the following rule of geometry for a quadrilateral as shown below.

Angle A + Angle C = 180 (opposite angles of a quadrilateral are supplementary).

We know the value of angle A, and we are to find the value of angle C as shown below.

C + (2x + 3) = 180

C = 180 - 2x - 3 ------- (1)

Using the knowledge of sum of angles in a quadrilateral, we will calculate the value of x:

A + B + C + D = 360

2x + 3 + 2x - 4 + (180 - 2x - 3) + 3x + 9 = 360

5x + 185 = 360

5x = 175

x = 175/5

x = 35

Angle C = 180 - 2x - 3

= 180 - 2(35) - 3

= 180 - 73

= 107⁰

Answer:

Step-by-step explanation:

Probability that a junior is in algbera or geometry = (Probability that a junior is in algbera + Probability that a junior is in geometry) - (Probability that the student is in both algbera and geometry)

Mathematically, we can rewrite the above statement as:

Pr(A or G) = Pr(A) + Pr(G) - P (A & G)

where A = Algbera

G = Geometry

Pr(A) Probability that a junior is in algbera = No of students in algebra class/ Total number of students

Pr(A) = 78/200 = 0.39

Pr(G) Probability that a junior is in geometry = No of students in geometry/ Total number of students

Pr (G) = 85/200 = 0.425

P ( A & G) Probability that the student is in both algebra and geometry = No of students in both algebra and geometry/ Total number of students

P(A & G) = 14/200 = 0.07

Pr(A or G) = (Pr(A) + Pr(G) ) - P (A & G)

Pr(A or G) = (0.39 + 0.425 ) - 0.07

Pr (A or G) = 0.815 - 0.07

= 0.745

Therefore the probability that a junior is in algbera or geometry is 0.745

Answer:

80°, 40° and 60°

Step-by-step explanation:

Name the second angle X and the first angle to 2X (because it is twice the measure of angle number two) and the third angle to 20°+X (because it was 20° more than the second angle)

so we will have an equation of

180°=2x + x + (20°+x)

160°=4x

40°=x

so the second angle is 40° as it is represented by just one X

therefore the first angle which is twice the measure is 80° and the third angle which is 20° more is 60°. hope that helps!

Answer:

0.28

Step-by-step explanation:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

\(z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation,x=raw \ score\)

From the normal distribution table, the z score that corresponds to the bottom   60.94% (0.6094) = 0.28.

Answer:

D. 4 root 113

Step-by-step explanation:

we have to use Pythagorean Theorem which is

a^2 + b^2 = c^2

where a and b are legs of the triangle that are 45° apart and c is the hypotenuse.

now we just plug in our values.

a^2 + (9)^2 = (47)^2

a^2 + 81 = 2209

now we're gonna solve for A (the missing side)

a^2 = 2128

now we square root both sides to undo the square on A

root(a^2) = root(2128)

because 2128 isn't a pretty root, we have to simplify it

a = 4 root(133)

Answer:

1.16667

Step-by-step explanation:

When told in the question that random number of sample is tested

z test statistic formula = x - x bar(x with bar above it) /Standard error

From the question

x = raw score = 46 pounds

x bar (x with bar above it)= sample mean = 45.5 pounds

Standard Error = σ/√n

Standard deviation = σ = 3

n = random number of samples = 49

z = 46 - 45.5/3/√49

z = 0.5/ 3/7

z =0.5/ 0.4285714286

z = 1.16667

Therefore , the value of the z test statistic = 1.16667
