Step-by-step explanation:

There are 52 cards in the deck

4 kings

P(king) = king/total = 4/52 = 1/13

replacement

52 cards , 4 queens

P(queen) = queen/total = 4/52 = 1/13

P(king, replacement, queen) = 1/13 * 1/13 =1/169

There are 52 cards in the deck

4 kings

P(king) = king/total = 4/52 = 1/13

no replacement

51 cards , 4 queens

P(queen) = queen/total = 4/51 =4/51

P(king,  no replacement, queen) = 1/13 * 4/51 =4/663

√10.83x^2= √r^2

3x=r

Answer:

In the diagram, planes JMN and KLO are parallel and planes JKN and LMP are also parallel.

Step-by-step explanation:

To be parallel in geometric terms means that two planes are on opposite sides of each other and will never intersect or touch. Knowing this, we can go through the choices one by one to see if those planes are parallel.

LMP and JKL are not parallel because they intersect at point L.

JMN and JKL are not parallel because they intersect at point J.

JKN and LMP are parallel because they never intersect or touch.

JMN and KLO are parallel because they never intersect or touch.

So, planes JMN and KLO are parallel and planes JKN and LMP are also parallel.

Answer:

Step-by-step explanation:

[tex]1\dfrac{3}{4}\cdot\dfrac{7}{3}[/tex]

convert the mixed number to the improper fraction:

[tex]1\dfrac{3}{4}=\dfrac{1\cdot4+3}{4}=\dfrac{7}{3}[/tex]

multiply:

[tex]=\dfrac{7}{4}\cdot\dfrac{7}{3}=\dfrac{7\cdot7}{3\cdot4}=\dfrac{49}{12}=\dfrac{48+1}{12}=\dfrac{48}{12}+\dfrac{1}{12}=4\dfrac{1}{12}[/tex]

Answer:

r

Step-by-step explanation:

Since r is not given, the length we can be find using the Law of Sines using is length r.

The Sine formula or the Law of Sines

q/Sine Q = r/Sine R

q=9.5

r is the unknown

9.5/Sine 18° = r/ Sine 135°

With sine law length of the side opposite to the angle in a triangle can be determined i.e. r = 21.738.

∠Q measures 18°, ∠R measures 135°, and q equals 9.5, then which length can be found using the Law of Sines is to determined.

The sine formula provides the ratio of the sides and angles of a triangle. The sine rule can be explained using the expression, a/sinα = b/sinβ = c/sinФ. Here a, b, and c are the measures of the sides of the triangle, and α, β, Ф are the angles of the triangle.

Here,

sine law for given numerical,
[tex]q/sinQ = r/sinR[/tex]
Q = 18°, R = 135° and q =9.5
⇒ 9.5/sin18 = r/sin135
    30.24 * sin135 = r
     r = 21.738

Thus, with sine law, length of the side opposite to the angle in a triangle can be determined i.e. r = 21.738.

Answer:

The maximum value of (2·x - 10) is 20

Step-by-step explanation:

Given that the maximum value of f(x) = 20

f(x) = -4·x² + bx + c

We are required to find the maximum value of (2·x - 10)

f'(x) = -8·x + b = 0

x = b/8

f''(x) = -8, therefore, f'(x) is the maximum point

20 = -4·x² +8·x²  + c

20 = -4·(b/8)² + b×(b/8) + c

20 = -b²/16 + b²/8 + c

20 = b²/16 + c

f(2·x - 10) = -4·(2·x - 10)² + b·(2·x - 10) + c

f(2·x - 10) = b·(2·x - 10) + c - (16·x²-160·x +400

Differentiating to find the maximum gives;

f'(2·x - 10) = d(b·(2·x - 10) + c - (16·x²-160·x +400)/dx = 2·b -32·x +160 = 0

x = (2·b +160)/32 = 0.0625·b +5

At the maximum point, therefore, we have;

b·(2·(0.0625·b +5) - 10) + c - (16·(0.0625·b +5)²-160·(0.0625·b +5) +400

At the max value of f(2·x - 10) = b²/16 + c

Since b²/16 + c = 20, we have the maximum value of (2·x - 10) = 20.

Answer:

A,  40.16

Step-by-step explanation:

cosθ = adjacent (BC) / hypotenuse (AB)

cos 17° = BC / 42

BC = 40.16

Answer:

[tex]\boxed{BC = 40.16}[/tex]

Step-by-step explanation:

Cos 17 = [tex]\frac{adjacent}{hypotenuse}[/tex]

Where adjacent = BC, hypotenuse = 42

0.959 = [tex]\frac{BC}{42}[/tex]

BC = 0.959 * 42

BC = 40.16

Answer:

The x-intercept is the location on the graph when the output is 0.

f(x) > 0 is intervals of the domain where the graph is above the x-axis.

y-intercept is the location on the graph when the input is 0.

f(x) < 0 is intervals of the domain where the graph is below the x-axis.

Answer:

B

Step-by-step explanation:

The y-intercept (which is 2 in this case) represents the initial value. In this context that means the number of pears at the start.

Answer:

D) $270.00

Step-by-step explanation:

15% of 1800 is 270 which is exactly what the dollar amount of the discount would be

Answer:

D.) $270.00

Step-by-step explanation:

I got this by first turning 15% into its decimal form:

[tex]15%[/tex]% [tex]= .15[/tex]

Once I did this I multiplied the decimal form by the price of the motorcycle.

[tex]1,800[/tex] × ·[tex]15[/tex] = [tex]270[/tex]

Answer:

in the last one 3+4+4×15=67

in the first if we see there are three shapes if we divide 45/3 so the value of each shape is 15

in the second there are two bananas and one shape as we know the value of shape so 23-15=8 as there are two bananas so the value of each banana is 4

in the third there are two clocks and one banana as we know the value of banana so 10-4=6 as there are two clocks so the value of each clock is 3

from above

shape=15 banana=4 and clock =3 pitting in the equation gives us the value of 67

Answer:

I think the answer is b

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Recall that:

[tex]\displaystyle \cos\theta = \frac{1}{\sec\theta}[/tex]

Since we are given that secθ = -7.3, then by definition:

[tex]\displaystyle \cos\theta = \frac{1}{(-7.3)}\approx -0.14[/tex]

Next, recall that:

[tex]\displaystyle \sin\left (\frac{\pi}{2} - \theta \right) = \cos\theta[/tex]

This is the co-function identity.

And since sine is an odd function:

[tex]\sin u = -\sin (-u)[/tex]

In other words:

[tex]\displaystyle \sin\left (\frac{\pi}{2} - \theta \right) = -\sin\left(\theta - \frac{\pi}{2}\right)= \cos\theta[/tex]

Therefore:

[tex]\displaystyle \sin\left(\theta - \frac{\pi}{2}\right) = -\cos\theta = -(-0.14) = 0.14[/tex]

Hence, our answer is D.

Answer:

the fifth number is 70

Step-by-step explanation:

mean (average) of first 5 numbers =50 , Then sum of this 5 numbers = 50*5 =250.

The mean  of 4 numbers = 45 . Sum 4 numbers = 45*4 = 180

the fifth number is 250-180=70

(180 +70)/5=50 which is the mean

Answer: RV = 27 meters

Step-by-step explanation: Median is a line which unites a vertice and a midpoint of the opposite side. The point where, in a triangle, the medians intersect is called Centroid. The centroid divides the median in a ratio of 2:1, so Centroid Theorem states that the centroid of the triangle is at 2/3 of a distance from the vertex to the midpoint of the sides.

The attached figure shows the medians and centroid.

RW and WV are components of RV, the median.

If RW is 18 and following the theorem:

RW = [tex]\frac{2}{3}[/tex].RV

RV = [tex]\frac{3}{2}[/tex]. RW

RV = [tex]\frac{3}{2}.18[/tex]

RV = 27

The median RV measures 27 meters.

Answer:

1. tan20=y/600  

y=218.38ft

2.   8.08 ft

Answer:

Option (2)

Step-by-step explanation:

Let the equation of the line is,

y - y' = m(x - x')

where (x', y') is a point lying on the given line.

And m = slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Line given in the graph passes through two points (-5, -1) and (-2, -3).

Slope of the line 'm' = [tex]\frac{-3+1}{-2+5}[/tex]

                                 = [tex]-\frac{2}{3}[/tex]

Therefore, equation of the line passing through(-5, -1) and slope of the line = [tex]-\frac{2}{3}[/tex] will be,

y - (-1) = [tex]-\frac{2}{3}[x-(-5)][/tex]

[tex]y+1=-\frac{2}{3}(x+5)[/tex]

[tex]y=-\frac{2}{3}x-\frac{10}{3}-1[/tex]

[tex]y=-\frac{2}{3}x-\frac{13}{3}[/tex]

Option (2) will be the answer.
