You are playing blackjack and want to know the probability of getting dealt certain cards. In blackjack two cards are drawn from a deck, the first is dealt to you face down and the second is dealt face up. Using the product rule, find the probability that (a) The bottom card is an ace or a king and the top card is red. (b) Both of the cards are clubs. (c) At least one of the cards is a jack.
Answer:
The correct answer is:
(a) 0.0784
(b) 0.0588
(c) 0.1493
Step-by-step explanation:
According to the question,
Number or ace or king,
n (ace or king) = 8
Number of red,
n (red) = 26
Number of club,
n (club) = 13
Number or jack,
n (jack) = 4
(a)
Probability of 1st ace or king and 2nd in red will be:
⇒ [tex]P(ist \ ace \ or \ king \ and \ 2nd \ red) = \frac{8}{52}\times\frac{26}{51}[/tex]
⇒ [tex]=0.0784[/tex]
(b)
Probability of both clubs will be:
⇒ [tex]P(clubs) =\frac{13C_2}{52C_2}[/tex]
⇒ [tex]=0.0588[/tex]
(c)
Probability of at least one is jack will be:
⇒ [tex]P(at \ least \ one \ is \ jack)=1-P(none \ jack)[/tex]
⇒ [tex]=1-\frac{48C_2}{52C_2}[/tex]
⇒ [tex]=0.1493[/tex]

Answer/Step-by-step explanation:
3. Volume = l*w*h = 1*3*1 = 3 ft³
Surface area = 2(lw + wh + lh) = 2(1*3 + 3*1 + 1*1) = 14 ft²
4. V = 216 cm³
w = 6 cm
l = 12 cm
h = ?
V = l*w*h
Plug in the given values and find h
216 = 12*6*h
216 = 72*h
216/72 = h
h = 3
Surface area = 2(lw + wh + lh)
= 2(12*6 + 6*3 + 12*3) = 252 cm²
5. V = 120 m³
h = 4 m
l = 5 m
w = ?
V = lwh
Plug in the given values
120 = 5*w*4
120 = 20*w
120/20 = w
w = 6 m
Surface area = 2(lw + wh + lh)
= 2(5*6 + 6*4 + 5*4)
= 148 m²
6. V = 726 in³
h = 11 in
w = 33 in.
l = ?
V = lwh
Plug in the values
726 = l*33*11
726 = l*363
726/363 = l
l = 2 in
Surface area = 2(lw + wh + lh)
= 2(2*33 + 33*11 + 2*11)
= 902 in²

One earthquake has a MMS magnitude 4.1. If a second earthquake has 540 times as much energy as the first, find the magnitude of the second quake.
Answer:
This is not the case. Instead, use the equation M = 2/3log(S/S 0), where M is the amplitude of the first earthquake and S is the seismic moment. In this instance... 2/3log(S/S 0) = 3.3 log(S/S 0) = 3.3(2/3) log(S S 0) = 4.95 ten S = 10 = 4.95 = S/S 0 4.95*S 0*S 0*S 0*S 0* 610*104.95*S 0 = S 2/3log((610*104.95*S 0)/S 0) M M = 2/3log(60*104.95) M = 2/3log(60*104.95) M = 2/3log(60 5.156887 M = 5.156887 M = 5.156887 M = 5. As a result, the magnitude of the second quake is 5.156887.

if ABCD is a rectangle find angle ABD
Answer:
61 degrees
Step-by-step explanation:
First, find x. CBD=BDA
x+18=4x-15
x=11
Four interior angles of a rectangle are all 90 degrees. So to find ABD, subtract CBD from 90 degrees. So 90-29=61 degrees.

How many miles did Byron drive? Please do not guess!
=======================================================
Explanation:
The distance from his house to the gas station is 5 miles. We can find this by counting out the number of spaces between the two points (since the chart indicates that 1 unit = 1 mile). Or we can subtract the x coordinates to get 8-3 = 5. This only works because the y coordinates of each point are the same value.
To find the distance from the gas station to the market, we subtract the y coordinates this time. This only works due to the x coordinates being the same. We get a distance of 8-3 = 5 miles.
Overall, the total distance Byron drives is 5+5 = 10 miles.

Step-by-step explanation:
an object is launched at 4 ft./s from 88 foot tall platform the objects height H in feet after T seconds is given by the equation H=-16T^2+8t+80 when does the object strike the ground
Answer:
1.5seconds
Step-by-step explanation:
When the ball hits the ground, the height is equal to zero. So find t when H=0:
H=16t²+8t+80
0=16t²+8t+80
0=2t²+t+10
0=(2t-3)(t+2)
So (2t-3)=0, or (t+2)=0
So t=1.5 or t=-2. Time can't be negative though, so we take our answer as 1.5seconds
The side length of thr hexagon is 16 centimeters,and the length of the digonal shown is 32 centimeters. Charles measured the height of one of trapezoids and found that the height of one of the trapezoids and found that the height was 13.9 centimeters. Find the area of the hexagon.
Answer:
669cm2
correct question
Charles drew a regular hexagon and divided it into two identical trapezoid , the side length of the hexagon iscoming16cm,the diagonal shown in fig 30 is 32 cm Charles measure the height of one the trapezoid and found that the height was 13.9 cm find the area of the area
Step-by-step explanation:
The side length of the hexagon should be given which is 16 cm
To get the Length the side length makes with the height of the trapezium, Pythagoras theorem is applied to get the base of the triangle
Base = √((16)^2 - (13.9)^2
Base = √62.29
Base = 7.92cm
Since we have gotten the base
Diagonal - the base gives the top length of the trapezium.
32- 7.92- 7.92 = 16.16
The area of the hexagon gives the 2 times of the trapezium.
To find the area of the trapezium
= 1/2 * ( a+b)h
= 1/2* ( 32+ 16.16)* 13.9
= 24.04*13.9
Area of the trapezium = 334.71cm2
= 334.71 * 2
= 669.42cm2

Solve the following quadratic equation for all values of x in simplest form (x+4)²+38=47
Answer:
- 1
Step-by-step explanation:
( x + 4 )² + 38 = 47
( x + 4 )² = 47 - 38
( x + 4 )² = 9
( x + 4 )² = 3²
Square root on both sides,
x + 4 = 3
x = 3 - 4
x = - 1

A cook places two thirds of a pound of garlic powder in a plastic container. This occupies one third of the space in the container. How much pounds of a powder can be stored in this container?
Answer:
1
Step-by-step explanation:
Add e
Number of pounds of a powder that can be stored in the container is 2 pounds.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator.
Given that,
Number of pounds of garlic powder placed in container = 2/3 pound
This is equal to one third of the total space in the container.
So, we can write this as,
Number of pounds of powder in 1/3 space = 2/3 pounds
Number of pounds of powder in 1 full space = 2/3 ÷ 1/3
= 2/3 × 3 (by reciprocal rule)
= 2 pounds
Hence 2 pounds can be stored in the full container.

In July, a new endoscopy and electrophysiological lab are opening up. It is projected 60 endoscopies and 5 EP studies will be performed daily. Based on preliminary work sampling to determine the time it will take to code these types of cases; it will take 5 minutes per endoscopy and 15 minutes per EP study. Calculate number of FTE needed to be hired to cover additional procedures per 7.5 hour day
Answer:
The number of FTE needed to be hired to cover the additional procedures per 7.5 day work is:
= 1.
Step-by-step explanation:
a) Data and Calculations:
Endoscopies EP Studies Total
Projected number of studies 60 5 65
Time in minutes for per study 5 15
Total time required (in minutes) 300 75 375
Full-time Employee (FTE) works 7.5-hour day or 450 minutes (7.5 * 60) per day.
b)The number of full-time employees (FTE) needed to be hired to cover the additional procedures per 7.5-day work is 1. The FTE has 450 minutes available for the additional procedures. She will only require 375 minutes. Therefore, she has extra (idle) time of 75 (450 - 375) minutes per workday.
