Complete question :
Seven cards are drawn from an ordinary deck. In how mnat ways is it possible to draw (a) only 5s (b)only 8s, 9s, and 10s, (c) no 8s, 9s, and 10s (d) exactly 2 jacks or kings, (e) 5 spades and 2 hearts?
Answer:
0; 792 ; 100396 ; 30408224 ; 18643560 ;
Step-by-step explanation:
Number of cards in a deck = 52
Number of cards to be drawn = 7
Using combination:
nCr = n! ÷ (n-r)!r!
A.)
Number of 5's in a deck = 4
4C7 = 0
(B.)
only 8s, 9s, and 10s,
Number of 8, 9 and 10's = 4 *3 = 12
12C7 = 12! ÷ 5!7! = 792
(C)
no 8s, 9s, and 10s ;
Number of cards to select from = 52 - (3(4)) = 40C7 = 18643560
(D)
exactly 2 jacks or kings,
Number of jack or king in deck = 8 ; other 5 could be any of the rest : (52 - 8) = 44
8C2 * 44C5 = 28 * 1086008 = 30408224

A muralist is painting the side wall of a building. The wall is shaped like a rectangle that is 60
feet long and has a diagonal length of 68 feet. If a gallon of paint can cover 800 square feet,
how many gallons will the muralist use?
Answers
Answer:
2.4 gallons
Step-by-step explanation:
to answer this question :
we have to determine the width of the rectangle.
determine the area
determine the gallons needed
Pythagoras theorem would be used to determine the width of the wall
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
60² + b² = 68²
3600 + b² = 4624
b = ²4624 - 3600 = 1024
√b = 32
Area of a rectangle = length x width
32 x 60 = 1920
Gallons needed = 1920 / 800 = 2.4 gallons
The Lane School sold 1,152 granola bars to raise money for digital cameras. All the granola bars were either berry bars or raisin bars. They sold 528 berry bars, and the rest were raisin bars. The granola bars came in boxes of 24 bars. How many boxes of raisin bars did they sell?
Answers
Answer:
26 boxes of raisin bars
Step-by-step explanation:
Take the total bars sold 1152 then subtract the berry bars 528 and you'll get 624. Next you'll divide the 624 by 24 because that's how many that's in a full box. Finally you'll get your answer of 26 boxes.
1152-528=624 ➗ 24 = 26

The ratio 2/8 could represent which of the following?
A) 8 parts that are one fourth each
B) 4 parts that are one-half each
C) 2parts that are one eighth each
D) 2 parts that are one fourth each
Answers
Answer:
C) 2parts that are one eight each.
Step-by-step explanation:
The reason I chose C) as the correct answer is becasue I evaluated it with the steps below.
A) - 8 parts that are one fourth each.
This cannot be correct because it would surpase the 2/8ths (would be over).
B) - 4 parts that are one-half each.
This cannot be correct because it would surpass the 2/8ths (would be over).
C) - 2parts that are one eight each.
This can be correct because 2 parts have 1/8th. 1/8 + 1/8 = 2/8.
D) - 2parts that are one fourth each.
This cannot be correct because the denominator is not 8, it is 4 meaning it wouldn't fit into the format the question asked for (which was 2/8).
This makes the correct answer C).

Answer:
x⁰ = 45⁰
Step-by-step explanation:
As it is given that the 2 sides of a triangle are equal, then it is an isosceles triangle.
Now, by applying the Triangle Sum Property,
x⁰ + 90⁰ + 45⁰ = 180⁰
x⁰ = 180⁰ - 135⁰
x⁰ = 45⁰
Hope it helps :)
Answer:
x = 45 degrees
Step-by-step explanation:
A triangle is always 180 degrees. One angle is already labeled 45 degrees, and we can tell this is a right triangle, so the other angle is 90 degrees. Add 45 + 90 to get 135. Then subtract 135 from 180 to get 45, which is the value of the missing angle.
A regional highway uses 8 tollbooths that are open to all vehicles. A chi-square goodness-of-fit test using a significance level of α=0.05 was conducted to determine whether the tollbooths are all used in equal proportions. A chi-square value of χ2=19.1 was calculated with a corresponding p-value of 0.008. Which of the following is correct?
A. There is insufficient evidence to suggest that the tollbooths are not used in equal proportions.
B. There is insufficient evidence to suggest that the tollbooths are used in equal proportions.
C. There is sufficient evidence to suggest that the tollbooths are not used in equal proportions.
D. There is sufficient evidence to suggest that the tollbooths are used in equal proportions.
E. The tollbooths are used in equal proportions.
Answers
Answer:
C) There is sufficient evidence to suggest that the toll booths are not used in equal proportions.
Step-by-step explanation:
First of all, we have to understand that this is a question asking to draw a conclusion from the chi-square GOF (goodness of fit) test information that was given in the problem text.
From there, we use the usual sentence format, and in this case, we use the sentence format for when the p-value is less than α:
Since the p-value (0.008) is less than the alpha value (0.05), we reject the null hypothesis ([tex]H_0[/tex]). There is sufficient evidence to suggest that the toll booths are not used in equal proportions.
To elaborate, we get this answer by knowing that since the p-value is so low, the chance of getting a test statistic that extreme (too low or too high depending on the context) is significantly unlikely.
The correct option regarding the significance level is C. There is sufficient evidence to suggest that the toll booths are not used in equal proportions.
How to explain the significance level?In this question, we simply have to deduce a conclusion from the chi-square test information that was given.
In this case, the p-value (0.008) is simply less than the alpha value (0.05), therefore, we will reject the null hypothesis.
This implies that there is sufficient evidence to suggest that the toll booths are not used in equal proportions.

Answers
Answer:
You will pay 70% of the original price. You will pay $17.50
Step-by-step explanation:
100% is full price because 100%=1 (one whole).
100% - 30% = 70%
70% = 0.7
0.7 multiplied by $25 is $17.50
