A standard 52-card deck has four 13-card suits: diamonds, hearts, clubs, and spades. the diamonds and hearts are red, and the clubs and spades are black. each 13-card suit contains cards numbered from 2 to 10, a jack, a queen, a king, and an ace. an experiment consists of drawing 1 card from the standard deck. find the probability of drawing a black king of heartsblack king of hearts.
Answers
The probability of getting a black king of hearts is 1/52
From the question, we have:
The number of cards in a standard deck, n = 52
Black king of heart, r = 1
The probability of getting a black king of hearts is the quotient of the number of black king of heart and the total number of cards in the deck.
So, we have:
p = 1/52
Hence, the probability of getting a black king of hearts is 1/52

Answers
Answer:
use slope intercept formula
y=Mx +b
Step-by-step explanation:
3X-4Y=8
3X-8 = 4Y
y = 3/4x-2
our new equation just needs to have the same slope M= 3/4
y-y1=M(x-x1)
y-4=3/4(x-(-16))
y=3/4x+12+4
y=3/4x+16 answer a
for a perpendicular line.. just take the inverse of the slope... and change the sign. so now our slope is - 4/3
plug in our new point (9,-7)
y-(-7) = -4/3(x-9)
y+7=-4/3x+12
y= -4/3x +5 answer b
is answer 150
Answers
Answer: The answer is 150.
Step-by-step explanation:
First of all, we need to use inverse operations to solve this arithmetical equation.
First, multiply both sides by 5.
5(B/5 + 15) = 5(45).
B + 75 = 225.
Now we need to use the inverse operation of addition to get B by itself.
The inverse operation of addition is subtraction. And so we must subtract each side by 75.
B + 75 - 75 = 225 - 75.
B = 150.
So it looks like you are correct. 150 is the answer.

A statistic is a characteristic of a sample, a portion of the target population. A parameter is a fixed, unknown numerical value, while the statistic is a known number and a variable which depends on the portion of the population.
Parameter Definition: a quantity or statistical measure that, for a given population, is fixed and that is used as the value of a variable in some general distribution or frequency function to make it descriptive of that.
Population: The mean and variance of a population are population parameters.
Statistic Definiton: A statistic or sample statistic is any quantity computed from values in a sample that is used for a statistical purpose. Statistical purposes include estimating a population parameter, describing a sample, or evaluating a hypothesis. The average of sample values is a statistic.

The number of cupcakes needed to get the order to 100% is 6 cupcakes.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
60% = 9 cupcakes
Multiply 100/60 on both sides.
100/60 x 60% = 100/60 x 9 cupcakes.
100% = 5 x 3 cupcakes
100% = 15 cupcakes
Thus,
6 morecupcakes are needed.
