Two cards are drawn from a pack of 52 cards one by one without replacement; that is, the first card is not replaced before the second card is drawn. What is the probability of the second card being a king of spades if the first card is a king of club

Answers

Answer:

The probability is 1/51

Step-by-step explanation:

In a deck of cards, there are 52 cards

one king of spades and one king of club

If the first is a king of club, after drawing it, the number of cards that we will have left will be 52-1 = 51 cards

So the probability that the second is a king of spades is the number of king of spades/number of remaining cards

Mathematically that will be 1/51

Tiana compares the length of a name on a nameplate to the number of letters in the name. She draws the scatterplot below, and then she plots and determines an equation for the trend line. Nameplates A graph has letters on the x-axis and length (inches) on the y-axis. A trend line goes through points (2, 5) and (4, 8). The regression equation is y = 1.47 x + 2.05. Based on the information above, which is the best estimate of the number of letters that a name contains if the nameplate is 6 inches long? 3 4 10 12

Answers

Answer:

3

Step-by-step explanation:

The best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

What is a scatter plot?

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

It is given that, the regression equation is y = 1.47 x + 2.05.

The name's letter count is represented by variable x, whereas the name's length on a nameplate is represented by variable y.

The nameplate is 6 inches long, so y=6 and you can find x by doing the following:

6=1.4x+2.05

1.4x=6-2.05

1.4x=3.95

x=2.69

x≈3

Thus, the best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

2. A proportional relationship has a constant rate of change.

ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.

the answer would be A. -18x^7

hope this helps:)

Answer:

[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]

Hence, option (A) is true.

Step-by-step explanation:

Given the expression

[tex]-6x^2\left(3x^5\right)[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

i.e. [tex]x^2x^5=\:x^{2+5} \\[/tex]

so the expression becomes

[tex]-6x^2\left(3x^5\right)=-6\cdot \:\:3x^{2+5}[/tex]

[tex]\mathrm{Add\:the\:numbers:}\:2+5=7[/tex]

                  [tex]=-6\cdot \:3x^7[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:6\cdot \:3=18[/tex]

                   [tex]=-18x^7[/tex]

Therefore,

[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]

Hence, option (A) is true.

Denise bought 116 ounces of beans for a bean dip. She bought both 15-ounce cans and 28-ounce cans, and the total number of cans she bought was 6. Which of these systems of equations can be used to determine the number of 15-ounce cans and the number of 28-ounce cans that she bought? Assume x represents the number of 15-ounce cans and y represents the number of 28-ounce cans.
x + y = 6. 15 x + 28 y = 116.
x + y = 6. 28 x + 15 y = 116.
x + y = 116. 15 x + 28 y = 6.
x + y = 116. 28 x + 15 y = 6.
