Answer:

48/52

Step-by-step explanation:

The probability of picking up an ace in a 52 deck of cards is 4/52 since there are 4 aces in the deck. The odds of picking up any other card is therefore $52/52 - 4/52 = 48/52.$

I hope this helps and have a great day!

Solve the equation 3x-4=8-x

solmaris [256]

Answer:

x=3

Step-by-step explanation:

3x-4=8-x(Group like terms)

3x+x=8+4(Add both sides)

4x=12(After adding you will proceed to divide both sides by 4)

x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)

If f(x)=square root 4x+9+2, which inequality can be used to find the domain of f(x)?

jenyasd209 [6]

we have

$f(x)=\sqrt{4x+9} +2$

we know that

The radicand must be greater than or equal to zero

$4x+9 \geq0 \\ 4x\geq -9 \\x\geq -\frac{9}{4} \\ x\geq -2.25$

the domain is is the interval--------> [-2.25,∞)

therefore

the answer is

$4x+9 \geq0$

100% because

a pine tree that is 140 feet tall is added to the sample. how will this outlier affect the shape of the box plot?

enot [183]

Answer:

D. The new box plot will be positively skewed.

Step-by-step explanation:

We have been given a box plot which represents the the heights (in feet) of a sample of pine trees.

We are asked to determine that affect of adding a pine tree that is 140 feet tall to the sample.

We can see from our box plot that the tallest pine tree is 75 feet and 140 is approximately 2 times greater than 75.

After adding the a tree that is 140 feet tall, the maximum height will be 140 and our right whisker will be at point 140.

Since we know that for a positive skewed data, the tail of the distribution is longer on the right hand side.

As 140 is a extreme positive outlier for our given data set, therefore, after adding a tree that is 140 feet tall our box plot will be positively skewed and option D is the correct choice.
