Answer:
C. 11 is the correct answer
Step-by-step explanation:
The table representing the probabilities of player's batting average is,
Left-Handed pitchers Right-Handed pitchers
Bats Left 0.285 0.175
Bats Right 0.215 0.250
So, when the players bats left 100 times,
The probability of hits he gets when faced by left-handed pitchers = 0.285 × 100 = 28.5
The probability of hits he gets when faced by right-handed pitchers = 0.175 × 100 = 17.5
Thus, the difference in the hits = 28.5 - 17.5 = 11
Hence, the player will get 11 more hits t when he faces left-handed pitchers as opposed to right-handed pitchers.

The distance from Boulder City, NV to Santa Fe, NM is around 600 miles. If a map has a scale of 0.3 in for every 30 mi, how far is the scale distance between Boulder City, NV and Santa Fe, NM?
Answer:
6 inches.
Step-by-step explanation:
The distance between two cities is around = 600 miles.
Map has a scale of 0.3 inches = 30 miles.
Therefore, on the scale 1 inches = [tex]\frac{30}{0.3}[/tex] miles
= 100 miles
Since on the map, 100 miles = 1 inches
The distance of 600 miles = [tex]\frac{600}{100}[/tex]
= 6 inches
The scale distance between cities is 6 inches.

What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
Given explicit formula is

How large in square meters is the land area of australia (2941526 mi 2)?
Final answer:
The land area of Australia is roughly 7.62 trillion square meters, calculated by multiplying the area in square miles (2,941,526) by the conversion factor of 2,590,000 square meters per square mile.
Explanation:
The student is asking for the conversion of Australia's land area from square miles to square meters. To convert square miles to square meters, we use the conversion factor that 1 square mile is equal to 2.59 square kilometers or 2,590,000 square meters. Therefore, the land area of Australia in square meters is calculated by multiplying the area in square miles by the conversion factor:
2,941,526 mi2 × 2,590,000 m2/mi2 = 7,619,652,340,000 m2
The land area of Australia is approximately 7.62 trillion square meters.

Consider a normal population distribution with the value of σ known. (a) what is the confidence level for the interval x ± 2.88σ/ n ? (round your answer to one decimal place.) % (b) what is the confidence level for the interval x
The confidence level for the interval x ± 2.88σ/√n is approximately 99.9%. The term 'confidence level' speaks to how frequently the true value of the parameter would be inside the interval for replicated experiments. Without additional information, we cannot compute the confidence level for just 'x'.
Explanation:In statistics, a formula exists to find the confidence interval. For the interval x ± 2.88σ / √n, the confidence level is nearly 99.9%. We find this by referring to the z-table (standard normal table) with a z-score of 2.88. This leaves 0.05% in each tail of the distribution.
On the topic of confidence levels, a 95% confidence interval implies that if you were to take 100 random samples from your population, approximately 95 of those samples would capture the true population parameter.
For the other part of your question, when we talk about the interval x, it doesn't provide enough detail to calculate a confidence level. It needs to be stated in context of the standard deviation and the sample size.

Elliot buys a 5 pound package of ground beef for 12.50 varna buys a package of ground beef for 7.50 at the same unit price. What is the weight of the package
Varna's package weighs 3 pounds, priced at $7.50, matching Elliot's $12.50 package with 5 pounds at same unit price.
To find the weight of Varna's package of ground beef, we can set up a proportion based on the unit price.
Elliot's package:
Price: $12.50
Weight: 5 pounds
Varna's package:
Price: $7.50 (same unit price as Elliot's)
Weight: Let's call it x pounds
We can set up the proportion:
[tex]\[\frac{12.50}{5} = \frac{7.50}{x}\][/tex]
Now, we can cross multiply:
[tex]\[12.50x = 5 \times 7.50\]\[12.50x = 37.50\][/tex]
Now, let's solve for \( x \):
[tex]\[x = \frac{37.50}{12.50}\]\[x = 3\][/tex]
So, the weight of Varna's package of ground beef is 3 pounds.

x = −3.25 and x = 9.25
y = −4.25 and y = 8.25
y = −3.25 and y = 9.25
Answer:
The directrix of the ellipse is:
x= -3.25 and x=9.25
Step-by-step explanation:
As we know that for any ellipse equation of the type:
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] and a>b
The directrix is given by:
[tex]x=h\pm \dfrac{a}{e}[/tex]
where,
[tex]e=\sqrt{1-\dfrac{b^2}{a^2}}[/tex]
Here we have the equation of parabola as:
[tex]\dfrac{(x-3)^2}{5^2}+\dfrac{(y-2)^2}{3^2}}=1[/tex]
Hence, we have:
[tex]h=3,\ k=2,\ a=5,\ b=3\\\\and\\\\e=\sqrt{1-\dfrac{3^2}{5^2}}\\\\e=\sqrt{1-\dfrac{9}{25}}\\\\e=\sqrt{\dfrac{25-9}{25}}\\\\\\e=\sqrt{\dfrac{16}{25}}\\\\e=\dfrac{4}{5}[/tex]
Hence, we have: the directrix as:
[tex]x=3\pm \dfrac{5}{\dfrac{4}{5}}\\\\\\x=3\pm \dfrac{25}{4}\\\\Hence, x=9.25\ and\ x=-3.25[/tex]

A cone is cut parallel to its base. Write the best name for the plane section (or cross section).
Final answer:
A cone cut with a plane parallel to its base forms a circular cross section, a concept that is part of the study of conic sections.
Explanation:
When a cone is cut with a plane parallel to its base, the cross section or plane section that is created is a circle. This concept falls under the study of conic sections, which also includes other shapes like ellipse, parabola, and hyperbola, all of which are formed by the intersection of a plane with a cone. If the cut is made closer to the apex, the circle will be smaller, and if it's made closer to the base, the circle will be larger, but all such cross sections remain circular as long as the cut is parallel to the base.
Caitlyn has a credit card with a spending limit of $1500 and an APR (annual percentage rate) of 18%. During the first month, Caitlyn charged $375 and paid $250 of that in her billing cycle. Which expression will find the amount of interest Caitlyn will be charged after the first month?
The interest that will be charged after the first month is $1.875, calculated by multiplying the remaining balance of $125 by the monthly interest rate of 1.5%.
Explanation:The subject at hand is centered around the concept of credit card interest calculation. In Caitlyn's case, the remaining balance after her payment is $375 - $250 which equals $125. This is the amount that will incur interest.
The APR (annual percentage rate) is 18%, but we must first convert this to a monthly rate by dividing by 12, which equals 0.015 (or 1.5%). The interest charged after the first month is calculated by multiplying the remaining balance by the monthly interest rate. Therefore, the formula to calculate the interest is $125 * 0.015, which equals $1.875.

Which number line shows the solution to
11x + 14 < –8?
Answer:
D!!
Step-by-step explanation:
Hope it helps!!
The solution to the inequality 11x + 14 < -8 is x < -2. On a number line, this would be a circle at -2 with a line extending to the left.
Explanation:To find the solution to the inequality 11x + 14 < –8, we will first subtract 14 from both sides, which gives us:
11x < -8 - 14
This simplifies to 11x < -22.
Next, we divide both sides by 11 for: x < -2
The solution is x < -2. On a number line, this would be represented by a circle around -2 (not filled in, because the inequality does not include 'equal to') with a line extending to the left (indicating 'less than').
