Calculate the area of the triangle.
Note: Think about which side to use as the base.
Answers
9514 1404 393
Answer:
27 square units
Step-by-step explanation:
The height is measured perpendicular to the base, so it is convenient to use a base such that the height is easily found. Here, the vertical line is a suitable base, as the height is the horizontal distance from that to the opposite vertex.
A = 1/2bh = 1/2(9)(6) = 27 . . . . square units = triangle area
The length of a rectangle is 2 cm more than 5
times the width. The perimeter is 196 cm. Find
the width and length.
Answers
length = 82 cm
width = 16 cm
Step-by-step explanation:
x = length
y = width
the perimeter of a rectangle is the lengths of all sides added together. so, 2×length plus 2× width
x = 5y + 2
196 = 2x + 2y
let's use the first equation as substitute in the second equation.
196 = 2×(5y + 2) + 2y = 10y + 4 + 2y = 12y + 4
12y = 192
y = 16 cm
x = 5y + 2 = 5×16 + 2 = 80 + 2 = 82 cm

Step-by-step explanation:
The transformation g(x) = c·f(x) +k represents a vertical scaling by a factor of c and a vertical shift by k units. You want the scale factor to be 2 and the vertical shift to be +3, so the transformed function is ...

The average ticket price for a Spring Training baseball game is $32.61, with a standard deviation of $8.62. In a random sample of 40 Spring Training tickets, find the probability that the mean ticket price exceeds $35. (Round your answer to three decimal places)
Answers
Using the normal probability distribution and the central limit theorem, it is found that there is a 0.04 = 4% probability that the mean ticket price exceeds $35.
------------------------------------------
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
------------------------------------------
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
------------------------------------------
The average ticket price for a Spring Training baseball game is $32.61, with a standard deviation of $8.62.
This means that [tex]\mu = 32.61, \sigma = 8.62[/tex]
------------------------------------------
Sample of 40:
This means that [tex]n = 40, s = \frac{8.62}{\sqrt{40}}[/tex]
------------------------------------------
In a random sample of 40 Spring Training tickets, find the probability that the mean ticket price exceeds $35.
This is 1 subtracted by the p-value of Z when X = 35, so:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{35 - 32.61}{\frac{8.62}{\sqrt{40}}}[/tex]
[tex]Z = 1.754[/tex]
[tex]Z = 1.754[/tex] has a p-value of 0.96.
1 - 0.96 = 0.04
0.04 = 4% probability that the mean ticket price exceeds $35.

15. Ankita bought 20 copy for Rs. 25 each. She got profit of Rs.200 while selling it. Find selling price of the copies.
Answers
Answer:
S.P = 225
Explanation:
Cost Price = 20 copies for Rs. 25
Selling price = 20 copies for ?
Profit = Rs. 200
Profit = S.P -C.P
Profit + C.P = S.P
200 + 25 = S.P
225 = S.P

remember questions like "if 1 apple costs $1.10, how much are 2 apples or 5 or 10 apples ?"
you remember what you had to do ?
pretty common sense : you multiplied the price by the same number that you multiplied the unit count number with. so, in my example, by 2, by 5 and by 10. and you got $2.20, $5.50 and $11.00 as prices.
so, what do you think we need to do to calculate the miles that are residents by 2 cm on the map ?
right ! we need to multiply by 2 - because 2×1 = 2.
so, 4.5 × 2 = 9 miles
yes, if 1 cm on the map stands for 4.5 actual miles, then 2 cm stand for 2×4.5 = 9 actual miles.

An ordered pair is simply the x-coordinate and the y-coordinate of a point.
The ordered pair of the bullseye is (4,-2.5)
From the given image (see attachment), we have:
[tex](x_1,y_1) = (9,3)[/tex]
[tex](x_2,y_2) = (-1,-8)[/tex]
The bullseye is at the midpoint of these two points.
So, the ordered pair of the bullseye is calculated using the following midpoint formula.
[tex](x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
So, we have:
[tex](x,y) = (\frac{9-1}{2},\frac{3-8}{2})[/tex]
[tex](x,y) = (\frac{8}{2},\frac{-5}{2})[/tex]
[tex](x,y) = (4,-2.5)[/tex]
Hence, the ordered pair of the bullseye is (4,-2.5)
