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

Step-by-step explanation:

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)

Answer:

  g(x) = 2sin(x) +3

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 ...

Well since you didn't give any choices, I would say the simplest way to write it would be (18 + 9) x 2

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.

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

Answer:

-2

BRAINLIEST, PLEASE!

Step-by-step explanation:

5 - 3(2a + 1) = -4a + 10

5 - 6a - 3 = -4a + 10

2 - 6a = -4a + 10

-2a = 8

a = -4

-4 + 2 = -2

Answer:

a+2 = -4+2 = -2

Step-by-step explanation:

5-3(2a+1)=-4a+10

Distribute

5 - 6a -3 = -4a +10

Combine like terms

-6a +2 = -4a +10

Add 6a to each side

-6a+2 +6a = -4a+6a +10

2 = 2a+10

Subtract 10 from each side

2-10 =2a+10-10

-8 = 2a

Divide by 2

-8/2 =2a/2

-4=a

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

What you want to do at the beginning is to "Keep-Change-Flip" the fractions. You're going to keep the first fraction the same, change the divide sign to a multiply sign, and flip the second fraction.

Next, you'll have to factor, and then you can cancel out common components.

Answer:

(3,4)

Step-by-step explanation:

Find the equation of BH.  (x+3)/(9/11+3)=(y-1)/(4/11-1)

(x+3)/(42/11)= (y-1)/(-7/11)

(x+3)*11/42= (y-1)*11/-7

x+3= -6(y-1)

x+3=-6y+6

y=-1/6x+1/2

m1=-1/6

AC:   y=m2x+b

m1*m2=-1 (for perpendicular lines)

-1/6m2=-1

m2=6

-2=6*2+b

b=-14

y=6x-14

Find CH

(x-2)/(9/11-2)= (y+2)/(4/11+2)

(x-2)/(-13/11)= (y+2)/26/11

(x-2)*-11/13=(y+2)*11/26

(x-2)(-2)=y+2

-2x+4=y+2

y=-2x+2

m3=-2

AB: y=m4x+b

m3*m4=-1

-2*m4=-1

m4=0.5

Take the point B from AB

1=-3*0.5+b

b=2.5

y=0.5x+2.5

A is the point of intersection of two linesAB and AC

We have simultaneous equations

y=6x-14

y=0.5x+2.5

6x-14=0.5x+2.5

5.5x=16.5

x=3

y=6*3-14=4
