Answer:
The answer should be A'(-9,3) B'(12,-6)
Step-by-step explanation:
If you dialate, you multiply every coordinate by 3. -3 x 3= -9. 1 x 3=3. 4 x 3= 12. -2 x 3= -6. So, the last option is correct.

15% x 0.15x
33% y 0.33y
21% 40 0.21•40
x + y = 40 ⇒ x = 40 - y
0.15x + 0.33y = 0.21•40
0.15(40 - y) + 0.33y = 0.21•40
6 - 0.15y + 0.33y = 8.4
0.18y = 2.4
y = 13¹/₃

Step-by-step explanation:
Answer:
(76/3) / 14 OR AROUND 9/5
Step-by-step explanation:
So I'm assuming this equation is (76/9) / (14/3)
We can solve this in a simple way instead of a hard way -->
9 and 3 can cancel out to 3 and 1 so we have (76/3) / (14)
76/3 = 25 1/3 --> 25 1/3 / 14 If you simplify this it's around 1 4/5 or 9/5

80
50
Answers
Answer:
50
Step-by-step explanation:
d-nr of ducks
g- nr of goats
2*d+4*g=260
d+g=80 /*(-2)
2d+4g=260
-2d-2g=-160
------------------
2g=100
g=100/2
g=50
Answer:
50Option D is the correct option
Solution,
Let no.of ducks be X
Let no.of goats be y.
Total heads= X+y=80 ➡️ equation (i)
Total legs= 2x+4y=260➡️ equation (ii)
X= 80-y
[tex]2(80 - y) + 4y = 260 \\ or \: 160 - 2y + 4y = 260 \\ or \: 160 + 2y = 260 \\ or \: 2y = 260 - 160 \\ or \: 2y = 100 \\ or \: y = \frac{100}{2} \\ y = 50[/tex]
Number of goats= 50

Answers
6% of $14.00=$0.84 so the total cost of shorts=$14.84
6% of $25.00=$1.50 so the total cost for soccer ball=$26.50

Can you add and subtract integers and surds together?
For example:
1. 2-2√6= √6
2. 25+ 5√5 + 5√5 +5= 40√5
or are the above examples wrong?
Answers
Answer:
Both of these examples are wrong. You cannot add/subtract integers and square roots together, however, you could add square roots together if they have the same number under the square root. For example, 2 - 2√6 will stay as 2 - 2√6 because they aren't like terms. 25 + 5√5 + 5√5 + 5 = 30 + 10√5 because 25 + 5 = 30 and 5√5 + 5√5 = 10√5. We can add 5√5 and 5√5 together because they have the same number under the square root. If we were to compute √2 + √3, we would just leave it as is because they don't have the same number under the square root.

Sally Citizen is walking along the street in New York City. When she is 100 feet from the Empire State Building, she looks up at an angle of elevation of 73° and sees a window washer hanging on the side of the building. Sally’s eyes are 5 feet above the street. To the nearest foot, how high is the window washer above the street?
Answers
Answer:
332.08 feet
Step-by-step explanation:
Let h be the height of the window washer above the street
Using trigonometric ratio
[tex]\tan 73^\circ=\dfrac{h}{100}\\ h=100 \times \tan 73^\circ\\h=327.08$ feet[/tex]
The distance of the window washer above the street
=327.08+5
=332.08 feet
The window washer is 332.08 feet above the street.

If fx=-4x2-3 please evaluate for f(8), listing the steps you take in order with their result. Find the inverse function f-1(x)
Answers
Answer:
A. -259
B. inverse function is 1/2 √(-x-3)
Step-by-step explanation:
Here, we want to find f(8)
Simply substitute x = 8 in the equation.
The equation is
f(x) = -4x^2 -3
So f(8) = -4(8)^2-3
f(8) = -256-3
f(8) = -259
Inverse of f(x) = -4x^2 -3
Simply equate this to m
m = -4x^2-3
-4x^2 = m + 3
x^2 = (m + 3)/-4
x^2 = -m/4 -3/4
x = √(-m-3)/4
x = 1/2√(-m-3)
Put back the value of x for m
x = 1/2 √(-x-3)

It m triangle TOP =43°, what is mPT?
Answers
Answer:
the answer for the question is 13°
Answer: x is 25°
The measure of arcPT is 32 degrees. The measure of arcXZ is 54°
(The drawing is not to scale!)
Step-by-step explanation: The angle of the intersecting chords is
m∠ = (a + b)/2 . Use 'a' for the measure of arc PT, 'b' for the measure of arc XZ
So 43 =([x+7] +[2x + 4])/2 . Substitute the values given for a & b .
86 = 3x +11
75 = 3x
x = 25
m∠= a = x + 7
a = 32
A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 9.0, 7.3, 6.0, 8.8, 6.8, 8.4, and 6.6 pounds. What is the decision for a statistical significant change in average weights at birth at the 5% level of significance? rev: 04_14_2015_QC_CS-13524 Reject the null hypothesis and conclude the mean is lower than 6.6 lb. Fail to reject the null hypothesis. Cannot calculate because the population standard deviation is unknown. Reject the null hypothesis and conclude the mean is higher than 6.6 lb.
Answers
Answer:
Step-by-step explanation:
n = 7
Mean = (9.0 + 7.3 + 6.0 + 8.8 + 6.8 + 8.4 + 6.6)/7 = 7.6
Standard deviation = √(summation(x - mean)²/n
Summation(x - mean)² = (9.0 - 7.6)^2 + (7.3 - 7.6)^2 + (6.0 - 7.6)^2 + (8.8 - 7.6)^2 + (6.8 - 7.6)^2 + (8.4 - 7.6)^2 + (6.6 - 7.6)^2 = 8.33
Standard deviation = √(8.33/7
s = 1.1
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
H0: µ = 6.6
For the alternative hypothesis,
H1: µ ≠ 6.6
This is a two tailed test.
Since the number of samples is small and the population standard deviation is not given, the distribution is a student's t.
Since n = 7
Degrees of freedom, df = n - 1 = 7 - 1 = 6
t = (x - µ)/(s/√n)
Where
x = sample mean = 7.6
µ = population mean = 6.6
s = samples standard deviation = 1.1
t = (7.6 - 6.6)/(1.1/√7) = 2.41
We would determine the p value using the t test calculator. It becomes
p = 0.053
Since alpha, 0.05 < than the p value, 0.053, then we would fail to reject the null hypothesis.

Step-by-step explanation:
Since the fish bowl contains blue, green and red plastic fishes, it means that a fish picked at random would be any of these colors.
the probability of it being blue is 0.7 and the probability of it being green is 0.2, then probability of Matt picking a red fish is
1 - (0.7 + 0.2) = 0.1
If there are 60 fishes in the fish bowl, then the number of fishes that are red is

Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Plug in two points on the graph. We can use the points (-1, 4) and (0, 0):
