Find the equation of a line that passes through the point (-2,4) and has a gradient of -3.
Leave your answer in the form
y
=
m
x
+
c
Answers
Equation of a line is y = mx +c
m is the gradient, which is given as -3 so now you have:
y = -3x + c
Replace y and x with the given point and solve for c:
4 = -3(-2) + c
Simplify:
4 = 6 + c
Subtract 6 from both sides:
c = -2
The equation becomes:
y = -3x-2
The square pyramid shown below has a base with sides of 10 units. The slant height of the pyramid is 8 units. What is the vertical height, h?
Answers
Make a right triangle by using half the base and using the Pythagorean theorem calculate the height.
Height = sqrt(8^2 - 5^2)
Height = sqrt(64 - 25)
Height = sqrt(39)
Height = 6.245 ( Round the answer as needed).
Answer:
6.2
Step-by-step explanation:
We can use the Pythagorean Theorem to find h.
The equation for the Pythagorean Theorem is a^2+b^2=c^2
We see that the hypotenuse of the right triangle is 8. One leg is h. The other leg is 5 , which is half the length of the base.
We have:
a^2+b^2=c^2
5^2+h^2=8^2
25+h^2=64
h^2=39
h= square root of 39
h = 6.244

Transformation of parent Functions I need help
Answers
Answer:
D: ∛(¼(x + 5))
Step-by-step explanation:
The parent function is;
f(x) = ∛x
A horizontal stretch multiplying by ¼ means that our function is now;
f(x/4) = ∛(x/4)
Now shifting to the left by 5 units denotes;
f(x + 5) = ∛((x + 5)/4)
Or expressed as; ∛(¼(x + 5))

Xuan sold 9 used books for $9.80 each. With the
money from these sales, she bought 4 new books and
had $37.80 left over. What was the average amount
Xuan paid for each new book?
A. $ 5.60
B. $ 9.45
C. $10.08
D. $12.60
E. $22.05
Answers
Answer:
I think the answer is A, $5.60
Step-by-step explanation:
9.80 x 9= 88.20
88.20 - 37.80 = 50.40
5.60 x 9 = 50.40
The average amount paid for the books is $12.60
Since Xuan sold 9 used books for $9.80 each, the total amount that's paid for the books will be:
= $9.80 × 9
= $88.20
Since she bought 4 new books and had $37.80 left over, the cost of the books will be
= $88.20 - $37.80
= $50.40
Since she bought 4 books, the average amount paid for the books will be:
= $50.40/4
= $12.60
Therefore, the correct option is D

In the last year, U.S. car sales of all makes and models have dropped by 16%. Let's say that a car dealer sells 325 cars. If this number drops by 16%, how many cars will the dealer sell then? Round to the nearest whole number.
A 203 cars
B 309 cars
C 273 cars
D 256 cars
Answers
Answer:
c. 273 cars
Step-by-step explanation:
First you need to find what 16% of 325 is
325x.16=52
because the number sold dropped by 16% you will subtract 52 from 325
325-52=273
you can also calculate the answer by subtracting 100% by 16%
100%-16%=84%
now you can calculate 84% of 325
325x.84=273

Step-by-step explanation:
trust me i got it right Plato
The value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.
What is a confidence interval for population standard deviation?It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.
The formula for finding the confidence interval for population standard deviation as follows:
[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]
Where s is the standard deviation.
n is the sample size.
[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex] are the constant based on the Chi-Square distribution table:
α is the significance level.
σ is the confidence interval for population standard deviation.
Calculating the confidence interval for population standard deviation:
We know significance level = 1 - confidence level
It is given that:
The value needed to determine a confidence interval for a sample mean is the standard error of the mean.
CI = X + Z(s/√n)
Here CI is the confidence interval
Z is the confidence level
X is the sample mean
Thus, the value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.

In parallelogram ABCD, the measure of angle A is 99°. What are the measures of the other 3 angles? Explain how you know.
Answers
Answer:
B:81
C:99
D:81
Step-by-step explanation:
In a parallelogram, opposite angles are congruent and consecutive angles (angles next to each other) are supplementary, or add to 180. Considering that there is no diagram, we can use our imagination here. So B is next to A, so <A+<B=180. <B must equal 81. I repeated this process for the rest of the angle measures.
[tex]\\ \sf\longmapsto <A=<C=99°[/tex]
sum of corresponding angles is 180°
[tex]\\ \sf\longmapsto <A+<B=180[/tex]
[tex]\\ \sf\longmapsto 99+<B=180[/tex]
[tex]\\ \sf\longmapsto <B=180-99[/tex]
[tex]\\ \sf\longmapsto <B=81[/tex]
[tex]\\ \sf\longmapsto <B=<D=81°[/tex]

Complete question :
A business owner wants to know if it will be profitable to open a new coffee shop in a nearby town.In towns where the shop has been successful,the shop name is recognizable to people 53% of the time .He survey random sample of 12 residents of the town. Find the probability that among these 12 surveyed residents, none of them have ever heard of the coffee shop
Answer:
0.000116
Step-by-step explanation:
Using the binomial probability relation :
Probability of success, p = 0.53
1 - p = 0.47
Number surveyed, n = 12
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability that none has heard of the coffee shop :
P(x = 0) = 12C0 * 0.53^0 * 0.47^12
P(x = 0) = 0.000116
