instructions: Find the slope of the line through the points (6, 16) and \ -6,4) Make sure to simplify fractions and enter your answers with a foward slash (i.e. "/"). If the slope is undefined enter "undefined."
9514 1404 393
Answer:
1
Step-by-step explanation:
The slope formula is useful for this.
m = (y2 -y1)/(x2 -x1)
m = (4 -16)/(-6 -6) = -12/-12
m = 1
The slope of the line through the given points is 1.
Suppose you can make your own ice cream cone by choosing the type of cone, the flavor of ice cream, and the toppings. The number of choices is 4 cones, 6 flavors, and 14 toppings. What principle would you use to determine how many different dinner menus can be chosen?
Answer:
ELHLADOE
Step-by-step explanation:
The number of ways using permutation and combination of ice cream is = 4*6*14 ways.
What are permutation and combination?The distinctive methods of arranging a set of items right into a sequential order are termed Permutations. one of the several methods of choosing items from a massive set of gadgets, without thinking about an order is termed a mixture.
mixture and permutation are extraordinary methods of grouping elements of a set into subsets. In aggregate, the factors of the subset may be listed in any order. In a permutation, the elements of the subset are indexed in a particular order.
explanation:
using multiplication rule of probability.
=The number of choices is 4 cones
= The number of choices of flavour = 6
= The number of choices topping = 14
Hence total combination is = 4*6*14

Find the standard form of the equation of the circle with endpoints of a diameter at the points (7,8) and (-3,6). Type the standard form of the equation of this circle
Answer:
The equation of the circle is [tex](x - 2)^2 + (y - 7)^2 = 21[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle, with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Diameter at the points (7,8) and (-3,6).
The diameter is the distance between these two points, so:
[tex]D = \sqrt{(-3-7)^2+(6-8)^2} = \sqrt{104}[/tex]
Radius is half the diameter, so:
[tex]r = \frac{\sqrt{104}}{2} = \frac{\sqrt{104}}{\sqrt{4}} = \sqrt{\frac{104}{4}} = \sqrt{21}[/tex]
So
[tex]r^2 = (\sqrt{21})^2 = 21[/tex]
Center:
Midpoint of the diameter, which is the mean of the coordinates. So
[tex]x_0 = \frac{7 - 3}{2} = \frac{4}{2} = 2[/tex]
[tex]y_0 = \frac{8 + 6}{2} = \frac{14}{2} = 7[/tex]
Then
[tex](x - 2)^2 + (y - 7)^2 = 21[/tex]
A quality control inspector has drawn a sample of 10 light bulbs from a recent production lot. Suppose 20% of the bulbs in the lot are defective. What is the probability that exactly 6 bulbs from the sample are defective? Round your answer to four decimal places.
Answer:
33.33 repeating percent.
Step-by-step explanation:
So using the 20 percent, we can guess there will be 2 bulbs that are defective in the sample. So 2/10. But we are guessing there will be 6;6/10. We alreadly know the proablity of that is low. To be exact 2/6 (as they are both over ten we can get rid of that) or 1/3, or 33.333 repeating percent.

Need help ASAP! What is the value of X? :)
Answer:
x = 46
Step-by-step explanation:
Since the angle that is not marked is a vertical angle, is must be the same in each triangle
The sum of each triangle is 180, set them equal and subtract the same angle from each side, this leaves the equation
53+85 = x+92
138 = x+92
138-92 =x
46 =x

In the accompanying diagram, triangle ABC is similar to triangle RST, BC= 12, AC=15, and ST= 8. Find RT.
Answer:
10
Step-by-step explanation:
ABC is similar to RST,
so BC is corresponding to ST, and AC is corresponding to RT
BC=12 and ST=8
so the scale factor from RST to ABC is 1.5 and the scale factor from ABC to RST is 2/3 because 12*(2/3) is 8, and 8*1.5 is 12.
now apply this to AC to find RT
AC=15
15*(2/3)=10
10*1.5=15
RT =10

f(x) = 3x - 4
f(x + 2)
Answer:
f(x + 2) = 3x + 2
Step-by-step explanation:
Simply replace wherever you find x in the function f(x) with (x + 2), like so:
f(x + 2) = 3(x + 2) - 4
f(x + 2) = 3x + 6 - 4
f(x + 2) = 3x + 2

The angle measurement is reasonable. It must be less than 180 which is a straight line
Step-by-step explanation:
Vertical angles are equal
3x = x+104
Subtract x from each side
3x-x = x+104-x
2x = 104
Divide by 2
2x/2 = 104/2
x = 52
3x = 3*52 = 156
The angle measurement is reasonable. It must be less than 180 which is a straight line

graph the following inequality
[tex]7x - y \geqslant 14[/tex]
PLEASE HELP ME !
Answer:
I can't exactly draw this out on this website, but I can tell you how to do it:
First, solve the inequality so it resembles a function:
7x - y ≥ 14
-y ≥ -7x + 14
y ≤ 7x - 14 (Both side multiply by -1)
Then, graph y = 7x - 14
Draw a straight line (Don't do the dotted lines because it's not > or <)Here's a couple of points to get started: (0, -14), (1, -7)Finally, because y is less than/equal to 7x - 14, shade in the area under/below the line(where the y-values are smaller).

Answer:
384 square yards
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW . . . . . where L and W stand for Length and Width
Using the given dimensions, you find the area to be ...
A = (24 yd)(16 yd) = 24×16 yd² = 384 yd²
The area of the figure is 384 square yards.
The function f(x) is shown in this graph.
(0,2)
The function g(x) = -5x - 6. Compare the slopes.
A. The slope of f(x) is the same as the slope of g(x).
B. The slope of f(x) is undefined, and the slope of g(x) is negative.C. The slope of f(x) is greater than the slope of g(x).D. The slope of f(x) is less than the slope of g(x).
Answer:
D. The slope of f(x) is less than the slope of g(x).
Step-by-step explanation:
✔️Slope of f(x):
Using two points on the line, (0, 2) and (1, -1),
Slope (m) = change in y/change in x
Slope (m) = (-1 - 2)/(1 - 0) = -3/1 = -3
Slope of f(x) = -3
✔️Slope of g(x) = -5x - 6:
The slope of g(x) is -5.
Therefore f(x) has a lesser absolute slope value (3) compared to the absolute slope value of g(x) (5).
Thus, D. the slope of f(x) is less than the slope of g(x).
The mean annual premium for automobile insurance in the United States is $1,499. Being from Pennsylvania, you believe automobile insurance is cheaper there and wish to develop statistical support for your opinion. A sample of 25 automobile insurance policies from the state of Pennsylvania showed a mean annual premium of $1,440 with a standard deviation of s = $150.
a. Develop a hypothesis test that can be used to determine whether the mean annual premium in Pennsylvania is lower than the national mean annual premium.
b. What is a point estimate of the difference between the mean annual premium in Pennsylvania and the national mean (to the nearest dollar)?
Answer:
a) Then, t(s) is in the rejection region. We can not support that the mean annual premium in Pennsylvania is lower than the national mean annual premium
b) The point estimate of the difference is 59 $
Step-by-step explanation:
From sample we get:
sample size n = 25
annual mean x = 1440
standard deviation of the sample s = 150
mean for the mean annual premium μ = 1499
Hypothesis Test:
Null Hypothesis H₀ x = μ
Alternative Hypothesis Hₐ x < μ
Alternative Hypotesis indicates that the test is a one-tail test to the left
Let´s assume confidence Interval 95 % then α = 5 % α = 0.05
As n < 30 and we assume normality we will make a t-student test
degree of freedom df = n - 1 df = 24
With df = 24 and α = 0.05 and from t-student table we get t(c) = - 1.711
To calculate t(s) we apply:
t(s) = ( x - μ ) / s/√n
t(s) = ( 1440 - 1499 ) * 5 / 150
t(s) = - 59/ 30
t(s) = - 1.96
Comparing t(s) and t(c)
|t(s)| > |t(c)|
Then, t(s) is in the rejection region. We can not support that the mean annual premium in Pennsylvania is lower than the national mean annual premium.
b) The point estimate for the difference is : x - μ = 59 $

sum of the arithmetic sequence 8,14,20 if there are 24 terms
Answer:
1,848
Step-by-step explanation:
Find the arithmetic pattern:
*Arithmetic means addition or subtraction*
To get from 8 to 14, we must add 6.
To get from 14 to 20, we must add 6.
The arithmetic pattern is 6.
List the rest of the terms (24 terms total):
8, 14, 20, 26, 32, 38, 44, 50, 56, 62, 68, 74, 80, 86, 92, 98, 104, 110, 116, 122, 128, 134, 140, 146
Formula:
Sn = n (a1 + an/2)
a1 = first term
an = last term
n = number of terms
Sn = 24 (8 + 146/2)
Sn = 24 (154/2)
Sn = 24 (77)
Sn = 1,848
Answer:
1848
Step-by-step explanation:
a=8
d=14-8=6
n=24
[tex]S_{n}=\frac{n}{2} [2a+(n-1)d]\\S_{24}=\frac{24}{2} [2 \times 8+(24-1)6]\\=12[16+138]\\=12 \times 154\\=1848[/tex]
