Express graph in slope intercept form
Answer:
2/6
Step-by-step explanation:
Count up and over going from one point to the next and you get slope intercept. This one is up 2 over 6
Answer:
y = 1/3x - 3
Step-by-step explanation:
Slope-intercept form follows the format y = mx + b, where m is the slope of the line, and b is the y-intercept.
First let's find the slope. The slope is the amount the graph rises/runs. From point (0,-3), it rises by 1, and runs to the right by 3 where it meets the next point on the graph, meaning that the slope is 1/3.
Now, let's find the y-intercept. The y-intercept is the point on the graph where the line touches the y-axis. In this line, we can clearly see that the line touches (0,-3), therefore, the y-intercept is -3.
Using this information, we can construct the equation y = 1/3x - 3
Find the length of AN given the figure below:
Answer:
21
Step-by-step explanation:
In the diagram, the three tangents (segment touching a circle at one point) have equal length.
6y - 3 = 29 - 2y
8y = 32
y = 4
Since the lengths of segments AM and AN are equivalent, we can substitute the value of y into the expression, 6y - 3, to find AN.
6y - 3 = 6*4 - 3 = 24 - 3 = 21

He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
He did not multiply the numerator and denominator by the correct number to equal 1,500.
His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion.
He can only solve the proportion by multiplying the numerator and denominator by a common multiple.
He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

Mr. jimenez deposited money into an account in which interest is compounded quarterly at a rate of 2.6%. how much did he deposit if the total amount in his account after 4 years was $7160.06, and he made no other deposits or withdrawals? $6455 $6455 $6798 $6798 $6887 $6887 $6977 $6977 skip to navigation
Answer:
$6455.
Step-by-step explanation:
The formula for this investment is:
A = P(1 + r/4)^4t where P = amount deposited , A amount after t years,
r = rate (as a decimal fraction).
So we have:
7160.06 = P(1 + 0.026/4)^16
7160.06 = P * 1.109227
P = 7160.06 / 1.109227
= $6455.

A shipment of inexpensive digital watches, including that are defective, is sent to a department store. The receiving department selects 10 at random for testing and rejects the whole shipment if 1 or more in the sample are found defective. What is the probability that the shipment will be rejected?.
0.8926 percent of the time, the shipment will be rejected.
What is Probability?The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
According to the given information:A delivery of 50 cheap digital watches, 10 of which are flawed.
A digital watch's likelihood of malfunctioning
P = 10/50
= 0.2
Size of sample: n = 10
Additionally, if they find one or more samples to be defective, they reject the entire cargo.
Making use of the binomial probability formula:
[tex]P(x)={ }^{n} C_{x} p^{x}(1-p)^{n-x}[/tex]
The random variable x should stand in for the quantity of defective watches.
The chance that the delivery will be refused is:
[tex]\begin{aligned}&P(x \geq 1)=1-P(0) \\&=1-{ }^{10} C_{0}(0.2)^{0}(0.8)^{10}\end{aligned}[/tex]
= 1 - (0.8)

A sector is said to be a part of a circle made of the arc of the circle along with its two radii.
The formula for calculating the area of a sector is expressed as;
A = r²β/2

Zoey read a novel in 30 days she made it a habit to read 13 pages everyday for the first 20 days. if in the last 10 days she reads 6 pages everyday how many pages are in the book?
Answer:
320 pages.
Step-by-step explanation:
We can simply multiply and add to find how many pages are in the book.
So we have (13 pg * 20 d) + (6 pg * 10 d) = 260 + 60 = 320.
Another way of solving is to set up a proportion for both the 20 and 10 days, find how many pages are read on these days, and add:
[tex]\frac{13pg}{1d}=\frac{xpg}{20d}\\ x=260pages\\\\\frac{6pg}{1d} =\frac{xpg}{10d}\\ x=60pg\\260+60=320[/tex]

a group of preschoolers has 2 boys and 30 girls. what os the ratio of boys to all childern
Answer:
1 boy to 15 girls.
Step-by-step explanation:
Since there is only two boys, I divided each number by two and got 1 to 15. Have an amazing day!
The ratio of boys to all children in the group is 1:16.
Given that in a group there are 2 boys and 30 girls.
We need to find the ratio of boys to all children.
To find the ratio of boys to all children in the group, we need to add the number of boys and girls together to get the total number of children.
Then, we can express the number of boys as a fraction of the total number of children.
Number of boys = 2
Number of girls = 30
Total number of children = Number of boys + Number of girls
Total number of children = 2 + 30 = 32
Now, we can express the number of boys as a fraction of the total number of children:
Ratio of boys to all children = Number of boys / Total number of children
Ratio of boys to all children = 2 / 32
To simplify the ratio, we can divide both the numerator and denominator by their greatest common divisor, which is 2:
Ratio of boys to all children = 1 / 16
So, the ratio of boys to all children in the group is 1:16.

In the regular octagon below, if AP = 12 cm. and BC = 19 cm, find its area.
First symmetrically cut the octagon to get 8 pieces. (So that you will get the idea that this polygon is divided into 8 triangles)
Then find the area of one of the triangles:
Area of Triangle = [tex]\frac{1}{2} * b* h[/tex]
A = [tex]\frac{1}{2}[/tex] × 12 × 19
A = 114 cm²
To find the area of the whole octagon shape:
A = 114 × 8 = 912 cm²
Hope it helps!
Answer:
Step-by-step explanation:
You cannot do this unless you are certain that P is the center of the octagon. I don't know if that's solvable from the information given. So I will make the assumption that P is the center.
Determine the midpoint of BC. Call it E. Draw a line from P to E. By symmetry EP = AP. BE = 1/2 * BC = 19/2 = 9.5 by construction
You have a trapezoid witch is 1/4 the area of the octagon. Three more trapezoids can fit into the octagon.
Formula
Area = (AP + BE)*PE / 2
Givens
AP = 12
BE = 9.5
PE = 12
Solution
Put the givens and constructions into the formula
Area = (12 + 9.5)*12/2
Area = 21.5 * 12/2
Area = 21.5 * 6
Area = 129
That's the area of one of the trapezoids. Multiply the area here by 4.
You get 516.

john is constructing a satellite dish . The receiver is going to be located 15 inches above the vertex of the dish. The dish is going to be 84 inches wide. How deep will the dish be
The depth of the 84 inches wide satellite dish that has the receiver located 15 inches above the vertex is 29.4 inches.
How can the equations of a parabola be used to find the depth of the dish?The location of the receiver = 15 inches above the vertex
Width of the dish = 84 inches
The receiver of a satellite dish is normally located at the focus (focal point).
Taking the shape of the satellite dish as a parabola, and writing the equation of the parabola as x² = 4•a•y, we have;
Coordinates of the focus = (0, a)
Where;
a = The distance of the focus above the vertex
Therefore;
a = 15 inches
The dish is horizontally spaced equally about the vertex.
The farthest point horizontally from the vertex, X, of the dish corresponds to the furthest vertically from the vertex, which is the maximum depth or height, Y.
At the maximum height, from the vertex, Y, (farthest point, vertically from the vertex), we have;
X = 84 ÷ 2 = 42
Which gives;
42² = 4 × 15 × Y
Y = 42² ÷ (4 × 15) = 29.4
