Answer: (0,1/3)
Step-by-step explanation:
Answer:
The y-intercept of the function f(x) = -2/9x + 1/3 is 1/3.
Step-by-step explanation:
Given, function is
f(x) = -2/9x + 1/3.
The y-intercept is the point where the graph intersects the y-axis.
The y-intercept of a graph is (are) the point(s) where the graph intersects the y-axis.
We know that the x-coordinate of any point on the y-axis is 0.
So the x-coordinate of a y-intercept is 0.
To find the y - intercept set x = 0.
f(0) = (2/9 . 0) + 1/3
f(0) = 0 + 1/3
f(0) = 1/3.

What is linear pair?When two lines meet at a single point, a pair of linear angles is created. If the angles follow the point where the two lines cross, they are considered to be linear. A linear pair's angles add up to 180° in every case. These angles are additionally referred to as. A linear pair is made up of two angles that are next to one another and whose non-common sides form a line. All angles that create a linear pair are supplementary, however not all supplementary angles have to be linear pairs.In a linear pair, the total of two angles is always 180°. All neighboring angles are linear pairs, however not all adjacent angles are linear pairs.
∠DBA + ∠ABC = 180° ( ∵ linear pair)
∠100° + ∠ABC = 180°
∠ABC = 180° - 100°
∠ABC = 80°
The sum of angles of a triangle is 180° .
So, in triangle ABC
∠A + ∠B + ∠C = 180°
x + 80 + 60 = 180°
x + 140 = 180°
x = 180° - 140°
x = 40°
So, ∠A = x = 40°

Note that where the cylindrical and the cuboidal containers shown below have the same height. the same amount of water was poured into each container. The water filled 1/2 of the cylindrical container and 1/3 of the cuboidal container. If the base area of the cylindrical container is 154 sq cm, the base area of the Cuboidal Container is 15.2
What is the justification for the above?Let the height of the cylinder and cuboidal container be h m
We know that the base of the cylinder container is given as: 154 sq cm.
Recall that the volume for a cylinder is = Base x Height
That means in this case:
The volume for the cylinder is = 154 x Height
Thus,
1/2 * 154h = 1/3h³
77h = 1/3h³; divide both side by h to get
77 = 1/3h²
Collecting like terms and make h subject of the formula, we have;

If the mean time between unscheduled maintenance of LCD displays in a hospital's CT scan facility is 4,000 operating hours, what is the probability of unscheduled maintenance in exactly 5,000 hours?
The probability of unscheduled maintenance in exactly 5,000 hours is 4/5.
What is the probability?
We know that the probability deals with the fact that an event may or many not occur. It deals with a chance event. In this case, we have been told that the hospital's CT scan facility is 4,000 operating hours.
We know that the probability can be obtained from;
P = Number of unscheduled maintenance hours/Total operating hours
This would now give us that;
P = 4000/5000

Which of the arithmetic mean, median, mode, and geometric mean are resistant measures of central tendency?
a) The arithmetic mean and median only.
b) The median and mode only.
c) The mode and geometric mean only.
d) The arithmetic mean and mode only.
The median and mode only are resistant measures of central tendency.
The correct option is B.
Statistics that are resistant to outliers don't change as a result. We assert that the median is a resistive measure of centre, in contrast to the mean, which is not. In a way, the median is able to reject distant values whereas the mean is drawn to them. It cannot withstand the impact of excessive values. The measurement that is least subject to sample variation is the median, which is defined as the middle of ranking data, where 50% of values are above it and 50% below it. As a result, the extreme figures have no bearing on the median. For symmetric data, nonresistant measures perform better because they are less affected by skewness and outliers. Resistant measures can be used since they are less negatively influenced.

How to solve the percentage in pie chart?Pie charts are a great way to visualize data and percentages. To solve the percentage in a pie chart, you must first identify the total amount represented by the pie chart. Then, divide the value of each section of the pie chart by the total amount and multiply the result by 100 to calculate the percentage of the total that each section represents. For example, if a pie chart has 3 sections with values of 15, 25, and 60, the total would be 100. Then, 15 divided by 100 is 0.15, or 15%, 25 divided by 100 is 0.25, or 25%, and 60 divided by 100 is 0.6, or 60%.

how much will she make on $480 in sales?
The commission made by Jill for a $480 sale at the rate of commission 30% is $144.
What is meant by the rate of commission?
A commission is a payment made to a salesperson by a company in exchange for his or her assistance in facilitating or closing a sale. The design of the underlying commission agreement determines how a sales commission is calculated.
The rate of commission is a percentage or fixed sum that is linked to a specific amount of sales.
Given,
Sales = $300
Commission = $90
Then, rate of commission = (Commission/ sales) * 100
= ( 90/300) * 100 = 30%
For this rate of commission, the commission she makes for a $480 sale is

In the diagram below, m is the perpendicular bisector of BC.
If BK = 5x, AC = 6x + 7, CP = 4x, AB = 9x – 14. Find BC
Answer:
BC = 56 units
Step-by-step explanation:
since the main diagonal AK bisects the diagonal BC , then the figure is a kite.
• the disjoint pairs of consecutive sides are congruent in a kite, that is
AB = AC and BK = CK
using the pair AB = AC to solve for x
9x - 14 = 6x + 7 ( subtract 6x from both sides )
3x - 14 = 7 ( add 14 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Since m bisects BC , then
CP = PB and
BC = CP + PB = 4x + 4x = 8x
then
BC = 8x = 8 × 7 = 56
