Step-by-step explanation:
angle q and angle r are complementary. the measure of angle q is 26 degrees less than the measure of r. find the measure of each ang;e
Based on the definition of complementary angles, the measures are:
m<q = 32°
m<r = 58°
What are Complementary Angles?Tow angels are complementary if both angles give a sum of 90 degrees.
The sum of angle q and angle r would give 90 degrees because they are complementary angles. Therefore, we would have the following:
m<r = ?
m<q = m<r - 26
Plug in the values
m<r - 26 + m<r = 90
2(m<r) - 26 = 90
2(m<r) = 90 + 26
2(m<r) = 116
2(m<r)/2 = 116/2
m<r = 58°
m<q = m<r - 26 = 58 - 26
m<q = 32°
Therefore, based on the definition of complementary angles, the measures are:
m<q = 32°
m<r = 58°

Write the linear equation in slope-intercept form passing through the given points. (-12, 14) and (6, -1) (Hint: Start by finding slope between the two points, then put in point-slope form and then convert to slope-intercept form.) y= type your answer... X+ type your answer...
The slope-intercept form of the equation of the line described is y = -6x/5 + 32/5.
Given the following data:
Points on x-axis = (-12, 6).
Points on y-axis = (14, -1).
What is a slope?A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given points into the formula, we have;
Slope = (6 + 12)/-1 - 14)
Slope = -18/15
Slope = -6/5
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
x and y are the points.m represents the slope.c represents the intercept.At point (-12, 14), we have:
14 = -6/5(-12) + c
8 = 72/5 + c
40 = 72 + 5c
5c = 72 - 40
c = 32/5
In conclusion, we can reasonably and logically deduce that the slope-intercept form of the equation of the line described is y = -6x/5 + 32/5.

Let [tex]{ X_{i} }^{n} _{i = 1}[/tex] be a group of independent variables with Poisson distribution and the same distribution. Confidence intervals for can be created using a variety of methods, including the Wald method, precise inference, a variance stabilizing transformation, and many others. Actual and nominal coverage can differ significantly when n is small. For a Poisson mean, we compare nine confidence intervals in terms of coverage and expected width of the confidence bounds. We demonstrate that, for small n, only the exact interval maintains coverage probabilities; the scores interval maintains coverage probabilities roughly, but its expected width is greater than that of the exact interval.A modified confidence interval based on the variance stabilized confidence interval has coverage properties close to the nominal and an expected width that is not particularly large. Therefore, we advise using the exact interval for researchers who want real coverage that is at least nominal and a modified version of the variance stabilized interval for those who are OK with approximative coverage.

bus from 5:00 PM to 3:00 AM.
Each friend has agreed to chip in $12. One of the teachers at the high
school, Mr. Jones, has offered to chip in the rest. If he does, how much will
he pay
Answer:
$48
Step-by-step explanation:
The friends have the bus from 5:00 PM to 3:00 AM, so:
3 + 18 − 5 = 15 − 5 = 10 hours.
The cost of renting the bus will be:
$300 + $18 × 10 = $300 + $180 = $480.
The thirty-six students will contribute $12 each for a total of:
$12 × 36 = $432.
So Mr. Jones will pay:
$480 − $432 = $48.

Jerry is planting white daisies and red tulips in his garden and he wants to choose a pattern in which the tulips surround the daisies. He uses tiles to generate patterns starting with two rows of three daisies. He surrounds these daisies with a border of tulips. The design continues as shown.
a1mtxese346734a011006tai
Jerry writes the expression 8(b − 1) + 10 for the number of tulips in each border, wherein b is the border number and b ≥ 1. Complete the explanation to explain why Jerry's expression is correct.
For Border 1, tulips are added above and below the daisies, which gives a total of 6 tulips. A tulip is then added to the end of each row of daisies, which gives 4 tulips. So, there is a total of
tulips in Border 1.
For Border 2, there are
additional tulips added to the garden plus the 10 original tulips from Border 1.
8 + 10
For Border 3, there are
additional tulips added to the garden plus the 10 original tulips from Border 1 and 8 additional tulips from Border 2.
8(2) + 10
So, the expression for the number of tulips in the garden with Border b is .
In linear equation ,Jerry's expression is correct.
What in mathematics is a linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."As you can see, starting with border 1, we have 6 daises (white squares) surrounded by 10 tulips (colored squares). Through Jerry's expression we expected:
= 8(b − 1) + 10
= 8(1 − 1) + 10
= 0 + 10
= 10 tulips.
When considering border 2, we expect:
= 8(b − 1) + 10
= 8(2 − 1) + 10
= 8 + 10
= 18 tulips.
Indeed, we have the 10 tulips from border 1 and 8 additional tulips, for a total of 18 tulips.
Then, consider border 3, we expect:
= 8(b − 1) + 10
= 8(3 − 1) + 10
= 16 + 10
= 26 tulips.
Again, this is correct: we have the 10 tulips used in border 1 plus other 16 tulips, for a total of 26.
Therefore, Jerry's expression is correct.

Answer: 10x + 19 = 519 x = 50
Step-by-step explanation:
We are looking for the number of students that rode in each bus, so first lets subtract out those that drove in cars.
519-19=500
So 500 students rode on 10 buses. So now we divide the students onto the buses.

Each bus drove 50 students.
An equation to represent the total number of students as a function of those on the buses would be
