Answer:
The shopper can but 12 jackets.
Step-by-step explanation:
80*.6 (100% - 40% = paying 60% or .6) = 48
576 / 48 = 12
Here we have a problem of percentage discounts, such that we need to find how much a given price decreases, and how many jackets we can buy considering the decreased price.
We will find that the number is 12.
Now let's see how we can get that result:
If something has an original price P, and we discount an x% of that price, the new price will be:
[tex]np = P\cdot(1 - x\%/100\%)[/tex]
Here we know that the regular price of a jacket is $80
And we have a discount of 40%
This means that the new price of these jackets will be:
[tex]np = \$80\cdot (1 - 40\%/100\%) = \$80\cdot (1 - 0.4) = \$80\cdot 0.6 = \$48[/tex]
Now we want to know how many of these jackets we can buy with $576
This will be equal to the quotient between the money we have and the new price of each jacket:
[tex]N = \$576/\$48 = 12[/tex]
This means that we can buy exactly 12 jackets at the sale.

OA. 19,983
OB
8,504
C. 4,677
OD.
12,330
Answer: D. 12,330 phones
Step-by-step explanation:
First remove the fixed cost from the operating budget so that the variable cost that can be spent on each phone is known in total:
= 951,615 - 225,378
= $726,237
With each phone costing $58.90, the total number of phones that can be produced is therefore:
= Variable budget / Variable cost per phone
= 726,237 / 58.90
= 12,330 phones
Find sin(a) in the triangle.
Answer:
D. 20/29
Step-by-step explanation:
The sine of an angle in a right triangle is the ratio between the side opposite to the angle and the side adjacent to the angle, or [tex]sin(a) = \frac{opposite}{hypotenuse}[/tex]. The hypotenuse is the longest side of a right triangle.
In this case, the opposite side has length 20, and the hypotenuse has length 29. Therefore, the answer is
[tex]sin(a) = \frac{20}{29}[/tex].
To remember this (and the other trigonmetric ratios), you can use the acronym SOCAHTOA, where
SOH is sin(a) = opposite/hypotenuse
CAH is cos(a) = adjacent/hypotenuse
TOA is tan(a) = opposite/adjacent

Answer:
x = 250°
Step-by-step explanation:
"Angle formed between a chord and tangent intersecting on a circle measure the half of the intercepted arc"
From the figure attached,
Angle between the chord and the tangent = 55°
Measure of intercepted arc (minor arc AB) = h°
Therefore, 55° = [tex]\frac{1}{2}(h)[/tex]
[tex]h=110^0[/tex]
And m(minor arc AB) + m(major arc AB) = 360°
h° + x° = 360°
110° + x° = 360°
x° = 360° - 110°°
x = 250°
Therefore, measure of the intercepted arc is 250°.

Write an equation in slope-intercept form for the line perpendicular to y = -2x + 5 and containing the point (8,-3)
slope-intercept form of an equation for the line perpendicular to y = -2x + 5 is
y = 1/2x -7
What is perpendicular line?
The straight line that makes 90 degrees angle with a given line is called the perpendicular to the first line. The indicator of a line perpendicular to other line is the slope that is negative reciprocal to each other.
What is the equation of line perpendicular to the given line?
we know the slope intercept form of an equation of line is y = mx + b
m is the slope of line and b is the y intercept.
given, equation of a line, y = -2x+5
the slope m = -2 and y intercept, b = 5
we need to write an equation in slope-intercept form that perpendicular to the above line and containing the point (8, -3)
The required line of equation will have a slope equal to the negative reciprocal of the given slope.
hence, the slope will be m = 1/2
the equation of straight line will be y = 1/2x + b
as the line passes through the points (8, -3)
so, -3 = 1/2 × 8 + b
b = -7
y intercept of the new equation = -7
the new equation of line is y = 1/2x -7

As part of a study on pulse rates, a random sample of 10 study participants had their pulse rate taken and asked to sit quietly for 5 minutes. At the end of 5 minutes, their pulse rates were taken again. The mean difference between the two pulse rates for the 10 participants is -1.2 beats per minute with standard deviation of 2.97. Researchers are interested in estimating the mean difference in pulse rates before and after the 5 minute waiting period for the population of study participants. Calculate the 90% confidence interval for the mean difference in pulse rates for the population of study participants. Use t*
Answer:
The 90% confidence interval for the mean difference in pulse rates for the population of study participants is between -2.9 beats per minute and 0.5 beats per minute.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.8331
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.8331\frac{2.97}{\sqrt{10}} = 1.7[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is -1.2 - 1.7 = -2.9 beats per minute
The upper end of the interval is the sample mean added to M. So it is -1.2 + 1.7 = 0.5 beats per minute.
The 90% confidence interval for the mean difference in pulse rates for the population of study participants is between -2.9 beats per minute and 0.5 beats per minute.
What does the variable s equal in this equation?
S-10 = 31
Answer:
s = 41
Step-by-step explanation:
[tex]s - 10 = 31[/tex]
Add 10 to both the sides in order to isolate the variable 's'.[tex]=> s - 10 + 10 = 31 + 10[/tex]
