Answer 1

Answer:

i think you have to multiply the sides..

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

1) PQ² + PR² = QR²

PQ² + 14² = 50²

PQ² + 196 = 2500

           PQ² = 2500 - 196 = 2304

            PQ = √2304

PQ = 48

Sin Q = [tex]\frac{opposite side}{hypotenuse}=\frac{14}{50}\\[/tex]

[tex]Cos Q = \frac{adjacent side}{hypotenuse}=\frac{48}{50}\\\\Tan Q = \frac{oppsite}{adjacent}=\frac{14}{48}\\\\\\\Sin R = \frac{48}{50}\\\\Cos R = \frac{14}{50}\\\\Tan R = \frac{48}{14}\\\\[/tex]

2) tan 48 = [tex]\frac{x}{17}[/tex]

x = 17 * tan 48  = 17 * 1.1106 = 18.8802

x = 18.8802

Which expression is equivalent to

Answers

Answer:

B) x^(5/3)*y^(1/3)

Step-by-step explanation:

Taking the cube root of a number is the same as raising it to the 1/3 power:

∛x=x^1/3

∛(x⁵y) = x^(5(1/3))*y^(1/3)=x^(5/3)*y^(1/3)

Remember to multiply exponents when raising an exponent to an exponent and distribute the 1/3 to each exponent!

A researcher wishes to estimate the proportion of college students who cheat on exams. A poll of 530 college students showed that ​21% of them​ had, or intended​ to, cheat on examinations. Find the​ 95% confidence interval for the population proportion. Round to four decimal places.

Answers

Answer:

(0.1753 ; 0.2447)

Step-by-step explanation:

Using the relation :

Confidence interval :

p ± margin of error

p = 0.21

1 - p = 0.79

n = 530

Zcritical at 95% confidence level = 1.96

Margin of Error : Zcritical * sqrt[(p(1-p))/n]

1.96 * sqrt[(0.21(0.79))/530]

1.96 * 0.0176923 = 0.0346769

Margin of Error = 0.0346769

Lower boundary = 0.21 - 0.0347 = 0.1753

Upper boundary = 0.21 + 0.0347 = 0.2447

Confidence interval :

(0.1753 ; 0.2447)

A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 15 cm long and 4 cm wide. The diameter of each circle is the width of the rectangle. What is the area of the bookmark? Use 3.14 for pi

Answers

Answer:

The area of the rectangle is Length x width. So 12x4 would =48 sq cm. The area of the circle is ( 3.14 ) x r2.

The area of the circle would be = (3.14)x2^2)=12.56 cm sq.

So the total  area is= Area of rectangle +Area of circle

TA=48+12.56

TA=60.56 sq cm

PLEASE HELP! Find the midpoint given (0,11) and (-6,3).

1. To determine if "A" students tend to sit in a particular part of the classroom, a teacher recorded the locations of the students who received grades of A. He found that 17 sat in front, 9 sat in the middle, and 5 sat in the back of the classroom, when testing the assumption that the "A" students are distributed evenly throughout the room, he obtained the test statistic of x2 = 7.226. If using a 0.05 significance level, is there sufficient evidence to support the claim that the"A" students are not evenly distributed throughout the classroom? Then state the conclusion.

find the equation of the line passing through points (-4,2) and (1,-6)

Answers

Answer:

y + 6 = (-8/5)(x - 1) in point-slope form

Step-by-step explanation:

Moving from the 1st point to the first, we see that x (the 'run') increases by 5 from -4 to 1, and y (the 'rise') decreases by 8.  Thus, the slope of the line through these two points is m = rise / run = -8/5

Now we have two points on the line, plus the slope.  Let's write out the point-slope formula for the equation of a straight line:

y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.

Here, using the point (1, -6), we obtain:

y + 6 = (-8/5)(x - 1) in point-slope form
