<u>Answer</u>

<u>Right Scalene Triangle</u>

Side a (X) = 14.91038 (To the nearest hundreth: 14.91)

Side b = 7

Side c = 13.16509

Angle ∠A = 90° = 1.5708 rad = π/2

Angle ∠B = 28° = 0.48869 rad

Angle ∠C = 62° = 1.0821 rad

Calculations:

alculated based on 2 given angles and 1 given side.

∠C = 180° - A - B = 1.0821 rad = 62°

a = b·sin(A)/sin(B) = 14.91038

c = b·sin(C)/sin(B) = 13.16509

Area =

ab·sin(C)

= 46.0778

Perimeter p = a + b + c = 35.07547

Semiperimeter s =

a + b +c

= 17.53773

Height ha =

2×Area

= 6.18063

Height hb =

2×Area

= 13.16509

Height hc =

2×Area

= 7

Median ma = √(a/2)2 + c2 - ac·cos(B) = 7.45519

Median mb = √(b/2)2 + a2 - ab·cos(C) = 13.62239

Median mc = √(c/2)2 + b2 - bc·cos(A) = 9.60884

Inradius r =

Area

= 2.62735

Circumradius R =

2sin(A)

= 7.45519

Sixteen college freshmen were asked to record the number of alcoholic drinks they typically consume in a week. Here are their da

rjkz [21]

Solution: The correct option is d. 8.75

<u>Explanation:</u>

The formula for variance is:

$Variance =\frac{\sum(x-\bar{x})^{2}}{n}$

First we need to find the mean $\bar{x}$ of the given data:

$\bar{x}=\frac{2+4+6+0+1+10+9+0+6+3+6+8+5+4+6+2}{16}=\frac{72}{16} =4.5$

Now let's find $\sum(x-\bar{x})^{2}$ , please have a look at the attached picture:

$\therefore Variance = \frac{140}{16}=8.75$

Easy brainliest for correct answer 100%

MakcuM [25]

Answer:

B) A/l

Step-by-step explanation:

Isolate the variable, w. Note the equal sign, what you do to one side, you do to the other.

Divide l from both sides of the equation:

A = l * w

(A)/l = (l)/l * w

w = A/l

B) A/l is your answer.

Which graph best represents the equation created when the slope of y = 6x is changed to 0?

luda_lava [24]

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

<h3>What is a linear function?</h3>

A linear function is in the form:

y = mx + b

Where m is the slope (rate of change) and b is the y intercept

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

Sidney skated for 1 1/10 hours last month and 8 7/10 hours this month. How many

olganol [36]

Answer:

the number of hours does sidney skate in all is 9.8 hours

Step-by-step explanation:

The computation of the number of hours does sidney skate in all is as follows:

= Last month + this month

$= 1 \frac{1}{10} + 8 \frac{7}{10}\\\\= \frac{11}{10} + \frac{87}{10}\\\\= \frac{98}{10}$

= 9.8 hours

Hence, the number of hours does sidney skate in all is 9.8 hours
