In FGH, what is the measure of H? 42° 43° 68° 69°

I need to find angle C, side length AB and side length AC

Kay [80]

For example, the same angles could give you a triangle with sides 7-12-13, 35-60-65, or any other multiple. Find the third angle by subtracting from 180°. Then use the Law of Sines (28)★ twice to find the second and third sides. Use the Law of Cosines (31)★ to find the third side.Feb 19, 2018

The data below indicate the contamination in parts per million in each of 50 samples of drinking water at a specific location.

Digiron [165]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Sorted data :

388, 389, 389, 390, 391, 393, 393, 393, 396, 398, 399, 400, 400, 400, 401, 402, 402, 403, 403, 403, 404, 404, 404, 405, 405, 405, 406, 406, 406, 407, 407, 408, 408, 408, 409, 409, 411, 412, 412, 413, 414, 416, 416, 416, 419, 420, 420, 424, 424, 1650

n = number of observations = 50

1) first quartile of the data (Q1) : 1/4(n+1)th term

1/4(51)th term= 12.75th term = 400

2)3rd quartile :

3/4(51)th term = 38.25th term = 412

3)median of data (Q2) :

1/2(51)th term = 25.5 th term = 405

4) mean of data

Σx / n = 21501 / 50 = 430.02

5)Outlier : Values that are greater than Q3 + 1.5 IQR or less than Q1 - 1.5 IQR

IQR = Q3 - Q1 = 412 - 400 = 12

> Q3 + 1.5 IQR

> 412 + 1.5(12) = > 430

< Q1 - 1.5 IQR = < 400 - 1.5(12) = 382

Outlier = 1650

Median after outlier is deleted :

1/2(50) th term = 25 th term = 405

Mean after outlier is deleted :

Σx / n = 19851 / 49 = 405.122

Two cars are 270 miles apart and travel toward each other on the same road. They meet in 3 hours. One car travels 2 mph faster t

Elza [17]

Answer:

B.44 mph and 46 mph

Step-by-step explanation:

This question is on relative speed

when cars move towards each other, you add their individual speeds to get their relative speed

Lets have two cars , A and B

Let car A to have an average speed of x m/h towards the right hand side

Let car B to have an average speed of x+2 m/h towards the opposite direction

The distance between the cars is 270 miles

Time of meeting is 3 hours

The relative speed will be x+x+2=2x+2 miles per hour

Apply the formula for time=Distance/speed =D/S

$t=\frac{D}{S} \\\\\\3=\frac{270}{2x+2} \\\\\\3(2x+2)=270\\\\\\6x+6=270\\\\\\6x=270-6\\\\\\6x=264\\\\\\x=\frac{264}{6} =44$

x=44 miles per hour

x+2=44+2=46 miles per hour

solution

44 mph and 46 mph

Kaci was trying to figure out how many pounds of Havarti cheese she could buy for $10, knowing that 3 pounds costs $7.50.

d1i1m1o1n [39]

Answer:

Step-by-step explanation:

First, find out how much one pound costs. 3 pounds costs $7.50, so divided 7.50 by 3.

7.50/3=2.50 So one pound costs $2.50. Now divide 10 by 2.50. 10/2.5=4

So Kaci can by 4 pounds of Havarti cheese for $10.
