PLSSS HELP ME CORRECT ANSWER GETS BRAINLIEST

Mathematics
1 answer:
Alexxandr [17]3 years ago
7 0

Answer:

A is True

B is False

C is False

D is False

E is True

Lastly, F is False

Step-by-step explanation:

A would be= 71+27+50+50+50+48+48+47+47+45=518. Then you divide that by ten and you get 51.8

The mode is the most often reoccurring number We have 50 three times but 48 only twice.

The median is when you line all the numbers up in order and cross them out. It would look like this 71,57,50,50,50,48,48,47,47,45 however when y=we we cross the out we get both 50 and 48 in the middle when that happens we add them together and divide by two. That would get us 50+48=98/2=49 not 48

There are only two animals that can go faster than 50 mph ( The cheetah goes 57 mph and the Pronghorn antelope goes 57)

There are 7 animals faster than 47 mph so 7/10 as a percentage is 70%

The lowest and highest speed are 71 and 45 if we take those out we are left with 57+50+50+50+48+48+47+47 And that equals 49.625 which is lower than our old mean of 51.8

I hope this helps, have an amazing day!

Answer:

The equation of required line is: \mathbf{5x-8y+34=0}

Step-by-step explanation:

We need to write equation in the form Ax+By+C=0 of the line parallel to 5x-8y+12=0 and through the point (-2,3)

First we need to find slope and y-intercept of the required line.

Using equation of line  5x-8y+12=0 to find slope.

Since the given line and required lines are parallel there slope is same.

Writing equation in slope intercept form: y=mx+b where m is slope.

5x-8y+12=0 \\-8y=-5x-12\\\frac{-8y}{-8y}=\frac{-5x}{-8}-\frac{12}{-8}\\y=\frac{5}{8}x+\frac{3}{4}

So, the slope m = 5/8

The slope of required line is m=\frac{5}{8}

Now finding y-intercept using slope m=\frac{5}{8} and point(-2,3)

y=mx+b\\3=\frac{5}{8}(-2)+b\\3=\frac{-5}{4}+b\\b=3+\frac{5}{4}\\b=\frac{3*4+5}{4}\\b=\frac{12+5}{4}\\b=\frac{17}{4}

So, the equation of required line having slope m=\frac{5}{8}  and y-intercept b=\frac{17}{4}

y=mx+b\\y=\frac{5}{8}x+\frac{17}{4}\\y=\frac{5x+17*2}{8}\\y= \frac{5x+34}{8}  \\8y=5x+34\\5x-8y+34=0

So, The equation of required line is: \mathbf{5x-8y+34=0}

2. While on vacation, Erika's favorite activity is catching some rays while reading novels by the pool.
stiks02 [169]

Answer:

144 pages

Step-by-step explanation:

3 hours * 60 = 180 minutes

40 pages / 50 minutes = x pages / 180 minutes

40/50 = x/180

cross multiply

50x = 40 * 180

50x = 7200

x = 7200 ÷ 50

x = 144
