The three angles in a triangle are in the ratio 3:5:7. Find the largest angle in the triangle?
Rzqust [24]

Answer: The largest angle is 7x

Step-by-step explanation:

Their sum is 180, so

3x + 5x + 7x = 180

5x = 180 --> x = 12

The largest angle is 7x, which is 7(12) = 84

Write an equation that is perpendicular to y=3/5x-1 and passes through the point (9,14)
Leokris [45]

Answer:

y=(-5/3)x+29

Step-by-step explanation:

we will use the base formula y=mx+b

In order to be perpendicular, the slope must be the flipped fraction and have the opposite sign, so our m is (-5/3)

y=(-5/3)x+b

You can plug in the (9,14) point in order to find the b

14=(-5/3)(9)+b

14=(-45/3)+b

14=(-15)+b

14+15=b

29=b

and so altogether our equation is y=(-5/3)x+29

A. you plug in to a calculator, which will give 1840.986 so you need to round up to 1840.99. if you truncate it to .98 then he won't reach 2000 in 3 years

b. for this one if you look at the equation given to find the principle it is principle = result (1+rate) ^ -time

if you re arrange this you get result=principle (1+rate)^time
so result = 1840.99(1.028)^5
= 2113.57

According to a recent article the average number of babies born with significant hearing loss (deafness) is approximately two pe
Leviafan [203]

Answer:

0.27

Step-by-step explanation:

The probability P that exactly two babies were born deaf can be gotten by the binomial distribution as

P = {n\choose k} \, p^k \,(1-p)^{n-k}


where n is the sample size (the number of babies  randomly surveyed), k is the number of success, i. e., the baby is deaf; and p is the probability of selecting a deaf baby = 2/1000 = 0.002. Therefore

P = {1000\choose 2}\, 0.002^2\, (1-0.002)^{1000-2}


P = 0.27
