The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.

So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.

Answer:

The average of -2.5, 5.2, 1.7, and -0.8 is <u>0.9</u>

Step-by-step explanation:

You are taking the mean of all the values

So you would add -2.5, 5.2, 1.7, and -0.8 all together

This gives you 3.6

Then you would divide by the number of numbers per se,

Which would give you the answer: 0.9

(04.02 MC)
Elena L [17]

Answer:

0.1384

Step-by-step explanation:

Using binomial probability:

P = nCr p^r q^(n-r)

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1-p).

Given n = 25, r = 4, p = 0.10, and q = 0.90:

P = ₂₅C₄ (0.10)⁴ (0.90)²⁵⁻⁴

P = 12650 (0.10)⁴ (0.90)²¹

P = 0.1384

If F(x) =5x/3 +5
victus00 [196]

Answer:

f^{-1}(x)=\frac{3(x-5)}{5}

Step-by-step explanation:

f(x)=y=\frac{5x}{3}+5\\y-5=\frac{5x}{3}\\3(y-5)=5x\\x=\frac{3(y-5)}{5}\\ => f^{-1}(x)=\frac{3(x-5)}{5}

2/3 - 3/2y + 1/3y + 4 = 0​
Korvikt [17]

Answer:

y = 4

Step-by-step explanation:

(2/3 + 4) + (-3/2y + 1/3y) = 0

(-3/2y + 1/3y) = -4 2/3

-9/6y + 2/6y = -14/3

-7/6y = -14/3

cross-multiply:

-21y = -84

y = 4
