Answer:

$y \leqslant 6$

Step-by-step explanation:

The range is set of all y-values. The range starts from minimum value to maximum value.

We don't have minimum value (approaching negative infinity.)

We have maximum value at x ≈ 2 equal 6.

Therefore the answer is

-inf <= y <= 6. But we don't usually write that. Instead, we cut out -inf and we get —

$y \leqslant 6$

Since the word, 'of' means to multiply, whenever we see of multply the two numbers.
Then there are two ways to dothis, sicne to convert a percentage into a decimal, you devide by 100, we can either do this after we multiply or bfore, it doesn't matter so I'm going to do it after.

1. 520x100=52000/100=520
2. 20.25x3=60.75/100=.6075
3. .15x250=37.5/100=.375
4. 200x79=15800/100=158
5..3x80=24/100=.24
6. .28x50=14/100=.14

WILL GIVE BRAINLIEST find the value of r (-4,8), (r,12), m=4/3 (show your work pls)

OLEGan [10]

Answer:

r = 13

Step-by-step explanation:

The first step is to find b from y=mx=b using m=4/3 and (-4,8)

$8=\frac{4}{3}(-4)+b$

After solving the equation, b will equal -16/3 making the final equation be

$y=\frac{4}{3} x-\frac{16}{3}$

Using the equation, you can solve for r.

$12=\frac{4}{3} x-\frac{16}{3}$

This will bring the answer being r = 13

Suppose that 70% of all Americans agree that a candidate is not trustworthy. A survey finds the 116 out of 200 agree that a cand

MArishka [77]

Answer:

Prob = 0.00009 = 0.009% , Less Likely

Step-by-step explanation:

Using Binomial Distribution, Prob = N c r . ( P )^ r . ( Q ) ^ (n -r) .

,P = success probability, ie candidate considered be trustworthy = 70% = 0.7; N = trials = 200 ; Q = failure probability, ie non trustworthy = 1 - 0.7 = 0.3 r = no. of success = 116

Pr = 200c116 . (0.7)^116 . (0.3)^(200 - 116) = 200c116 (0.7)^116 (0.3)^84 = 0.00009 = 0.009%

Less probability means Less Likely
