To solve both it is (1,1). I'm not sure how to write the answer in y=mx+b format, but I made a graph using desmos.com if that helps.

Nadusha1986 [10]

Answer:

Domain[0, ∞). Range (-∞,4).

Step-by-step explanation:

domain is your lowest x (zero) to your highest x (infinity)

range is the lowest y (negative infinity) to your highest y (four)

What are the next three terms 4, 7/4,-1/2,-11/4...

Molodets [167]

Answer:

{-29/4, -19/2, -47/4}

Step-by-step explanation:

Note that this is a decreasing arith. seq. Each term is smaller than the previous term, the result of the subtraction of 2 1/4 (equivalent to 9/4).

The fourth term is -11/4; subtracting 9/4 results in -20/4, or -5.

The fifth term is -20/4; subtracting 9/4 results in -29/4.

The 6th term is -29/4; subtracting 9/4 results in -38/4, or -19/2.

The 7th term is -38/4; subtracting 9/4 results in -47/4.

Thus, the "next three terms" following the first four terms are {-29/4, -19/2, -47/4}

When a truckload of apples arrives at a packing plant, a random sample of 150 is selected and examined for bruises, discoloratio

myrzilka [38]

Answer:

c. 0.088

Step-by-step explanation:

Let p(s) be the proportion of apples defected in the sample. The probability that p(s)<0.05 can be calculated by calculating z statistic of 0.05:

$\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } }$ where

p(s) = 0.05

p is the proportion of the apples in fact defected (0.08)

N is the sample size (150) Then,

z(0.05)= $\frac{0.05-0.08}{\sqrt{\frac{0.08*0.92)}{150} } }=-1.354$

And P(z<-1.354)≈0.0879

Therefore the probability that a random sample of 150 among 8% defected apples can be accepted is 0.088.

PLEASE HELP, BEST ANSWER GETS BRAINIEST Each letter of the word "RESPONSIBLE" is written on a separate slip of paper and placed

Simora [160]

Answer:

1) 2/11

2) 2/121

Step-by-step explanation:

1. Because there are 2 E's, you have to chances out of your 11 changes, thus why the fraction 2/11 is the solution.

2. You know that 2/11 is the first fraction, so now find R. R has a 1/11 chance of getting chosen, so you multiply 2/11 and 1/11 to get 2/121.

The third term of the sequence is 120. The fifth term is 76.8 The explicit rule for the geometric sequence is an=?(?)n-1

gulaghasi [49]

Answer:

The explicit rule of the geometric sequence

aₙ = 187.5 (0.8)ⁿ⁻¹

Step-by-step explanation:

Step(i):-

Given that the third term of the sequence = 120

tₙ = a rⁿ⁻¹

t₃ = a r³⁻¹ = ar²

120 = ar² ..(i)

Given that the fifth term of the given geometric sequence = 76.8

tₙ = a rⁿ⁻¹

t₅ = a r⁵⁻¹ = a r⁴

76.8 = a r⁴...(ii)

Step(ii):-

Dividing (ii) and (i)

$\frac{ar^{4} }{ar^{2} } = \frac{76.8}{120}$

r² = 0.64

r =√ 0.64 = 0.8

Substitute r= 0.8 in equation (i)

120 = ar²

120 = a(0.8)²

⇒ $a = \frac{120}{0.64} =187.5$

Step(iii):-

The explicit rule of the geometric sequence

aₙ = a rⁿ⁻¹

put a= 187.5 and r = 0.8

aₙ = 187.5 (0.8)ⁿ⁻¹
