I don’t know if it’s g(2(5)(3(5)^2-5-5

Answers

Answer 1

Answer:

Answer:

B. 135

Step-by-step explanation:

For ...

f(x) = 3x^2 -x
g(x) = 2x -5

f(5) = 3·5^2 -5

= 3·25 -5 = 75 -5 = 70

Then g(f(5)) is ...

g(f(5)) = g(70) = 2·70 -5 = 140 -5

g(f(5)) = 135 . . . . . matches choice B

Rebecca Clarke's Nursery sells border plants for home gardeners at a discounted price of$12.99. Rebecca Clarke's has 335 plants it needs to sell. Fixed costs for all these plants were
$1,675 and variable costs per plant are $3.65. What is the maximum profit Rebecca Clarke's
will make if it sells all the plants at the discounted price?

Answers

Answer:

$1,540.70

Step-by-step explanation:

1675/335 = 5

3.65 * 335 = 1222.75

Cost of $8.65 per plant, or $2,897.75 for every plant.

12.99 - 8.65 = 4.34

Profit of $4.34 per plant, or $1,540.70 total.

The ellipse ^2/9 + ^2/4 =1, has its major axis length equal toa.13b. 9 c. 4 d. 3 e. 6

Answers

The given equation of ellipse is,

$\begin{gathered} (x^2)/(9)+(y^2)/(4)=1 \n (x^2)/(3^2)+(y^2)/(2^2)=1 \end{gathered}$

Thus, the major axis length can be determined as,

$2a=2*3=6$

Thus, option (e) is correct.

Answers

Answer:

1.896

Step-by-step explanation:

You can answer this just using your number sense.

$\log_7{(40)}\approx 1.896$

You know that 49 = 7², so log₇(49) = 2. The log function has a fairly small slope, so log₇(40) will not be far from 2.

_____

If you want to use your calculator, you can use the "change of base formula".

log₇(49) = log(49)/log(7) ≈ 1.602060/0.845098 ≈ 1.896

At a certain car dealership, 20% of customers who bought a new vehicle bought an SUV, and 3% of them bought a black SUV (that is 3% of customers bought a vehicle that was an SUV and in black color). Given that a customer bought an SUV, what is the probability that it was black?

Answers

Answer: 0.15

Step-by-step explanation:

As per given , the probability that customers who bought a new vehicle bought an SUV : P(SUV) = 0.20

The probability that customer bought a vehicle that was an SUV and in black color : P(SUV and black) =0.03

Now by suing conditional probability formula,

If we have given that a customer bought an SUV, then the probability that it was black will be :

$\text{P(Black}|\text{SUV})=\frac{\text{P(SUV and Black)}}{\text{P(SUV)}}$

$=(0.03)/(0.20)=(3)/(20)=0.15$

Hence, the required probability is 0.15.

The probability that a customer who bought an SUV also bought a black SUV is 0.006, or 0.6% (expressed as a percentage).

To find the probability that a customer who bought an SUV also bought a black SUV, you can use conditional probability.

Let's define the following events:

A: A customer bought an SUV.

B: A customer bought a black SUV.

You are given that P(B|A) is the probability that a customer who bought an SUV also bought a black SUV, which is 3% or 0.03.

You want to find P(B|A), the probability that a customer who bought an SUV also bought a black SUV. You can use the following formula for conditional probability:

P(B|A) = (P(A and B)) / P(A)

Here, P(A and B) is the probability that a customer bought both an SUV and a black SUV, and P(A) is the probability that a customer bought an SUV.

You know that P(B|A) = 0.03 and P(A) = 0.20.

Now, you need to find P(A and B), the probability that a customer bought both an SUV and a black SUV. You can rearrange the formula:

P(A and B) = P(B|A) * P(A)

P(A and B) = 0.03 * 0.20

P(A and B) = 0.006
