Answer 1

Answer: See explanation (btw, the answer is always in bold letters)

Step-by-step explanation:

1.) 1 gallon for $1.99

1/2 gallon for $0.98

1 gallon would be 0.98 × 2 = 1.96

2 gallons for $3.98

1 gallon would be 3.98 ÷ 2 = 1.99

2.) 621 ÷ 4 = 155.25

He pays $155.25 each payment!

3.) V = s³

s = 3

V = 3³

3 × 3 × 3 = 27

V = 27 m³

4.) This is a rectangle; the area of a rectangle is l × b.

L = 6.9

l × b = a

6.9b = 28.29

Divide both sides by 6.9

b = 4.1

The missing length is 4.1 m

5.) False

solve using elimination method. show work -3×+4y=1 -4×+5y=-2​

Answers

Answer:

Multiply the first equation by 4 and the second equation by -3:

-12x + 16y = 4

12x - 15y = -6

‣ Add the equations:

‣ Solve for y:

y = -2

‣ Substituting y = -2 into the first equation, we get:

-12x + 16 ⋅ (-2) = 4

‣ Solve for x:

x = -3

‣ Solution:

x = -3, y = -2)

The radius of a sphere is increasing at a rate of 2 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 40 mm

Answers

Answer:

[tex]\dfrac{dV}{dt}=502.65\ mm^3/s[/tex]

Step-by-step explanation:

The volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

The rate of change of volume means,

[tex]\dfrac{dV}{dt}=\dfrac{d}{dt}(\dfrac{4}{3}\pi r^3)\\\\\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3r\times \dfrac{dr}{dt}[/tex]

We have, [tex]\dfrac{dr}{dt}=2\ mm/s\ and\ r=40\ mm[/tex]

So,

[tex]\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3\times 20\times 2\\\\=502.65\ mm^3/s[/tex]

So, the volume is increasing at the rate of [tex]502.65\ mm^3/s[/tex].

-4n>24 write a answer as an inequality

Answers

Answer:

n < -6

Step-by-step explanation:

-4n>24

Divide each side by -4, remembering to flip the inequality

-4n/-4 < 24/-4

n < -6

Answer:

n < -6

Step-by-step explanation:

We are given the following equation and asked to solve for n:

-4n > 24

Divide both sides by -4 to isolate n by itself, and since we are dividing/multiplying a negative number on both sides, we need to flip the inequality sign:

(-4n)/-4 < 24/-4n < -6

In a certain country, the true probability of a baby being a boy is 0.519. Among the next nine randomly selected births
in the country, what is the probability that at least one of them is a girl?

Answers

Answer:

0.9973

Step-by-step explanation:

Given :

Probability of girl, probability of success , 1 - p = 1 - 0.519 = 0.481

1 - p = 0.481

n = 9

Probability that atleast one is girl

Usingbthe binomial probability distribution :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

USing the binomial probability calculator :

p(x ≥ 1) = p(x=1) + p(x=2) + p(x=3) + p(x=4) + p(x=5) + p(x=6) + p(x=7) + p(x=8) + p(x=9)

p(x ≥ 1) = 0.9973 ( from calculator).

Let's say we have a box with 6 marbles: 3 red, 1 blue, 1 green, and 1 yellow. What is the probability of picking a yellow marble, keep it, and then
picking a blue marble?

A 1/12
B 1/30
C 1/36
D 1/11


Answers

B. 1/30

Explanation: First you find the probability of picking a yellow marble, 1/6. Then you multiply the probability of picking a blue marble, 1/5 since there are now only five marbles total. Then multiply those to see what the final probability is, 1/6*1/5=1/30.
