Answer:

i think it is the second one

Step-by-step explanation:

Exhaust all normal steps of factoring before deciding that you have a prime polynomial on your hands. Look for two numbers whose product is 8 and sum is 2. Check for the 2 and 4 when both are either plus or both are minus, for 8.

3/4 teaspoon water in each gallon. how much in 5 gallons

Vikentia [17]

We can solve this problem by applying the rule of three:

$\begin{gathered} \frac{3}{4}\text{ ------------ 1 gallon} \\ x\text{ ------------ 5 gallons} \end{gathered}$

then, x is given by

$x=\frac{(\frac{3}{4})(5)}{1}$

which gives

$\begin{gathered} x=(\frac{3}{4})(5) \\ x=\frac{15}{4} \end{gathered}$

that is, Pedro will mix 15/4 teaspoons on 5 gallons.

If we convert this result into a mixed fraction form, we obtain

$\frac{15}{4}=3\frac{3}{4}$

Answer:

1385.28 m²

Step-by-step explanation:

apothem = √16² - 8² = √256 - 64 = √192 = 13.86

Base area = 3 x 16 x 13.86 = 665.28

6 side area = 3 x 16 x 15 = 720

surface area = 665.28 + 720 =1385.28

Assuming that X is a binomial random variable with n = 10 and p = 0.25, find the probability, P for each of the following values

seropon [69]

Answer: a) 0.0584

b) 0.2816

c) 0.1877

d) 0.1877117

Step-by-step explanation:

The binomial probability formula :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials, n is total number of trials and p is probability of getting success in each trial.

Given : X is a binomial random variable with parameters :-

n = 10 and p = 0.25

$\text{a) P(x=5)}= ^{10}C_{5}(0.25)^5(0.75)^5\\\\=252(0.25)^5(0.75)^5\approx0.0584$

$\text{b) P(x=2)}= ^{10}C_{2}(0.25)^2(0.75)^8\\\\=45(0.25)^2(0.75)^8\approx0.2816$

$\text{c) P(x=1)}= ^{10}C_{1}(0.25)^1(0.75)^9\\\\=(10)(0.25)^1(0.75)^9\approx0.1877$

$\text{d) P(x=9)}= ^{10}C_{9}(0.25)^1(0.75)^9\\\\=(10)0.25)^1(0.75)^9\approx0.1877117$

A plant is 3 inches tall when you purchase it and grows 2 inches per month. Write an equation in slope intercept form that repre

tresset_1 [31]

Answer:

y = 3 + 2x

Step-by-step explanation:

In this scenario, we are given two values which are the initial height of the plant and its growth height. Then we are given a variable which is the number of months (x) that are unknown for us. The growth height needs to be multiplied by the number of months to know how much it has grown in that time period. Then we add this value to the initial height of the plant to calculate the total height (y) of the plant after x number of months. We can apply this information to form the following equation in slope-intercept form.

y = 3 + 2x
