Answer:

Step-by-step explanation:

If 3m + 5 = 8

We can say 8 - 5 = 3m

So, 3 = 3m

So, m = 1.

1 x 3 = 3!

Answer:

m = 1

Step-by-step explanation:

Plus -5 to both sides of the problem

5+-5+3 m=8+-5

Put together the alike terms

0+3 m=8+-5

3 m=8+-5

Put together the alike terms again

3 m = 3

Divide the sides by 3 then simplify and BAM! Answered. :P

HELP ME (How many cubes with side length 1/2 cm does it take to fill the prism

Natalija [7]

answer:

step-by-step explanation:

for this you would find the volume and then divide by 1/2

v = l x w x h

v = (1)(2)(3/2)

v = 3

now, divide

3 ÷ 1/2 = 6

therefore, it will take 6 half cubes to fill up the container

A genetic experiment with peas resulted in one sample of offspring that consisted of 414 green peas and 154 yellow peas. a. Cons

alekssr [168]

Answer: a. The interval in percentage is (23.46% , 30.76%)

b. No

Step-by-step explanation: To determine the confidence interval of a proportion, first find the percentage of yellow in that population:

phat = $\frac{154}{414+154}$

phat = 0.2711

The level α is 95%

1 - α = 0.05

α/2 = 0.025

As the population is bigger than 30, use z-test.

According to the table, z-score for α/2 = 0.025 is z = 1.96

The error for the interval is:

E = z. $\sqrt{\frac{phat(1-phat)}{n} }$

E = 1.96. $\sqrt{\frac{0.2711(1-0.2711)}{568} }$

E = 1.96*0.01865

E = 0.0365

The lower and higher limits of the interval are:

phat - E = 0.2711 - 0.0365 = 23.46%

phat + E = 0.2711 + 0.0365 = 30.76%

In conclusion, the 95% confidence interval to estimate the percentage of yellow is (23.46%,30.76%)

b. No, because 25% is inside the interval meaning that it doesn't contradict the expectations.
