In March for every 2 days it rained out of 5 days. A total of 30 days were calculated, How many days did it rain?

Did I do it right? If the measure of ∠DAB=51∘, ∠CAB=x, and ∠DAC=x+1, find the measure of ∠CAB

aliya0001 [1]

If the measure of angles ∠DAB = 51° and the value of x is 25. Then the measure of angle ∠CAB will be 25°.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

If the measure of angles ∠DAB = 51°, ∠CAB = x, and ∠DAC = x + 1.

Then the measure of angle ∠CAB will be

We know

∠CAB + ∠CAD = ∠DAB

x + x + 1 = 51

2x = 50

x = 25

Then the measure of the angle ∠CAB will be

∠CAB = x

∠CAB = 25

∠CAB = 25°

What is 1/8 divided by 1/2

vladimir1956 [14]

1/8÷1/2
You flip the second one and change it to multiplication:
1/8×2/1=2/8
2/8 can be simplified by dividing both sides by 2:
1/4

Hope this helps :)

A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t

Thepotemich [5.8K]

Answer:

The probability that exactly 12 buyers would prefer green

=0.00555

Step-by-step explanation:

We are given that

p=50%=50/100=0.50

n=14

We have to find the probability that exactly 12 buyers would prefer green.

q=1-p

q=1-0.50=0.50

Using binomial distribution formula

$P(X=x)=nC_r p^r q^{n-r}$

$P(x=12)=14C_{12}(0.50)^{12}(0.50)^{14-12}$

$P(x=12)=14C_{12}(0.50)^{12}(0.50)^2$

$P(x=12)=14C_{12}(0.50)^{14}$

$P(x=12)=\frac{14!}{12!2!}(0.50)^{14}$

$P(x=12)=\frac{14\times 13\times 12!}{12!2\times 1}(0.50)^{14}$

$P(x=12)=91\cdot (0.50)^{14}$

$P(x=12)=0.00555$

Hence, the probability that exactly 12 buyers would prefer green

=0.00555

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm.

Vesnalui [34]

Answer:

After how many years is the fish population 100?

x=3.97 years

Step-by-step explanation:

The fish population increases by a factor of 1.5 each year. We have the equation that represents this situation

$f (x) = 20 (1.5) ^ x$

Where x represents the number of years elapsed f(x) represents the amount of fish.

Given this situation, the following question could be posed

After how many years is the fish population 100?

So we do $f (x) = 100$ and solve for the variable x

$100 = 20 (1.5) ^ x\\\\\frac{100}{20} = (1.5)^x\\\\ 5= (1.5)^x\\\\log_{1.5}(5) = log_{1.5}(1.5)^x\\\\log_{1.5}(5) = x\\\\x =log_{1.5}(5)\\\\x=3.97\ years$

Observe the solution in the attached graph
