Answer:

38.5

Step-by-step explanation:

Lets say, first number = x



Second number = 3x+7



Total = 49




(x)+(3x+7)= 49



4x+7 = 49



4x = 42



x = 42/4



x= 10.5




x= 10.5



3x+7 = 3(10.5)+7 = 38.5




Hope this helps!!

\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}

Let's solve ~ ☂

\qquad \sf  \dashrightarrow \:  - 0.6(m + 1) = 3

\qquad \sf  \dashrightarrow \:  - (m + 1) = 3 \div 0.6

\qquad \sf  \dashrightarrow \:  - (m + 1) = 5

\qquad \sf  \dashrightarrow \:  - m  -  1= 5

\qquad \sf  \dashrightarrow \:  - m = 5 + 1

\qquad \sf  \dashrightarrow \:  - m =  6

\qquad \sf  \dashrightarrow \: m =  - 6

I hope it helps ~

A certain genetic condition affects 8% of the population in a city of 10,000. Suppose there is a test for the condition that has
enot [183]

Solution:

Population in the city= 10,000

As genetic condition affects 8% of the population.

8 % of 10,000

=\frac{8}{100}\times 10,000=800

As, it is also given that, there is an error rate of 1% for condition (i.e., 1% false negatives and 1% false positives).

So, 1% false negatives means out of 800 tested who are found affected , means there are chances that 1% who was found affected are not affected at all.

So, 1% of 800 =\frac{1}{100}\times 800=8

Also,  1% false positives means out of 10,000 tested,[10,000-800= 9200] who are found not affected , means there are chances that 1% who was found not affected can be affected also.

So, 1% of 9200 =\frac{1}{100}\times 9200=92

1. Has condition Does not have condition totals  = 800

2. Test positive =92

3. Test negative =8

4. Total =800 +92 +8=900

5. Probability (as a percentage) that a person has the condition if he or she tests positive= As 8% are found positive among 10,000 means 9200 are not found affected.But there are chances that out of 9200 , 1% may be affected

=\frac{\text{1 percent of 9200}}{9200}\\\\ \frac{\frac{1}{100}\times 9200}{9200}=\frac{92}{9200}\\\\ =0.01

that is Probability equal to 0.01 or 1%.

Name the solid and find its volume. Use 3.14 as the approximate value of pi.
sineoko [7]

It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .

The formula of volume of cone is

V = \frac{1}{3} \pi r^2 h

To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is

V = \frac{1}{3} *3.14*7^2 *16 = 820.6 \ units \ cube

And that's the required volume of the cone .
