Answer:
5km/hr
Step-by-step explanation:
Given
Distance = 3km and 2km
Time = 30 mins, 15 mins, 15 mins
Required
Determine the average speed
To answer this, we need to determine the total distance.
Distance =3km + 2km = 5km
Then, we calculate the total time
Time = 30 mins + 15 mins + 15 mins = 1 hr
Next, we can now determine the average speed using:
Average Speed = Total Distance/Total Time
Average Speed = 5km/1 hr
Average Speed = 5km/hr

If Jackson turns on his favorite TV station at a randomly selected time, the probability that the current show will be on
a commercial break is 0.35.
Which of the following is the correct interpretation of this probability?
35% of the money that Jackson's favorite TV channel makes comes from advertising.
For every 100 minutes Jackson watches his favorite TV station, 35 of those minutes will be taken up by
commercials.
Tomorrow, Jackson's favorite TV station will run commercials for 35% of the air time.
If you take a very large sample of the times Jackson tunes in to his favorite TV station, a commercial will be on
about 35% of the time.
Answer:
D. If you take a very large sample of the times Jackson tunes in to his favorite TV station, a commercial will be on about 35% of the time.
This is the right answer

Find the length of the leg x. Enter the exact value, not a decimal approximation.
Answer:
x = 2√13.
Step-by-step explanation:
Using the Pythagoras theorem:
14^2 = x^2 + 12^2
x^2 = 14^2 - 12^2
x^2 = (14 + 12)(14 - 12) = 52
x = √52
x = √4*√13
x = 2√13.

5x + y = 7
20x + 2 = y
Answer:
x=0.2, y=6
Step-by-step explanation:
Since y=20x+2, 5x+y=7 => 5x + (20x +2 ) = 7
25x + 2 = 7
25x = 5
x = 0.2
so y = 20x + 2 = 20* 0.2 +2 = 4 + 2 = 6
so the final solution is [tex]\left \{ {{y=6} \atop {x=0.2}} \right.[/tex]
The values of x and y for the given simultaneous equation are;
x = 0.2 and y = 6
We are given 2 simultaneous equations;
5x + y = 7 ---(eq 1)
20x + 2 = y ----(eq 2)
Put 20x + 2 for y in eq 1;
5x + 20x + 2 = 7
25x + 2 = 7
25x = 7 - 2
25x = 5
x = 5/25
x = 0.2
Put 0.2 for x in eq 2 to get;
20(0.2) + 2 = y
4 + 2 = y
y = 6
In conclusion, the values of x and y are x = 0.2 and y = 6.

An AP is given by k,2k/3,k/3,0 .....Find the sixth term. find the nth term. If the 20th term is equal to 15, find k
9514 1404 393
Answer:
6th term: 8k/3n-th term: an = k + (k/3)(n -1)k = 45/22 for 20th term = 15Step-by-step explanation:
You know the general term of an AP is ...
an = a1 +d(n-1)
Here, a1 = k. The common difference is ...
2k/3 -k = -k/3
So, the general term is ...
an = k +(k/3)(n -1) . . . . the general term
__
The 6th term is then ...
a6 = k + (k/3)(6 -1) = (3k +5k)/3 = 8k/3 . . . . 6th term
__
The 20th term is ...
a20 = k + (k/3)(20 -1) = 22k/3
If this is 15, then the value of k is ...
22k/3 = 15
22k = 45
k = 45/22 . . . . value of k for a20 = 15

What is the product of 8.0 x 10^2 and 7.4 x 10^2 expressed in scientific notation?
Answer:
5.92 × 10^5
Step-by-step explanation:
8.0 × 10²= 800
7.4 × 10²= 740
800 × 740 = 592000
592000 in scientific notation looks like this 5.92 × 10^5
Hope this helps!!
Answer:
5.92 x 10^5
Step-by-step explanation:
The product of the two is 592000 and to do scientific notation you put the decimal after the first number and however many numbers are after that decimal is the number 10 is to the power of. To know if the exponent after the ten is positive or negative if you move the decimal to the right in order to make it the original number it is positive, and if you have to move it to the left then you have a negative exponent after the 10.

Step-by-step explanation:
Lupus is a medical phenomenon where antibodies that are supposed to attack foreign cells to prevent infections instead see plasma proteins as foreign bodies, leading to a high risk of blood clotting. It is believed that 2% of the population suffer from this disease. The test is 98% accurate if a person actually has the disease. The test is 74% accurate if a person does not have the disease.
If an individual tests positive for lupus, what is the probability that this is a false positive? (In other words, what is the probability of an individual not having lupus, given that they received a positive test result?)
Do not give your answer as a percentage chance, but rather as a decimal probability (i.e., 0.xxx).
Answer: the answer should be lower than because this is the percentage of people who get diagnosed with a disease that is not lupus 0.465 so about 50% or 0.5 hopefully that help I don't know the answer for the amount of people who don't have it and get misdiagnosed there is no information on it based on what I've seen

the mass of a block is 12g and the volume is 6 ml calculate the density of the block
a.) 0.5 g/ml
b.) 18 g/ml
c.)2 g/ml
d.)72g/ml
Answer:
c.)2 g/ml
Step-by-step explanation:
Given:
Mass of block = 12 g
Volume of block = 6 ml
Required:
Density of the block
SOLUTION:
Density is given as the mass of the block per unit volume.
Thus, density = mass/volume
Density of block = [tex] \frac{12 g}{6 ml} [/tex]
= 2 g/ml.
The answer is c. 2 g/ml.
