The second term of arithematic proggresions 7. and the sum of the first four termd is 12 find
a) first term
b)common difference
Answer:
a) a1=15 first term
b) d=-8 common difference
Step-by-step explanation:
1)a1+d=7
2)a1+a2+a3+a4=12
a1+a1+d+a1+2d+a1+3d=12
4a1+6d=12
2a1+3d=6
We have the system of equations where a1+d=7 and 2a1+3d=6
3a1+3d=21
2a1+3d=6
Subtract the second equation from the first one
a1=15
d=-8
First term = 15
Common difference = -8
Let the first term be a and common difference be d.
Therefore,
a+d = 7 - eq. 1
a+(a+d)+(a+2d)+(a+3d) = 12 - eq. 2
4a + 6d = 12
4a + 4d + 2d = 12
Dividing both sides by 2,
2a + 2d + d = 6
2 (a+d) + d = 6
Substituting value of (a+d) in the above equation,
2*7 + d = 6
d = 6 - 14
d = -8
Substuting value of d in eq. 1
a+d = 7
a + (-8) = 7
a = 7 + 8
a = 15

Represent absolute value.
All absolute value means is the distance a number is from zero.
For example: -2 is 2 numbers away from zero.
5 is 5 numbers away from zero.
-7 is 7 numbers away from zero.
So when something says |-7| that is the same value as 7
So 7 = 7

caterpillar crawls 25 inches in one minute. How many inches does it crawl in 5 minutes?
Answer:
125 inches
Step-by-step explanation:
In one minute caterpillar crawls 25 inches. So in 5 minutes we have 5 times 25 inches is 125 inches.
By equation
Additional: 25 + 25 + 25 + 25 + 25 = 125 (inches)
Mutiplication: 25 * 5 = 125 (inches)
The caterpillar crawls 125 inches in 5 minutes
because it is said that the caterpillar crawls 25 inches in one minute so we can use multiplication 25 x 5 = 125

What is qualitative data?
Qualitative data tells about the quality or characteristic. It is tough to express it numerically or not at all expressible numerically. They are usually catagorical.
In contrast, there is quantitative data which can be expressed numerically.
Option A, Option B and Option D will get answers which would be in numbers. Thus, their responses would be quantitative.
Option C's question will get response as type of business that the business owners own. So its not in numbers and tells about the characteristic of businesses.
Thus, for the considered survey, the questions whose response is going to be qualitative is given by: Option C: "What type of business do you own?"
