Answer:
(a) z(105)= (105-95)/10
= 1
z(85)= (85-95)/10
= -1
P(85< x < 105) = P(-1< z < 1) = 0.6825
Quantity of people of 1600 that have IQ between 85 and 115 = 0.6825*1600= 1092
(b) z(105) = (115-95)/10 = 2
z(85) = (75-95)/10 = -2
P(-2< z < 2) = 0.6827
quantity of people of 1600 that have IQ between 75 and 115 = 0.6825x1600=1092
(c) Z(>125)=( 125-100)/10=3

caterpillar crawls 25 inches in one minute. How many inches does it crawl in 5 minutes?
Answers
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

Answer:
x = 35
Step-by-step explanation:
Co interior angle sum to 180° , so
x + 30 + 3x + 10 = 180 , that is
4x + 40 = 180 ( subtract 40 from both sides )
4x = 140 ( divide both sides by 4 )
x = 35

The second term of arithematic proggresions 7. and the sum of the first four termd is 12 find
a) first term
b)common difference
Answers
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

C. the total amount of earned salary or wages.
D. the total amount an employer withholds for taxes.
Answers
Gross income is: The total amount of earned salary or wages. Option C is the correct answer.
Gross income refers to the total amount of money earned by an individual before any deductions or taxes are taken out. It represents the complete earnings from employment or other sources of income before any adjustments or deductions are made.
Gross income includes the full amount of salary or wages earned by an individual, as well as any additional income such as bonuses, commissions, or tips.
Option A is incorrect because gross income is the total amount earned before tax and benefit deductions are applied.
Option B is incorrect because gross income is not after tax, but rather before any tax deductions.
Option D is incorrect because gross income does not specifically refer to the amount withheld for taxes, but rather the total amount earned before any deductions.

prince covers 1200 meter distance in 10 minutes . calculate his velocity
Answers
Answer: 120 m/min or 2 m/s
Concept:
Here, we need to know how to calculate velocity.
Velocity = ΔD / ΔT
The SI unit of velocity is m/s
Solve:
Given information
Distance = 1200 m
Time = 10 min
Given expression
Velocity = ΔD / ΔT
Substitute values into the expression
Velocity = 1200 / 10
Velocity = 120 m/min
Extra:
**Disclaimer** Ignore this part if it is irrelevant to what you are learning.
If the question needs an answer with SI unit, then please see below:
Given information
Distance = 1200 m
Time = 10 min = 10 × 60 = 600 sec
Given expression
Velocity = ΔD / ΔT
Substitute values into the expression
Velocity = 1200 / 600
Velocity = 2 m/s
