15.4567.0787040.7872.0Step-by-step explanation:
Locate the digit to the right of the place you're rounding to. If that digit is 5 or more, add 1 to the digit in the place you're rounding to. Drop all digits to the right of the one you're rounding to, unless it is left of the decimal point. In that case, zero any digits between the one you rounded and the decimal point. (See problem 3 for an example of this.)
If you're rounding to the ones place (nearest whole number), and that digit ends up being 0, then put a decimal point after it to indicate it is a significant digit.

The value of a piece of land in a town is increasing every year . Its value, in dollars, t years after 1970 and until 2001 can be modeled by the function 31, 000(1.001) ^ t . What is the domain of the function ?
A. All whole numbers greater than or equal to 1971 and less than or equal to 2001 .
B. All real numbers greater than or equal to 1971 and less than or equal to 2001 .
C . All non - negative real numbers less than or equal to 31.
D. All whole numbers less than or equal to 31
Answer:
D. All whole numbers less than or equal to 31
Step-by-step explanation:
The x value in this situation is the number of years after 1970 and until 2001.
This means that the domain will be the number of years after 1970 and until 2001.
Since the situation calculates the value of land in years after 1970, the domain will start at 0. Since it is until 2001, which is 31 years after 1970, the domain will go up to 31.
So, the domain will include all whole numbers less than or equal to 31.
The correct answer is D. All whole numbers less than or equal to 31
The domain of the function is a real number from 1971 to 2001. Then the correct option is B.
What is an exponent?Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

How do I find the point of intersection?
Answer:
(-1 3/5, 2 3/5)
Step-by-step explanation:
Red Line:
m = 3-(-1)/-2-2 = 4/-4 = -1
b = 1
equation: y = -x + 1
Blue Line:
m = 5-1/2-(-4) = 4/6 = 2/3
find 'b':
5 = 2(2/3) + b
15/3 = 4/3 + b
b = 11/3
equation: y = 2/3x + 11/3
Find Point of Intersection:
-x + 1 = 2/3x + 11/3
multiply each side by 3 to get:
-3x + 3 = 2x + 11
-5x = 8
x = -8/5
find 'y':
y = -(-8/5) + 1
y = 8/5 + 1 = 13/5
y = 2 3/5
Explain how you will evaluate 4[ 3(62+1)] - 63
Answer:
693
Step-by-step explanation:
You can simply apply BODMAS(Bracket of Division Multiplication Addition Subtraction)
Here, the brackets come first
62+1=63
63*3=189
189*4=756
756-63=693
Answer:
720
Step-by-step explanation:
First you do the things inside the parenthesis which is 62 + 1 = 63
Which gives you this -----> 4[ 3 x 63]-36
Then do the brackets (brackets are these btw "[ ]" )
After doing the brackets you should bet this 4 x 189 - 36
Then you do the multiplication -----> 756 - 36
756 - 36 = 720

None of these
Answer:
Step-by-step explanation:
If the expression contains 3 terms none of which can combine with any other, the the expression is a Trinomial. An example of such a thing is f(x) = x^2 + 2x + 1.
The x cannot combine with the x^2 nor with the 1. The same can be said for the x^2 and the 1.

A random sample of size 32 is selected from population X, and a random sample of size 43 is selected from population Y. A 90 percent confidence interval to estimate the difference in means is given as (−1.25,0.87)
.
Consider a change in the sample sizes such that a random sample of size 52 is selected from population X and a random sample of size 63 is selected from population Y. When all other things remain the same, what effect would such a change have on the interval?
Answer:
The level of confidence will increase.
Step-by-step explanation:
Could be wrong
The change in the sample size will lead to a decrease in the width of the interval.
What is a sample size?A sample size simply means the number of subjects that are taken from the population for research.
In this case, increasing the sample size will decrease the standard error and therefore, the width of the confidence interval will reduce.
Therefore, as the sample size increases, the interval reduces.

Karina deposito S/. 3000 en un banco en un banco a una tasa de interes simple del 2% mensual ¿Cuánto ganara en dos años
Answer:
En dos años ganará S/. 4440.
Step-by-step explanation:
Puedes encontrar la respuesta utilizando la fórmula para calcular el valor futuro:
VF=VP*(1+(i*n))
VP= valor presente= 3000
i= tasa de interés= 0.02
n= número de periodos de tiempo= 24 meses (2 años corresponden a 24 meses)
VF=3000*(1+(0.02*24))
VF=3000*(1+0.48)
VF=3000*1.48
VF=4440
De acuerdo a esto, la respuesta es que en dos años ganará S/. 4440.
Suppose you are making a sail in the shape of a right triangle for a sailboat. The length of the longest side of the sail is 65 ft. The sail is to be 63 ft high. What is the length, in feet, of the third side of the sail?
Answer:
in right angled triangle ABC
hypotenuse [h]=65ft
base[b]=xft
height[p]=63ft
by using Pythagoras law
h²=p²+b²
65²=63²+x²
x²=65²-63²
x=√256
x=16feet
so the third side of the sail is 16ft.

Uptown Cable, a cable TV provider, charges each customer $120 for installation, plus $25 per month for cable programming. Uptown’s competitor, Downtown Cable, charges each customer $60 for installation, plus $35 per month for cable programming.

Answer:
B) Six Months.
Step-by-step explanation:
We can write an equation to model each situtation.
Let m be the number of months and c be its total cost.
Uptown Cable charges $120 for the initial installation fee plus $25 per month. In other words, its total cost is:
[tex]c=120+25m[/tex]
Downtown Cable charges an initial $60 fee plus $35 per month. So:
[tex]c=60+35m[/tex]
To find after how many months will the two services remain the same, we can set the two equations equal to each other and solve for m. So:
[tex]120+25m=60+35m[/tex]
Solve for m:
[tex]60=10m\Rightarrow m=6[/tex]
The two cable companies will charge the same after six months of use.
Notes:
If the customer uses the service for less than six months, then Downtown Cable is better since its initial cost is lower.
If the customer uses the service for more than six months, then Uptown Cable is better since its rate per month is lower.

what is hamids normal weight?
Answer:
8.8 kilograms
Step-by-step explanation:
Answer: 83.6 Kg
Step-by-step explanation:
x * 0.1 = y ---> x = y/0.1
88 - y = x
y/0.1 = 88 - y
2y = 88 * 0.1
