Answer:
89
Step-by-step explanation:
3 consecutive numbers can be:
[tex]x-1, x, x+1[/tex] ; for example: 1, 2, 3 (1 is 1 less than 2, and 3 is 1 more than 2)
The sum is all of them added, so
[tex]x-1+x+x+1=270; 3x=270; x=90[/tex]
90 is the middle number though, so the first number is 89

Answer:
62
Step-by-step explanation:
surface area of a rectangular prism = 2lw + 2lh + 2wh
Where l = length, w = width and h = height
The box has the following dimensions
length = 5 in
width = 3 in
height 2 in
Using these dimensions, we plug in the values into the formula
[tex]SA=2(5*3)+2(5*2)+2(3*2)\\5*3=15\\15*2=30\\5*2=10\\10*2=20\\3*2=6\\6*2=12\\SA=30+20+12\\30+20+12=62[/tex]
Hence, the surface area = 62
How much money would you have in an account after 15 years if you earned 9,3% annually and you started with R573,00?
Given:
Principal = R573.00
Rate of interest = 9.3% annually
Time = 15 years.
To find:
The amount after 15 years.
Solution:
Formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest in decimal, n is the number of time interest compounded in an year and t be the number of years.
The interest is compounded annually, so n=1.
Putting [tex]P=573,r=0.093,n=1,t=15[/tex] in the above formula, we get
[tex]A=573\left(1+\dfrac{0.093}{1}\right)^{1(15)}[/tex]
[tex]A=573\left(1+0.093\right)^{15}[/tex]
[tex]A=573\left(1.093\right)^{15}[/tex]
[tex]A=2174.98893[/tex]
[tex]A\approx 2174.99[/tex]
Therefore, the amount in the account after 15 years is about R2174.99.

g The least-squares regression line of the number of visitors, y, at a national park and the temperature, x, is modeled by the equation . What is the predicted number of visitors when the temperature is 78o? 10.3 visitors 85.2 visitors 95.5 visitors 888.6 visitors 6,655.9 visitors
Answer: D) 888.6
Step-by-step explanation:
The expression which would help arrive at the required answer is y = 78b + c.
The least regression equation is the equation of best fit obtained from a linear regression graph.
The linear regression equation is expressed in the form :
y = bx + c ; where ;
y = Predicted variable
x = predictor variable
c = intercept
b = slope
The least regression equation is not given in the question above.
However, we could give the equation in the linear regression format :
y = number of visitors
y = number of visitors x = temperature = 78°
Hence, the equation becomes :
y = b(78) + c
y = 78b + c
Inputting the values of b and c in the equation will give the required answer.
