The data shows 68% percent of the area under the normal
distribution. This is equivalent to:
Answers
Answer: Plus or minus 1 standard deviation from the mean.
Step-by-step explanation:
According to the Empirical rule,
If the population is normally distributed then, about 68% of the population lies within 1 standard deviation from the mean value.
Here, the data shows 68% percent of the area under the normal distribution.
This is equivalent to "plus or minus 1 standard deviation from the mean."
Hence, the correct option is : plus or minus 1 standard deviation from the mean.

Examine rectangle JKLM, shown below.
If JN = x + 3 and JL = 3x + 1, determine which of the following values is correct
Answers
Answer:
NM = 8
Step-by-step explanation:
Given rectangle JKLM
JN = x + 3 and JL = 3x + 1
JN = 1/2JL as diagonals bisect each other and N is the midpoint of JL.
Substitute and solve for x:
x + 3 = 1/2(3x + 1)
2x + 6 = 3x + 1
3x - 2x = 6 - 1
x = 5
Find JN
JN = 5 + 3 = 8

which of these is the smallest number & which of these is the largest number
Answers
Answer:
A) D: 4.6
B) C: 5.12
Step-by-step explanation:
A) From the given options, the smallest number is 4.6 which is option D.
Due to the fact that the decimal sides from options A to the last are; 602, 620, 666..., 600.
This is because after the number 6, the remaining digits are assumed to be zero because there is no number attached again. The one that has 6 with dot above it means that it is a recurring decimal with 6. Thus, it can't be the smallest.
B) The largest is option C which is 5.12.
Because on the decimal sides, ranking from highest to lowest we have;
120, 111..., 102, 100. A number with dot on it means recurring decimal.

An initial population of 293 quail increases at an annual rate of 6%. Write an exponential
function to model the quail population. What will the approximate population be after 4 years?
Answers
Answer:
f(x)=293(1.06)^x;370
The quail population after 4 years is 370
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the factor.
Let y represent the population of the quail after x years.
There is an initial population of 293 quail, hence a = 293. the population increases at an annual rate of 6%. hence b = 100% + 6% = 1.06
The exponential function is given by:
y = 293(1.06)ˣ
The population after 4 years:
y = 293(1.06)⁴ = 370
The quail population after 4 years is 370

Ivanna deposits $500 into an account that pays simple interest at a rate of 6% per year. How much interest will she be paid in the first 2 years?
Answers
Answer:
$60 in interest
Step-by-step explanation:
To find interest, use the tried and true method of I = Prt (I is the interest, P is the principal, r is the rate, and t is the time (in years))
I = 500* 2 * 6% (What I do is go on and multiply the principal by the time)
I = 1,000 * 6% (Now to convert 6% and 1,000 into fractions)
I = 1,000/1 * 3/50 (Cross-cancel if needed here; The GCF of 50 and 1,000 is 50)
I = 20/1 * 3/1 (Just remove the /1 part here, they're wholes!)
I = 20 * 3 (Multiply and you have your answer!)
I = $60
Answer:
Ivanna after 2 years of 6% intrest will have 561.8 $ in her accout.
Step-by-step explanation:
500 times 6% can be done like 500 x 0.06 which is 30. So 530. Then 530 time the 6% which is 530 x 0.06 is 31.8. So 530 + 31.8 = 561.8$

Answers
0.373 seconds. First, calculate the initial vertical velocity of the shell. 800sin(30) = 800*0.5 = 400 m/s Now the formula for the distance traveled is d = 400 m/s * T + 0.5A T^2 Substituting known values gives. 150 = 400 m/s * T + 0.5*9.80m/s^2 T^2 150 = 400 m/s * T + 4.9 m/s^2 T^2 Arrange as a quadratic formula 0 = 400 m/s * T + 4.9 m/s^2 T^2 - 150 4.9 m/s^2 T^2 + 400 m/s * T - 150 = 0 Now solve for T using the quadratic formula with a=4.9, b=400, and c=-150 The calculated value is 0.373 seconds. Is this value reasonable? Let's check. The initial downward velocity is 400 m/s. So 150/400 = 0.375 seconds. Since the actual time will be a bit less due to acceleration by gravity and since the total time is so short, there won't be much acceleration due to gravity, the value of 0.373 is quite reasonable.

Write the equation of a line that is perpendicular to the equation y=-x+4 and passes through the point (2,5)
Answers
Answer:
y=x+3
Step-by-step explanation:
perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.
here is the equation: y=-x+4
the slope is -1
here is the equation to find the slope of the perpendicular line:
-1m=-1
multiply by -1
m=1
here is the new line so far: y=1x+b
now, we can substitute the point (2,5) into the equation, since the equation will pass through that point to find b (the y intercept)
5=1(2)+b
5=2+b
3=b
the equation of the line is y=1x+3, or y=x+3

Step-by-step explanation:
(0,-6) and (0,3) because the x intercept is when y=0 and if you want y to equal 0 one of the 2 parenthesis's values should equal 0 there are 2 answers because even if one of the parenthesis equals 0 the other one that is multiplied by it no matter what the value of that is equals 0. For example take (x+3)(x-4) one way to make this 0 would be for x to equal -3 or +4.
