Answer:
y = 1/4x -10
Step-by-step explanation:
The equation would be y = 1/4x -10
we know that we have to set the equation up as y=mx+b
m being slope and b being y-intercept
we can see on the graph that the line intercepts the y-axis at -10, so that would be b
for slope, you can just look and count rise over run so:
it goes 10 up and 40 over which equals 10/40 also known as 1/4
hope that helped :)
To start, this is an interest problem, meaning you will have to use I=prt where I is the total interest, p is the principle amount, r is the rate, and time is the amount of time in years. Since you know the principle rate is $1200, the rate is 3.9%, and the time is 8 months, you can plug this into the formula. However, keep in mind that you have to convert 3.9% to a decimal before putting it into the formula and the time must be represented in years. 3.9% represented as a decimal would be 0.039 and 8 months would be represented as 8/12 or 2/3 (since there are 12 months in one year). Now that you have this information, plug the values into the formula: i=(1200)(0.039)(2/3). When simplified, you get your answer as $31.20.
You can start by drawing a number line and labeling it with eighths. ( 1/8, 2/8, etc.) Then you can place a dot on 3/8 and 5/8. From there, it's clear to see that 5/8 is greater than 3/8.
Answer:
a) Robert, Juan, linda
b) Joel
c) Susan, Jan
d) 165.4
173.4
134.5
156
147.3
170.2
Step-by-step explanation:
The standardized normal distribution N (0,1) that expresion stands for normal distribution with mean 0 and standard deviation 1, therefore all positive values are above 0 and all negativa values are below 0
The sample n is 6 then we should use t-student distribution, we calculate t statistic as follow
t = (x-μ)/εε where standard error is εε = σ/√6 εε = 9.795 since σ =24
Robert
0.96 * 9.795 = x - 156 ⇒ x = 165.4
1.78 * 9.795 = x - 156 x = 173.4
-2.2 * 9.795 = x - 156 x = 134.5
0 * 9.795 = x- 156 x= 156
-0.89* 9.795 = x -156 x = 147.3
1.45 * 0.9795 = x -156 x = 170.2
