Answer:
f(2) =4, f(4) =4, x=8, x=3
Step-by-step explanation:
f(2) is asking for what the y value is when x is 2. f(4) is also asking what the y value is when x=4. When y=-2 the x is 8 and when the y=6 x=4. I hope this is helpful.
Answer:
There is a linear correlation between chest size and weight,0.8482
Step-by-step explanation:
Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.
the value of the linear correlation coefficient is r = 0.921.
i.e. there is a strong positive correlation from the value of r.
![H_0: r=0\\H_1: r\neq 0](https://tex.z-dn.net/?f=H_0%3A%20r%3D0%5C%5CH_1%3A%20r%5Cneq%200)
(Two tailed test at 5% level for correlation coefficient)
Test statistic t = ![\frac{r\sqrt{n-2 } }{\sqrt{1-r^2}} \\=5.791](https://tex.z-dn.net/?f=%5Cfrac%7Br%5Csqrt%7Bn-2%20%7D%20%7D%7B%5Csqrt%7B1-r%5E2%7D%7D%20%5C%5C%3D5.791)
p value <0.00001
Since p is less than 0.05 we reject H0
a) There is a linear correlation between chest size andweight
b)-- R^2 = 0.8482 proportion of the variation in weight can be explainedby the linear relationship between weight and chest size
Answer:
y = 23
Step-by-step explanation:
Assuming the equation not below is y = mx + b form...
m = 4
x = 3
b = 11
y = 4(3) + 11
y = 12+ 11
y = 23
Answer:
1-7 2-6 3-6 4-4
Step-by-step explanation:
To do this, you must notice that all of these are isosceles triangles (2 of the sides are the same.) You already have 1 value on each triangle, and the length of that side is the same length as the side with the unknown value, so those are the correct answers. If I made a mistake, please correct me. Everybody makes mistakes.
