1. Find the chi square value x 2 L corresponding to a sample size of 7 and a confidence level of 99%

sashaice [31]

Answer:

1. χ² = 18.548

2. χ² = 23.685

Step-by-step explanation:

1. Confidence level is 99% (α = 0.01), but we're only interested in the left half, so α/2 = 0.005. Degrees of freedom are 7−1 = 6. Looking up in a chi square table, χ² = 18.548.

2. Confidence level is 90% (α = 0.10), but we're only interested in the right half, so α/2 = 0.05. Degrees of freedom are 15−1 = 14. Looking up in a chi square table, χ² = 23.685.

If (9k, 7k) and (6k, 5k) are two points the graph if a line and k is not equal to 0 what is the sople of the line

olga_2 [115]

Answer:

The answer is 2/3

Step-by-step explanation:

In order to find the slope, we need to use the slope formula.

m (slope) = (y1 - y2)/(x1 - x2)

Now we can plug the points into the equation and solve.

m (slope) = (y1 - y2)/(x1 - x2)

m (slope) = (7k - 5k)/(9k - 6k)

m (slope) = 2k/3k

m (slope) = 2/3

Please help I dont know what to do!!!

Hey John

Let's start solving #1

x/4 = 3.5/28
Cross multiply
(x)(28) = (3.5)(4)
28x = 14
Divide both sides by 28
28x/28 = 14/28
x = 1/2

Next, let's solve the second one

$\frac{3}{5} + \frac{4}{5x} + \frac{7}{10x} + 1 \frac{1}{2} = 5 \frac{3}{5}$
Simplifies to:
$\frac{105x+75}{50x} = \frac{28}{5}$
Cross multiply
(105x + 75)(5) = (28)(50x)
525x + 375 = 1400x
Subtract 1400x to both sides
525x + 375 - 1400x = 1400x - 1400x
-875x + 375 = 0
Then subtract 375 from both sides
-875x + 375 - 375 = 0 - 375
-875x = -375
To find x, divide both sides by -875
-875x/-875 = -375/-875
x = 3/7

Let me know if you have questions about the answer.

Best of luck with your studies!

Solve using the Pythagorean theorem.<br>need urgent help

Olin [163]

Answer:

y = 7

Step-by-step explanation:

Mathematically, according to the Pythagoras’ theorem;

The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides

The hypotenuse is the side that faces the right angle and it is represented by the square root of 85 here

Thus, we have it that;

(√85 )^2= 6^2 + y^2

85 = 36 + y^2

y^2 = 85-36

y^2 = 49

y = √49

y = 7
