lina2011 [118]3 years ago
5 0

Answer:

5

Step-by-step explanation:

Given :

Observed values = 5, 10, 15

Expected freqencies = 10

χ² = Σ(observed - Expected)² / Expected

χ² = (5-10)²/10 + (10-10)²/10 + (15-10)²/10

χ² = 25/10 + 0/10 + 25/10

χ² = 2.5 + 0 + 2.5

χ² = 5

lord [1]

Answer:

f(4) = 9

Step-by-step explanation:

f left parenthesis x right parenthesis equals x squared minus 3 x plus 5

f(x) = x² - 3x + 5

f left parenthesis 4 right parenthesis equals

f(4) =

f(x) = x² - 3x + 5

When x = 4

f(4) = 4² - 3(4) + 5

= 16 - 12 + 5

= 9

f(4) = 9

Find the greatest common factor!<br> Please help with these 2 questions
Aleksandr-060686 [28]

Hello!

The greatest common factor (GCF) is self explanatory. We find the factors of each number, and find the largest ones that are in common

12: 1,12,2,6,3,4

33:1,33,3,11,

As you can see, the greatest number these two have in common is 3.

Now for the next set.

45: 1,45,3,15,5,9

70:1,70,2,35,5,14,7,10

As you can see, our GCF is 5.

Therefore, our answers are below.

9) 3

10) 5

I hope this helps!

sp2606 [1]

Answer:

Ask yourself: "Can I roll a prime number and an odd number at the same time?"

Since the answer is "yes it is possible" (eg: rolling a 3), this means the two events are not mutually exclusive. Mutually exclusive events have nothing in common.

In terms of a venn diagram, mutually exclusive events have no overlapping shared region.Step-by-step explanation:
