Answer:
1:yes 2:no 3:no 4:yes
Step-by-step explanation:
3*2=6 for the numerators
4*5=20 for the denominators
you can simplify this to make it 3/10 ✔️
2*5-10 for the numerators
6*5=30 for the denominators
you can simplify this to make it 1/3 ❌
1*1=1 for the numerators
10*5 for the denominators
you can turn this into 1/50 ❌
1*3=3 for the numerators
2*5=10 for the denominators
you can turn this into 3/10 ✔️
hope this helps! have a nice day! :)

Answer:
Option C
Step-by-step explanation:
Given that for a random sample of 20 houses selected from a city showed that the mean size of these houses is 1880 square feet with a standard deviation of 320 square feet.
X, the sizes of houses is Normal
Hence sample mean will be normal with
Mean = 1880
and std dev = 
For 90% confidence interval critical value for t with degree of freedom 19 is
1.328
Confidence interval upper bound
= mean + margin of error
= 
Option C is right
So, to factor out the equation x²+12x+35, first multiply the first and last numbers.
1×35=35
So, you need to find the multiples of 35 that add up to 12.
So, you find 7 and 5. These two numbers are the magic numbers that will be used as the correct factored form of x²+12x+35, because:
>7×5=35
>7+5=12
So, using these two numbers, you get your factored form as:
(x+5)(x+7)
