The right answer for the question that is being asked and shown above is that: "D.(x – 15)2 + 94." The function f(x) = x2 + 22x + 58 is translated 4 units to the right and 16 units up. the vertex form of the new function is that D.(x – 15)2 + 94<span>
</span>
3(2 + x)
3(2) + 3(x)
<span>With the distributive property, you can multiply numbers inside parenthesis by numbers outside a parenthesis.
</span>
x(a + 1 + 4)
x(a) + x(1) + x(4)
ax + x + 4x
The number must be distributed across every term.
False because it doesn’t meet any triangle congruence theoreme
Answer: true
Step-by-step explanation:
Answer:
The 99% confidence interval for the mean number of toys purchased each year is between 7.6 toys and 7.8 toys.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 7.7 - 0.1 = 7.6 toys
The upper end of the interval is the sample mean added to M. So it is 7.7 + 0.1 = 7.8 toys
The 99% confidence interval for the mean number of toys purchased each year is between 7.6 toys and 7.8 toys.
