Step-by-step explanation:
y=(1+2z+3z^3)(5z+8z^2-Z^3)
Answer:
Step-by-step explanation:
multiplying the first bracket with the second (step by step)
= 1( 5z + 8z^2 - z^3) +2z ( 5z + 8^2 - z^3 )+3z^3 (5z + 8^2- z^3)
= 5z + 8z^2 - z^3 + 10z^2 + 16z^3 - 2z^4 + 15z^4 + 24z^5 -3z^6
=5z + 16z^2 + 15z^3 + 17z^4 + 24z^5 -3z^6

What is the z-score with a confidence level of 95% when finding the margin of error for the mean of a normally distributed population from a sample? 0.99 1.65 1.96 2.58
The value of z-score with a confidence level of 95% in finding margin of error for the mean of a normally distributed population from a sample is 1.96.
What is normally distributed data?Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data.The standard deviation of the data is the half of the difference of the highest value and mean of the data set.The confidence level is 95% when finding the margin of error for the mean of a normally distributed population from a sample.
The critical z score value for the confidence level of 95% is 1.96 and +1.96 standard deviation.
Thus, the value of z-score with a confidence level of 95% in finding margin of error for the mean of a normally distributed population from a sample is 1.96.

Jim’s mom ordered 9 pizzas for his party. If each person eats 1/3 of a pizza, how many people can eat pizza at Jim’s party?
Answer:
27 people can eat pizza at Jim's Party
Step-by-step explanation:
If you divided each pizza by 3, 3 people a pizza right, so 3 x 9 would get you the number of people that can eat pizza at the party, hope this helps! :D
In the given circle with the centre O,
angle ABC = 100° angleACD = 40° and CT is a tangent to the circle at C. Find Angle ADC and Angle DCT.
Step-by-step explanation:
As the points A, B, C and D lie on a circle, So, ABCD is a cyclic quadrilateral...
As, Sum of opp. ∠s in a cyclic quadrilateral = 180°
∴ ∠ADC + ∠ABC = 180°
=> ∠ADC + 100° = 180° => ∠ADC = 80°
Now,
Sum, of all angles in a traingle = 180°
In ΔACD, ∠CAD + ∠ADC + ∠ACD = 180°
=> ∠CAD + 80° + 40° = 180°
=> ∠CAD = 180° - 80° - 40° = 60°
As CT is tangent to the circle at the point C and CD is a chord of the circle, So
∠DCT = ∠CAD........(∠s in alternate segments are equal,,So ∠CAD = 60°)
=> ∠DCT = 60°
Hope it helps you!!Answer:
See below ~
Step-by-step explanation:
∠ADC
∠ABC + ∠ADC = 180° (Angles in a cyclic quadrilateral)∠ADC = 180° - 100° = 80°∠DCT
∠DCT = ∠CAD (ANGLES IN ALTERNATE SEGMENTS EQUAL)∠CAD = 180° - 80° - 40° = 60°∠DCT = 60°What is the area of this figure?

A parallelogram has an area of 37 square feet. If the height of the parallelogram is 4 feet, how many feet is the base?
Answer:The base of the given parallelogram is
Step-by-step explanation:Area of a parallelogram is defined as the product of its base and height respectively. Mathematically;
→ Area of parallelogram = base * height
By substituting the given values in the formula, we get the following results:
→ 37 = base * 4
→ base = 37/4
→ base = 9.25
Hence, the base of the given parallelogram is 9.25 feet.
Additional information:Let's know something more about a parallelogram.
What is a parallelogram?
A parallelogram is a special type of quadrilateral whose opposite sides are parallel and hence its opposite angles are also parallel.
What is the formula of a parallelogram?
Let ‘B’ be the base and ‘H’ be the height of a parallelogram then its area is given by,
→ Area of parallelogram = B * H
What is unit of parallelogram?

Find the sum of the first 6 terms of the following sequence. Round to the nearest
hundredth if necessary.
324,
54,
9….
Answer:
388.79 (nearest hundredth)
Step-by-step explanation:
Given sequence: 324, 54, 9, ...
Therefore:
[tex]a_1=324[/tex]
[tex]r=\textsf{common ratio}=\dfrac{54}{324}=\dfrac16[/tex]
Sum of a finite geometric series:
[tex]S_n=\dfrac{a_1-a_1r^n}{1-r}[/tex]
Sum of the first 6 terms → n= 6:
[tex]\begin{aligned}S_6 & =\dfrac{324-324(\frac16)^6}{1-\frac16}\\ & =\dfrac{324-\frac{1}{144}}{1-\frac16}\\ & =\dfrac{9331}{24}\\ & = 388.79\:\textsf{(nearest hundredth)}\end{aligned}[/tex]
So
[tex]\\ \rm\Rrightarrow S_n=\dfrac{a-ar^n}{1-r}[/tex]
[tex]\\ \rm\Rrightarrow S_6=\dfrac{324-324(1/6)^6}{1-1/6}[/tex]
[tex]\\ \rm\Rrightarrow S_6=\dfrac{324-\dfrac{1}{12^2}}{\dfrac{5}{6}}[/tex]
[tex]\\ \rm\Rrightarrow S_6=\dfrac{9331}{24}=388.79[/tex]

Which of the following is the inverse of y=3"?
Answer:
[B] [tex]y=log_3x[/tex]
Step-by-step explanation:
Given:
[tex]y=3^x[/tex]
Exchange the variables:
[tex]x=3^y[/tex]
Putting the variable y on the left side of the equation:
[tex]3^y=x[/tex]
Applying the logarithm properties:
[tex]y=log_3(x)[/tex]
Thus,
[tex]f^-^1=log_3(x)[/tex]
Hence, the answer is [B] [tex]y=log_3x[/tex]
