Answer:

V ≈ 50.27 cubic feet

Step-by-step explanation:

V = π * r^2 * h/3

V = π * 16 * 3/3

V = 16π

V ≈ 50.27 cubic feet

When solving these proportions we just remember when moving a number from one side to the other if it started in the numerator it ends up in the denominator and vice versa.

I'll do it in two steps here for teaching purposes; it's not too hard to go directly to the answer.

$\dfrac{13}{7} = \dfrac{10}{v}$

$13 v = 7(10)$

$v= \dfrac{7 \cdot 10 }{13} = \dfrac{70}{13} \approx 5.4$

Here is the histogram of a data distribution. All class widths are 1.

stich3 [128]

The median of the data is 5 if the all class widths are 1, option (C) is correct.

<h3>What is the median?</h3>

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

In the histogram, 15 data values are given:

1, 2, 2, 3, 3, 3, 4, 5, 6, 6, 7, 7, 7, 8, 9

The mid-value is 5 which is on the 8th place

Thus, the median of the data is 5 if the all class widths are 1, option (C) is correct.

What values for theta (0 less than or equal to theta less than equal to 2pi) satisfy the equation?

Novosadov [1.4K]

Solve this as you would an equation that does not involve trig. Don't let the trig scare you. If you had to solve 2x+8=0, the first thing you would do is factor out the common 2. In our equation, we have a common cos theta. I'm going to use beta as my angle. When we factor out beta, here's what we have. $cos \beta (2sin \beta +1)=0$ . The Zero Product Property tells us that at least one of those factors has to equal zero. So we set them both equal to zero and solve. Let's get the equations first, then we will need our unit circle. First equation set to equal zero is $cos \beta =0$ . On our unit circle, cos is the value inside the parenthesis that is in the x position within our coordinate. Look at all those coordinates as you go around the unit circle once (once around is equivalent to 2pi). You will find that the the cos is 0 at $\frac{ \pi }{2}, \frac{3 \pi }{2}$ . The next equation is $2sin\beta +1=0$ . Move the 1 over by subtraction and divide by 2 to get $sin \beta =- \frac{1}{2}$ . Same as before, go around the unit circle one time and look to see where the coordinate in the y place is -1/2. Sin corresponds to the y coordinate. You will find that sin is -1/2 at $\frac{7 \pi }{6}, \frac{11 \pi }{6}$ . And there you go! Trig is so much fun!!!

Please help for Q4 I’m super lost. Write an expression for the sum of four consecutive odd numbers where 2n+1 is the smallest od

sveta [45]

Answer:

n+2

Step-by-step explanation:

This is a Typical Question on Arithmetic Progression with initial term as 2n+1

The next number in this particular series will be 2n+1+2 which is 2n+3 and so on. Thus a common difference of 2 exists.

The nth term of an Arithmetic Progression AP, bn is represented below where b1 is the first term

bn=b1 +(n-1)d where d is the common difference

For this particular series, the 4th term b4 is

b4= 2n+1+(4-1)2 0r b4 =2n+1+6=2n+7

sum of series is represented by equation: n(b1 +b4)/2 where b1 and b4 are 1st and 4th term respectively

Thus Sum required =4(2n+1+2n+7)/2=4(4n+8)/2=8n+16 0r n+2
