Answer:

The answer is ≈ 6214.78

(could put the sign because it wouldnt let me)

Step-by-step explanation:

Formulas:

A= {2} \pi r h + 2\pi r^{2}

V=\pi r^{2}h

V= A \frac{r}{2} -\pi r^{2} =1890 *\frac{9}{2} -\pi *9^{3} = 6214.77896

rounded= 6214.78

Can you please help me.<br><br><br> 6 = 4x + 9y<br><br> slove for y
kow [346]

Answer:

Step-by-step explanation:

↔Start of with your 'solution section' to make sure you have the right things↔

↔Solution 1 ➡ 4(x) + 9(y) = 16  

↔Solution 2 ➡ 6(x) - 9(y) = 8

-----------------------------------------------------------------

▪Looking for the value of the 'x'-intercept ⬇▪

◾4 (3) (y) / 2 + 4/ 3 + 9(y) = 16  

◾15(y) = 32 / 3  

◾ 45(y) = 32

▪x-intercept: 32

-----------------------------------------------------------------

◾Looking for value of the 'y'-intercept ◾

◾45(y) = 32   

◾y-intercept : 45

 ◾x = 3(y)/2+4/3 which is translated to this, am i correct? ➡ (y) = 32/45

-----------------------------------------------------------------

↪ Now, we have finally found both of their intercept ⬇

↪x-intercept: 12

↪y-intercept: 5

↪Or you can even say the intercepts in other words. Here's what I am talking about if in case you don't know what I am saying

↪x-intercept: 32✅

↪y-intercept✅

Do both of them for 50 points

Answer:

1) 5.44, 2) 3.9

Step-by-step explanation:

1) a/b + 2b - a^2 when a = 1.4 and b = 0.2

plug in the values:

1.4/0.2 + 2(0.2) - (1.4)^2 = 7 + 0.4 - 1.96 = 5.44

2) a[b-2c]^3 - d/e when a = 2, b = -0.75, c = -1, d = 0, e = -12 5/7 (rewritten to -89/7 = 12.71)

again, plug in the values:

2[-0.75-2(-1)]^3 - 0/12.71 = 2[1.25]^3 - 0 = 2[1.95] = 3.9

The admissions officer at a small college compares the scores on the Scholastic Aptitude Test (SAT) for the school's in-state an
fredd [130]

Answer:

37

Step-by-step explanation:

Here, we have two different samples, hence, to obtain the confidence interval, we use the relation for the confidence interval for two sample means ;

(x1 - x2) ± Margin of error

Where, (x1 - x2) = point estimate of the sample mean, this is the difference in mean of the two samples.

From the question ;

x1 = 1150 ; x2 = 1113

Hence, the point estimate is : (1150 - 1113) = 37
