Answer:

112.34

Step-by-step explanation:

The 2nd digit after the decimal point is in the hundredths position.

• If the digit following is ≥ 5 then round up

• If the digit following is < 5 then leave digit as it is

here the digit following the 3 in the hundredths position is 9 so round up

112.3398 ≈ 112.34 ( to the nearest hundredth )

Answer:

10 ft²

Step-by-step explanation:

Recall that the volume of a uniform cylinder may be defined by the formula:

Volume = Base Area x Height

In our case we are given

Volume = 15 ft³ and Base Area = 1.5 ft

Substituting these known values into the formula gives:

Volume = Base Area x Height

15 = Base Area x 1.5

Base Area = 15 / 1.5

Base Area = 10 ft²

Answer:

There is no equal sign.

15         -3

-12        15

Step-by-step explanation:

The only things you can plug in are the domain {-12, -6, 3, 15}

Plug in the domain into equation to find y.

-6 :

y = -2/3 (-6) +7

y = +47

y=11

(-6,11)

3:

y = -2/3 (3) +7

y = -2 +7

y = 5

(3, 5)

15:

y = -2/3 (15) +7

y =  -10 +7

y = -3

(15 , -3)

-12:

y = -2/3 (-12) +7

y = 8 + 7

y= 15

(-12,15)

Answer:

1) 11

2) 3

3) -3

4) -12

Step-by-step explanation:

eq(1):

\(y = \frac{-2}{3} x + 7\\\\y - 7 = \frac{-2}{3} x\\\\x = (y - 7)\frac{-3}{2} \\\\x = (7-y)\frac{3}{2} ---eq(2)\)

1) x = -6

sub in eq(1)

\(y = \frac{-2}{3} (-6) + 7\\\\y = \frac{12}{3} + 7\\\\y = 4+7\\\\y = 11\)

2) y = 5

sub in eq(2)

\(x = (7-5)\frac{3}{2} \\\\x = 3\)

3) x = 15

sub in eq(1)

\(y = \frac{-2}{3} 15 + 7\\\\y = \frac{-30}{3} +7\\\\y = -10 + 7\\\\y = -3\)

4)

sub in eq(2)

\(x = (7-15)\frac{3}{2} \\\\x = -8\frac{3}{2}\\ \\x = -12\)

Answer:

c. 70

Step-by-step explanation:

Laura’s steps are 70cm, and she takes 80 steps, which would give her a total length of 5600cm. Kara’s steps are 80cm, so we have to divide 5600cm by 80cm. This means Kara takes 70 steps to walk across the park.

Answer:

\(b=\sqrt[3]{16}\)

Step-by-step explanation:

Determine interception point of curves

\(36x^2=4\)

\(x^2=\frac{4}{36}\)

\(x^2=\frac{1}{9}\)

\(x=\pm\frac{1}{3}\)

Find the area of the bounded region

\(\int\limits^\frac{1}{3} _{-\frac{1}{3}} {4-36x^2} \, dx\\ \\=4x-12x^3\Bigr|_{-\frac{1}{3} }^{\frac{1}{3} }\\\\=[4(\frac{1}{3})-12(\frac{1}{3})^3]-[4(-\frac{1}{3})-12(-\frac{1}{3})^3]\\\\=\frac{8}{9}-(-\frac{8}{9})\\\\= \frac{8}{9}+\frac{8}{9} \\\\=\frac{16}{9}\)

Therefore, since half of the area is \(\frac{8}{9}\), we can set one-half of the region between 0 and x where \(x=\frac{\sqrt{b}}{6}\) and determine b:

\(\frac{8}{9}=\int\limits^\frac{\sqrt{b}}{6} _0 {b-36x^2} \, dx\\\\\frac{8}{9} =bx-12x^3\Bigr|_{0}^{\frac{\sqrt{b}}{6} }\\\\\frac{8}{9}=b(\frac{\sqrt{b}}{6})-12(\frac{\sqrt{b}}{6})^3\\\\\frac{8}{9}=\frac{b\sqrt{b}}{6}-12(\frac{b^{\frac{3}{2}}}{216})\\\\\frac{8}{9}=\frac{b\sqrt{b}}{6}-(\frac{b^{\frac{3}{2}}}{18})\\\\\frac{16}{18}=\frac{3b\sqrt{b}}{18}-\frac{b^{\frac{3}{2}}}{18}\\\\16=3b\sqrt{b}-b^{\frac{3}{2}}\\\\16=3b^{\frac{3}{2}}-b^{\frac{3}{2}}\\\\16=2b^{\frac{3}{2}}\)

To account for both halves of the region:

\(16=2(2b^{\frac{3}{2}})\\16=4b^{\frac{3}{2}}\\4=b^{\frac{3}{2}}\\b=\sqrt[3]{16}\)

Therefore, the line \(b=\sqrt[3]{16}\) will divide the area between the curves into two regions with equal area

We will have the following:

From the polynomial we will have that:

*It falls to the left and rises to the right.

This can be seeing as follows:

The test statistic for a sample with correlation coefficient r = 0.5 and sample size n = 30 is 3.06.

To test whether a correlation is significant, we need to calculate the test statistic using the correlation coefficient (r) and the sample size (n). The formula for the test statistic is:

t = r * sqrt(n-2) / sqrt(1-r^2)
Here, r is the correlation coefficient (0.5) and n is the sample size (30).
Plugging in the given values of r = 0.5 and n = 30, we get:

t = 0.5 * √((30 - 2) / (1 - 0.5^2))
t = 0.5 * √(28 / 0.75)
t = 0.5 * √(37.33)
t = 0.5 * 6.11
t ≈ 3.06

Thus, the test statistic for this sample is approximately 3.06. To determine whether the correlation is significant, we would need to compare this test statistic to a critical value from a t-distribution with n-2 degrees of freedom at the desired significance level.

Step-by-step explanation:

The hierarchical database model is based on a tree structure, where data is organized in a parent-child relationship. Each parent segment can have multiple child segments, but each child segment has only one parent.

In this model, data access is typically navigated from the top-level parent segment to its child segments in a hierarchical manner. The parent-child relationships provide a clear structure for organizing and representing data. However, it also means that a lack of a parent segment or a child segment is not allowed in this model.

Compared to a matrix structure, where segments can have relationships with multiple other segments, the hierarchical model is more rigid in its one-to-many relationship between parent and child segments.

However, it may pose challenges when dealing with complex or interrelated data that doesn't fit neatly into a hierarchical structure.

The third degree polynomial with zeros of −3, −2, and 1, and passes through the point (2,6) is 0.3(x + 3)(x + 2)(x - 1).

We can utilize a polynomial's factored form to create a third-degree polynomial that passes through the point (2,6) and has zeros at 3, 2, and 1. Given is the factored form:

f(x) = a(x - r1)(x - r2)(x - r3)

where r1, r2, and r3 are the zeros of the polynomial and 'a' is a constant.

In this case, the zeros are -3, -2, and 1, so we have:

f(x) = a(x - (-3))(x - (-2))(x - 1)

f(x) = a(x + 3)(x + 2)(x - 1)

We will use the polynomial's passage through the point (2, 6) to determine the value of 'a'. With x = 2 and f(x) = 6, we get the following result:

6 = a(2 + 3)(2 + 2)(2 - 1)

6 = a(5)(4)(1)

6 = 20a

Solving for 'a', we find a = 6/20 = 0.3.

Now we can write the final form of the polynomial:

f(x) = 0.3(x + 3)(x + 2)(x - 1)

So, the third-degree polynomial with zeros at -3, -2, and 1, and passing through the point (2,6), is:

f(x) = 0.3(x + 3)(x + 2)(x - 1)

The probabilities are calculated assuming independence of each call and that the success probability remains constant throughout the calls.

a. The probability that, among five voters the student calls, exactly one supports candidate Smith can be calculated using the binomial probability formula. With a success probability of 64% (0.64) and exactly one success (k = 1) out of five trials (n = 5), the probability can be calculated as follows:

\[

P(X = 1) = \binom{5}{1} \times (0.64)^1 \times (1 - 0.64)^4

\]

The calculation results in approximately 0.369, or 36.9%.

b. The probability that, among five voters the student calls, at least one supports candidate Smith can be calculated as the complement of the probability that none of the voters support Smith. Using the binomial probability formula, with a success probability of 64% (0.64) and no success (k = 0) out of five trials (n = 5), the probability can be calculated as follows:

\[

P(X \geq 1) = 1 - P(X = 0) = 1 - \binom{5}{0} \times (0.64)^0 \times (1 - 0.64)^5

\]

The calculation results in approximately 0.997, or 99.7%.

c. The probability that the first voter supporting candidate Smith is reached on the fifth call can be calculated as the probability of not reaching a Smith supporter in the first four calls (0.36) multiplied by the probability of reaching a Smith supporter on the fifth call (0.64):

\[

P(\text{{First Smith Supporter on Fifth Call}}) = (1 - 0.64)^4 \times 0.64

\]

The calculation results in approximately 0.014, or 1.4%.

d. The probability that the third voter supporting candidate Smith is reached on the fifth call can be calculated as the probability of reaching two Smith supporters in the first four calls (0.64 for the first call, 0.36 for the second call, and 0.36 for the third call) multiplied by the probability of reaching a Smith supporter on the fifth call (0.64):

\[

P(\text{{Third Smith Supporter on Fifth Call}}) = (0.64)^2 \times (1 - 0.64) \times 0.64

Answer:

She has 45 Bottles left after drinking them

Step-by-step explanation:

This question needs some more clarification!

From what I read!

We know that Janelle has brought 4 cases of water containing 12 bottles in 1 case.

If she were to drink 3 bottles of water how much bottles will she have left?

First, we would have to do a multiplication problem involving the cases of water and how much bottles in one case.

Equation: 4 Cases x 12 Bottles in Each Case=48 Bottles in Total

Then, Janelle has drunk 3 bottles of water already, so we would need to subtract.

Equation 48 Bottles in Total - 3 Bottles Drunk = 45 Bottles in Total

Therefore, Janelle has 45 Bottles left in her inventory.
