Answer:

.375 which is 3/8

Step-by-step explanation: If you meant the mixed fraction 2 1/4 divided by 6 then that is the answer! 2 1/4 =2.25 and divide it by 6 and you get 0.375

Answer:

3/8

Step-by-step explanation:

convert mixed numbers to improper fractions

21/4 = 9/4

convert element to fraction

6=6/1

9/4 divided by 6/1

apply the fraction rule (hope you're familiar)

9/4 * 1/6

cross- cancel common factor 3

3*1 = 3

4*2 = 8

multiply the numbers

3/ 4*2

3/8

Answer:

equation: 3x - 20 = 0

Step-by-step explanation:

3x = 20

add its opposite to both sides.

3x - 20 = 20 - 20

= 3x - 20 = 0

Answer:

h = 79 m

Step-by-step explanation:

The length of the string, H = 125 m

The kite forms 39° angle.

We need to find the height of the kite. Let it is h. We can find it using trigonometry i.e.

[tex]\sin\theta=\dfrac{P}{H}[/tex]

Where

P is perpendicular and H is Hypotenuse

So,

[tex]\sin\theta=\dfrac{h}{H}\\\\h=H\times \sin\theta\\\\h=125\times \sin(39)\\\\h=78.66\ m[/tex]

or

h = 79 m

So, the kite is flying at a height of 79 m.

Answer:

The sample mean is of 1925 calories.

The margin of error is of 75 calories.

The sample standard deviation is of 109.7992 calories.

Step-by-step explanation:

Sample mean:

The sample mean is the mean value of the two bounds of the confidence interval. So

[tex]M = \frac{1850 + 2000}{2} = 1925[/tex]

The sample mean is of 1925 calories.

The margin of error

Difference between the bounds and the sample mean. So

2000 - 1925 = 1925 - 1850 = 75 calories.

The margin of error is of 75 calories.

Sample standard deviation:

Here, I am going to expand on the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 18 - 1 = 17

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.898

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

Since [tex]M = 75, T = 2.898, n = 18[/tex]

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

[tex]75 = 2.898\frac{s}{\sqrt{18}}[/tex]

[tex]s = \frac{75\sqrt{18}}{2.898}[/tex]

[tex]s = 109.7992[/tex]

The sample standard deviation is of 109.7992 calories.

Answer:

its 25 percent

Step-by-step explanation:

want an explanation cuz im happy to give you 1

Given :

Number of methods, k = 3

Number of the observations, n = 30

Degrees of freedom Treatment = k - 1

                                                     = 3 - 1 = 2

Degrees of freedom for error = n - k

                                                 = 30 - 3 = 27

[tex]$SSTR = 4560, \ SST = 10800$[/tex]

[tex]$SSE = SST - SSTR$[/tex]

       = 10800 - 4560

       = 6240

[tex]$SSE_{treatment} = MS_{treatment } \times DF_{treatment}$[/tex]

[tex]$MS_{treatment} = \frac{4560}{2}=2280$[/tex]

[tex]$MS_{error}=\frac{SSE_{error}}{DF_{error}}$[/tex]

             [tex]$=\frac{6240}{27}=231.1$[/tex]

[tex]$F=\frac{MS_{treatment}}{MS_{error}}$[/tex]

  [tex]$=\frac{2280}{231.1}=9.865$[/tex]

Source variation   Sum of square  Degrees of freedom  Mean square     F

Treatment                   4560                          2                         2280       9.8653

Error                            6240                         27                   231.11111111

Total                            10800

The critical value of F for the 0.05 sig level and df (227) is 3.354

Since the test stat > critical value of F, so we reject null hypothesis and state that there is a significant difference in the means of the three assembly methods.

Answer:

[tex]\$1320[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be the number of units of A

[tex]y[/tex] be the number of units of B

For assembling we have

[tex]20x+25y\leq 3000[/tex]

For packaging we have

[tex]10x+5y\leq 1200[/tex]

Let profits earned be [tex]Z[/tex] so

[tex]Z=10x+8y[/tex]

We have the maximize the function.

Plotting the equations we can see that the intersection points are [tex](0,120),(100,40),(120,0)[/tex]

In the question it is mentioned we have to sell both the products so [tex]x[/tex] or [tex]y[/tex] cannot be [tex]0[/tex].

So, the point of maximiztion for the function would be [tex](100,40)[/tex]

The maximum profit would be

[tex]Z=10\times 100+8\times 40\\\Rightarrow Z=1320[/tex]

Answer:

15x + 7

Step-by-step explanation:

i set this up

8x + 16 + 7x -9

the next step is to combine like terms

8x + 7x = 15x

16 - 9 = 7

15x = 7

15x + 7

Step-by-step explanation:

I took the test

Answer:

x = 136°

y = 44°

Step-by-step explanation:

x + 44° = 180° (Adjacent angles of a parallelogram)

x = 180° - 44°

x = 136°

y = 44° (Opposite angles of a parallelogram)

Ok. So if 42 % is apple, then 63 = 42%.

You can divide it by 42 to get 1%

63 / 42 = 1.5

Than times by 100 to get 100%

100% = 150.

Answer:3255.20

Step-by-step explanation:

First, calculate the interest using the APR in decimal form (divided by 12) and the average daily balance.

Interest =0.27612×$2,400=$55.20

Then add the interest to the unpaid balance.

Total Balance =$3,200+$55.20=$3,255.20
