Answer:

12.3 = y

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj/ hyp

cos 35 = y/15

15 cos 35 = y

12.28728066 = y

To the nearest tenth

12.3 = y

Answer:

Neither, they increase by the exact same amount.

Step-by-step explanation:

With the first data set you have a mean of 50 and a median value of 50 as well because to find a median of an even set of numbers you take the two middle values and average them together, in this case being 35 and 65 averaging out to 50. Adding 155 to this data set increases the mean to 65 and the median value to 65 as well, making this a trick question because the increase is the exact same.

Multiplication is the process of multiplying. The value of the expression 10 × 4,000 is 40,000.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

In the given expression 10×4000, the symbol of '×' represents that the two digits should be multiplied. Therefore, the value of the multiplication of 10 and 4,000 is,

10 × 4,000 = 40,000

Hence, the value of the expression 10 × 4,000 is 40,000.

Answer:

The P-value is 0.0234.

Step-by-step explanation:

We are given that a statistics practitioner calculated the mean and the standard deviation from a sample of 400. They are x = 98 and s = 20.

Let = population mean.

So, Null Hypothesis, : = 100 {means that the population mean is equal to 100}

Alternate Hypothesis, : > 100 {means that the population mean is more than 100}

The test statistics that will be used here is One-sample t-test statistics because we're yet to know about the population standard deviation;

T.S. = ~

where, = sample mean = 98

s = sample standard deviation = 20

n = sample size = 400

So, the test statistics = ~

= -2

The value of t-test statistics is -2.

Now, the P-value of the test statistics is given by;

P( < -2) = 0.0234 {using the t-table}

Answer:

288π cm³, 904.32 cm³, and 904.778683 cm³

Step-by-step explanation:

The volume of a sphere can be found using the following formula.

[tex]V=\frac{4}{3} \pi r^3[/tex]

We are given the diameter, so we must find the radius.

The radius is half of the diameter.

r= d/2

The diameter is 12 cm.

r= 12 cm/2

r= 6 cm

The radius is 6 centimeters. Let's return to the formula and substitute 6 cm in for r.

[tex]V=\frac{4}{3} \pi (6cm)^3[/tex]

Evaluate the exponent.

[tex](6 cm)^3= 6 cm * 6 cm * 6cm = 36 cm^2 * 6cm= 216 cm^3[/tex]

[tex]V=\frac{4}{3} \pi * 216 cm^3[/tex]

Multiply 4/3 and 216 cm^3

[tex]V= (\frac{4}{3} * 216 cm^3)\pi[/tex]

In terms of pi:

[tex]V= 288\pi cm^3[/tex]

Using 3.14 as pi:

[tex]V= 288 \pi cm^3[/tex]

[tex]V= (288 * 3.14) cm^3[/tex]

[tex]V= 904.32 cm^3[/tex]

Using 3.14159265 as pi:

[tex]V= 288 \pi cm^3[/tex]

[tex]V= (288 * 3.14159265) cm^3[/tex]

[tex]V=904.778683 cm^3[/tex]

The volume of the sphere is 288π cm³, 904.32 cm³, and 904.778683 cm³

Answer:

Volume of sphere by formula is V= 4/3πr^3

Since d= 12

Then r = d/2

Radius = diameter / 2

r = 12/2

r = 6

V = 4/3 x 22/7 x 6^3

V = 1.33 x 3.14 x 216

V = 902.1cm^3....

Step-by-step explanation:

The table and the plotted data are in the attachment.

Answer and Step-by-step explanation: A line of best fit is the best approximation of the given data. It is used to show the relation of two variables and it can be determined, more accurately, by the Least Square Method.

To use the method, follow the steps:

1) Calculate the mean of the two variables:

[tex]X = \frac{\Sigma x_{i}}{n}[/tex]

[tex]Y=\frac{\Sigma y_{i}}{n}[/tex]

2) The Slope of the line is given by:

[tex]m=\frac{\Sigma (x_{i}-X)(y_{i}-Y)}{\Sigma (x_{i}-X)^{2}}[/tex]

3) The y-intercept is found by the formula:

[tex]b=Y-mX[/tex]

For the ripening of bananas, the least square method gives the line:

y = -0.142x + 5.56

The rate of change of a line equation is its slope, so

Rate of change = -0.14

The rate of change of ripening time with respect to exposure time is -0.14, which means the more expose the fruit is, the less time it needs to ripe.

Answer:

4

Step-by-step explanation:

So we know that RT is 36.

Note that RT is the combined length of RS and ST. Therefore:

[tex]RT=RS+ST[/tex]

Substitute. RT is 36, RS is 6x+1 and ST is x+7:

[tex]36=(6x+1)+(x+7)[/tex]

Combine like terms and add:

[tex]36=7x+8[/tex]

Subtract 8 from both sides:

[tex]28=7x[/tex]

Divide by 7:

[tex]x=4[/tex]

So, our answer is 4 :)

Smaller t = 2

Larger t = 5

Step-by-step explanation:

Given:

The given function is.

Find the zeros of the function.

Solution:

Simplify the equation above equation.

Now, we first find the root of the above equation.

Use quadratic formula with .

Put a, b and c value in above equation.

For positive sign

t = 2

For negative sign

t = 5

Put t = 2 in given function.

Put t = 5 in given function.

So, the zeros of the function is t = 2 or 5

Therefore, the smaller value of t = 2 and larger value of t = 5.

Following B. O. D. M. A. S rule :

= { [ 8 / 2] ^2 - 6} * (-2)

= { 4 ^ 2 - 6} * - 2

= 10 * - 2

= - 20

Answer:

Solution : - 20

Step-by-step explanation:

We have the following expression to simplify,

[tex]\left\{\left[\frac{\left(3+5\right)}{2}\right]^2-\left(3\cdot 2\right)\right\}\cdot \left(-2\right)[/tex]

Let's start by simplifying simple expressions, such as 3 + 5 = 8 and 3 * 2 = 6. Substituting we receive,

[tex]\left\{\left[\frac{\left(8\right)}{2}\right]^2-\left(6\right)\right\}\cdot \left(-2\right)[/tex]

8 / 2 = 4, and 4² = 16 -

[tex]\left\{16-\left(6\right)\right\}\cdot \left(-2\right)[/tex]

And of course 16 - 6 = 10, simplifying the expression to " - 2 [tex]*[/tex] 10 " leaving us with a solution of - 20.

Answer:

There is sufficient evidence to conclude that the new algorithm has a lower mean completion time than the current algorithm

Step-by-step explanation:

From the question we are told that

    The  sample size for each algorithm is [tex]n_1 = n_2 = n = 61[/tex]

     The sample mean  for new algorithm is  [tex]\= x_1 = 14.06 \ hr[/tex]

     The  standard deviation for new algorithm is  [tex]\sigma _1 = 3.004 \ hr[/tex]

     The  sample  mean for  the current algorithm is  [tex]\= x_2 = 16.43 \ hr[/tex]

     The standard deviation for current algorithm is  [tex]\sigma _2 = 4.568[/tex]

     The  level of significance is [tex]\alpha = 0.05[/tex]

The  null hypothesis is  [tex]H_o : \mu_1 = \mu _2[/tex]

The  alternative  hypothesis is [tex]H_a : \mu_1 < \mu_2[/tex]

Here  [tex]\mu _1 \ and \ \mu_2[/tex] are population mean for  new and current algorithm

Generally the test statistics is mathematically represented as

       [tex]Z = \frac{ \= x _1 - \= x_2 }{ \sqrt{\frac{ \sigma_1 ^2 }{n_1} + \frac{\sigma^2_2 }{ n_2}} }[/tex]

=>    [tex]Z = \frac{ 14.06 - 16.43 }{ \sqrt{\frac{ 3.004^2 }{61} + \frac{4.568^2 }{ 61}} }[/tex]

=>    [tex]Z = -3.39[/tex]

Generally the p-value is mathematically represented as

     [tex]p-value = P(Z < -3.39 )[/tex]

From the  z-table  

             [tex]P(Z < -3.39 ) = 0.0003[/tex]

=>    [tex]p-value = P(Z < -3.39 ) = 0.0003[/tex]

From the calculated value  we see that  [tex]p-value < \alpha[/tex]  hence the null hypothesis is rejected

        Hence we can conclude that there is sufficient evidence to conclude that the new algorithm has a lower mean completion time than the current algorithm
