The number of watermelon seeds in the original watermelon is 500. The second watermelon has 5% more. How many seeds are in the second watermelon?

Answer:

The commission rate is of 12%.

Step-by-step explanation:

Commission rate:

The commission rate is given by the commission value multiplied by 100% and divided by the value of merchandise sold.

In this question:

$252 in commission for selling $2100 in merchandise. So

252*100%/2100 = 12%

The commission rate is of 12%.

Answer:

Jennifer would complete the job on her own in 5 hours.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]

[tex]\Delta = b^{2} - 4ac[/tex]

Rates

The together rate is the sum of their separates rate.

We have that:

Jennifer takes x hours to complete the job on her own, so her rate is 1/x.

Carl needs 15 hours longer than Jennifer, that is, 15 + x hours, so his rate is 1/(15+x).

The together rate is 1/4. So

[tex]\frac{1}{4} = \frac{1}{x} + \frac{1}{15+x}[/tex]

[tex]\frac{1}{4} = \frac{15 + x + x}{x(15+x)}[/tex]

[tex]\frac{1}{4} = \frac{15 + 2x}{x(15+x)}[/tex]

Applying cross multiplication.

[tex]x^2 + 15x = 4(15 + 2x)[/tex]

[tex]x^2 + 15x = 60 + 8x[/tex]

[tex]x^2 + 7x - 60 = 0[/tex]

Quadratic equation with [tex]a = 1, b = 7, c = -60[/tex]. So

[tex]\Delta = 7^{2} - 4*1*60 = 289[/tex]

[tex]x_{1} = \frac{-7 + \sqrt{289}}{2} = 5[/tex]

[tex]x_{2} = \frac{-7 - \sqrt{289}}{2} = -12[/tex]

Since the time to complete the job has to be a positive value.

Jennifer would complete the job on her own in 5 hours.

Answer:

[tex] \frac{a + cd}{a} [/tex]

Step-by-step explanation:

ax - cd = a

=> ax = a + cd

[tex] = > x = \frac{a + cd}{a} [/tex]

Hence,

Option A is the answer.

Answer:

A. [tex]\frac{a+cd}{a}[/tex]

Step-by-step explanation:

ax-cd=a

Add cd to both sides:

ax=a+cd

Divide both sides by a:

x=[tex]\frac{a+cd}{a}[/tex]

If im not wrong, if every question is 2 points of 100 points in total means that are 50 questions, so if he gets 10 wrong then he would be losing 20 points which his final grade would be 80!

Answer:

Score with 10 questions wrong: 80

Score with x questions wrong: 100−2x

Step-by-step explanation:

each point is deducted by 2 pts and so, with 10 question, he got an 80.

100 is the availability of the points and 2x means which the points were lost

Answer:

We accept H₀, we don´t have enough evidence to claim that the procedure improves the tensile strength above the peviuos average

Step-by-step explanation:

Information:

μ  = 2150

Sample size    n  = 16

Sample mean   x  =  2160

Sample standard deviation    s = 30

a) Test Hypothesis

Null Hypothesis                                    H₀         x = μ

Alternative Hypothesis                         Hₐ         x > μ

b) If Tensile strength is  approximately normal distribution we should use t-student statistic for testing the above hypothesis.

t(s) = ??    with  df = n - 1      df  =  15

c)  t(s)  =  ( x - μ ) / s/√n

t(s)  = ( 2160  -  2150 ) / 30/√16

t(s)  = 10*4 / 30

t(s) = 1,33

d) In t-student we look for p-vale for 1,33 and  df = 15

p-value = 0,1

e) If the level of significance is 0,05, then    α/2 = 0,025

we compare p-value and level of significance

p-value     0,1 > 0,025

Then p-value is bigger than the significance level, we should accept H₀

Step-by-step explanation:

The equation that shows the relationship between r and w is r = w + 12 and 12 + w = r

An equation is an expression that shows the relationship between two or more numbers and variables.

Let r represent the number of minutes Diana runs and w represent the number of minutes she lifts weight.

Since Diana always spends more minutes running than lifting weights. Hence:

r = w + 12

The equation that shows the relationship between r and w is r = w + 12 and 12 + w = r

Answer:

C.

Step-by-step explanation:

The response variable can be defined as those variables that are considered to be the focus of a question in research or experiment. It is also known as a dependent variable and is marked on the y-axis. The response variable is explained with the help of an explanatory variable, marked on the x-axis. The other names for response variables are y-variables or outcome variables.

In the given case, the response variable is the grade received on each assignment. The grades received by students on each assignment are the main focus of this research.

Therefore, option C is correct.

Answer(In bold)/Step-by-step explanation:

Compute the probability that a randomly selected peanut M&M is not blue

P (blue) = 23%

P (blue)C = 1 - P(blue) = 100% - 23% = 77%

Compute the probability that a randomly selected peanut M&M is green or red.

P (green) = 15%

P (red) = 12%

P (green or red) = P(green) + P(red) = 27%

Compute the probability that three randomly selected peanut M&M’s are all yellow.

P (yellow) = 15%

(P(yellow))3 = 0.338%

There was replacement in the selection process.  

If you randomly select six peanut M&M’s, compute that probability that none of them are brown.

P(brown) = 12%

P(brown)C = 1 - P(brown) = 100% - 12% = 88%

(P(brown)C)6 = 46.440%
