Erins water bottle holds 665 milliliters. Dylan is carrying two water bottles. Each one holds 0.35 liters. Who is carrying more water?

By calculating the probability of choosing a counter at random, we find that we are least likely to choose a white counter as it has the least probability.

Probability is simply how likely something is to happen.

Probability of choosing a red counter  = 6/25 = 0.24

Probability of choosing a white counter  = 4/25 = 0.16

Probability of choosing a blue counter  = 7/25 = 0.28

Probability of choosing a yellow counter  = 8/25 = 0.32

Answer with explanation:

We know that a polynomial is classified based on the degree as follows:

Constant-

If it has a degree zero.

and the equation of such a polynomial is:

   p(x)=a

Linear--

It has degree 1.

and the equation of such a polynomial is:   p(x)=ax+b

Quadratic--

If it has degree two and the equation of the polynomial is given by:

     [tex]p(x)=ax^2+bx+c[/tex]

Based on number of Terms--

Monomial--

If it has just one term.

Binomial--

If it has two terms.

Trinomial--

If it has three terms.

We have been given a system of nonlinear equations.

[tex]\\y=40x^{2},y=19x+3[/tex]

In order to solve this system we can first equate the two equations in order to get a quadratic in x.

[tex]\\40x^{2}=19x+3[/tex]

Our next step is to bring all the terms on one side.

[tex]\\40x^{2}-19x-3=0[/tex]

Now we have to solve this equation. We can solve it by factoring using the splitting middle term method.

[tex]\\40x^{2}-24x+5x-3=0[/tex]

[tex]\\8x(5x-3)+(5x-3)=0[/tex]

[tex]\\(8x+1)(5x-3)=0[/tex]

Upon setting each of these factors equal to zero using zero product property we get

[tex]\\8x+1=0 \text{ or } 5x-3 = 0[/tex]

Upon solving both these equations we get

[tex]\\x=-\frac{1}{8} \text{ or } x=\frac{3}{5}[/tex]

Now we can substitute these values of x in the equation

[tex]y=19x+3[/tex]

We get

[tex]\text{For }x=- \frac{1}{8} \Rightarrow y=19(- \frac{1}{8})+3= \frac{5}{8}\\[/tex]

[tex]\text{For }x= \frac{3}{5}\Rightarrow y=19( \frac{3}{5})+3= \frac{72}{5}\\[/tex]

Therefore, our final set of solutions are

[tex](x,y)=(- \frac{1}{8},\frac{5}{8}) \text{ and } ( \frac{3}{5}, \frac{72}{5})[/tex]

Answer:

Option C. 140

Step-by-step explanation:

Base of a pyramid which has four triangular sides is four sided.

If pyramid contains seven layers of oranges then the layer at the bottom will have 7 oranges.

Since base is a square then other side of the square base will have the same number of oranges = 7.

Therefore number of oranges at the first layer will be = 7×7

Similarly other layers above this layer will have the same sequence

6×6, 5×5, 4×4, 3×3, 2×2, 1×1

Therefore total number of oranges = 7×7 + 6×6 + 5×5 + 4×4 + 3×3 + 2×2 + 1×1 = 49 + 36 + 25 + 16 + 9 + 4 + 1 = 140

Option C. 140 is the answer.

A grocer stacks oranges in a four-sided pyramid that is 7 layers high. Many oranges are in the pile are C.140

The orange is the fruit of the citrus species Citrus and sinensis in the family Rutaceae, native to China. Orange is also called sweet orange, to distinguish it from the related Citrus and aurantium, referred to as bitter orange.

The proper name of four-sided pyramid is a "tetrahedron". The tetrahedron has the extra interesting property of having all four triangular sides congruent

1st Layer: The 1st layer contains only 1 orange so it has only 1 orange

2nd layer: The 2nd layer has total 4 oranges. Calculation:   [tex]2*2=4[/tex]

3rd layer: The 3rd layer has total 9 oranges. Calculation: [tex]3 * 3 = 9[/tex]

4th Layer: The 4th layer has total 16 oranges. Calculation: [tex]4 * 4 = 16[/tex].

5th layer: The 5th layer has total 25 oranges. Calculation:  [tex]5 * 5 = 25[/tex]

6th layer: The 6th layer has total 36 oranges. Calculation: [tex]6 * 6 = 36[/tex]

7th layer: The 7th layer has total 49 oranges. Calculation: [tex]7 * 7 = 49[/tex].

Sum of all layers:

[tex]1+4+9+16+25+36+49 = 140[/tex]

Step-by-step explanation:

How do do a 3/4 as a fraction, decimal, and percent?

1) 3/4 is just a fraction

2) 3:4 = 0.75 (0.75 = 75%)

3) 75%

Solution: The test statistic under the null hypothesis is:

[tex]t=\frac{\bar{x_{1}}-\bar{x_{2}}}{s_{p}\sqrt{(\frac{1}{n_{1}})+(\frac{1}{n_{2}})}}[/tex]

Where:

[tex]s_{p} = \sqrt{\frac{(n_{1}-1)s^{2}_{1}+(n_{2}-1)s^{2}_{2}}{n_{1}+n_{2}-2} }[/tex]

[tex]s_{p} = \sqrt{\frac{(16-1)14.8^{2}+(18-1)16^{2}}{16+18-2} }[/tex]

               [tex]=15.45[/tex]

[tex]\therefore t=\frac{85.4-74.9}{15.45\sqrt{(\frac{1}{16})+(\frac{1}{18})}}[/tex]

                   [tex]=\frac{10.5}{5.31}[/tex]

                   [tex]=1.98[/tex]

Now, to find the critical values, we need to use the t distribution table at 0.01 significance level for [tex]df=n_{1} + n_{2} -2 = 16+18-2=32[/tex] and is given below:

[tex]t_{critical}=-2.738,2.738[/tex]

Since the t statistic is less than the  t critical value, we therefore fail to reject the null hypothesis and conclude that the two population means are equal.

a) What proportions of passes were completed?

b) How does this compare with what “should have happened” theoretically?"

First, take 100 numbers, i.e. from 00 to 99, and set that the first 54% are completed passes, therefore from 00 to 53, and the remaining 46% are not completed passes, therefore from 54 to 99.

Now, divide the random digits until you compose 20 numbers: 98, 72, 61, 09, 83, 56, 23, 94, 20, 42, 76, 52, 06, 82, 76, 58, 23, 94, 87, 29.  

Then, divide the numbers into the two set categories: 

completed: 09, 23, 20, 42, 52, 06, 23, 94, 87 = 9 outcomes
not completed: 98, 72, 61, 83, 56, 94, 76, 82, 76, 58, 29 = 11 outcomes

A) Therefore, from the random digits you get 9/20 = 45% of completed passes and 11/20 = 55% of not completed passes.

B) Using the random digits, the simulation gave an outcome exactly opposite to what we expected.

Answer:

the answer is 675

Step-by-step explanation:

1. there is a tank with 1000 gallons, and we have 65 cans with a capacity of 5 gallons, so if we multiply the 65 cans with the capacity we would have as result

  65 x 5 = 325

2-  already having the value of gallons used (325) we can subtract this difference to the 1000 gallons that were in the tank at first.

 1000 - 325 = 675
