Sydney says that altogether they have placed 2/3 of the eggs into Tanks A and B. Is Sydney correct?

-1/6 of the eggs into Tank A

-4/9 of the eggs into Tank B

Answer:

Amount of shampoo in a bottle = 30 \frac{1}{2} 30

ounces

Amount of shampoo Nico uses in one bathe for his dog = 1 \frac{1}{4} 1

Since 3 ounces of shampoo is spilled out, the amount of shampoo left in the bottle will be = 27 \frac{1}{2} 27

If Nico can Bathe his dog x times using this bottle, the value of x can be written as:

x= \frac{27 \frac{1}{2} }{ 1\frac{1}{4} } x=

4

1

27

1

Using this equation we can find the number of times Nico can use the shampoo to Bathe . The value of x comes out to be 22.

Thus, Nico can Bathe his dog 22 times using the bottle

Nico dropped the brand new bottle of dog shampoo and 3 ounces spilled out. He measures 1 1/4 ounces each time he shampoos his dog and the bottle of shampoo originally contained 30 1/2 ounces. Which is the correct equation and value of x, the number of times Nico can bathe his dog using this one bottle?

Answer:

b.

Step-by-step explanation:

From the given information:

Null and alternative hypothesis is:

[tex]H_o : \mu _{france} = \mu_{switzerland} \\ \\ H_a : \mu _{france}\neq \mu_{switzerland}[/tex]

Given:

Number of babies   France    Switzerland

Sample size (n)         100                100

Mean                         1.85               1.65

SD                              1.3                 1.2

The test statistics can be computed as:

[tex]Z = \dfrac{\bar x_{france} - \bar x_{switzerland}}{\sqrt{\dfrac{s_1^2}{n_1}+\dfrac{s_2^2}{n_2}}}[/tex]

[tex]Z = \dfrac{1.85- 1.65}{\sqrt{\dfrac{1.3^2}{100}+\dfrac{1.2^2}{100}}}[/tex]

[tex]Z = \dfrac{0.2}{\sqrt{0.0313}}[/tex]

[tex]Z = 1.130[/tex]

degree of freedom = [tex]n_1 + n_2 -2[/tex]

= 100 + 100 -2

= 200 -2

=198

At 0.05, using the [tex]t_{dist}[/tex] table;

P-value = [tex]t_{dist} (1.130,198,2)[/tex]

P-value = 0.258

Since P-value is greater than ∝ = 0.05, We fail to reject [tex]H_o[/tex]

We conclude that there is No statistical difference at the 0.05 level. Hence [tex]\mu_{france} \neq \mu_{switzerland}[/tex]

The significance level shows that there is no sufficient evidence to conclude that there is a difference in the average number of babies as B. Test statistics z= 1.13 and p-value is 0.258

It should be noted that a significance level simply means the probability that an event could have taken place by chance.

In this case, the test statistic will be:

= (1.85 - 1.65)/(✓1.3²/100 + 1.2²/100)

= 1.13

This is a two tailed test. Therefore, the p value will be:

= 2(1 - 0.87076)

= 0.258

Therefore, the p value is more than 0.05 and there's no sufficient evidence to reject the null hypothesis.

A. For every 1 inch of mercury the pressure increases, the boiling point is expected to increase by 1.9°F

Step-by-step explanation:

A regression model is in the form :

y = mx + c

With m being the slope = rate of change

In regression, the value of the slope gives the rate of change in y value per unit increase in the value of x

The slope in the question above is 1.9, this means for every unit increase in mercury pressure, then boiling point, y increases by 1.9°F

The possible values of X are 0,1 or 2.

Step-by-step explanation:

In this question:

Two number cubes are going to be rolled.

X is the number of odd numbers that show up on the two cubes.

For each cube, there is one number, which can be even, or odd.

Thus, there can be no odd numbers, one odd number or two odd numbers, and the possible values of X are 0,1 or 2.

Answer:

40 yards

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

Using this, let's set the length as x.

42² + x² = 58²

Simplify.

1764 + x² = 3364

Subtract 1764 from both sides.

x² = 1600

Take the square root.

x = 40

The elevation of the city with an elevation opposite Seeley's is -45 feet. The correct option is A.

Trigonometry is a branch of mathematics that deals with the study of the relationships between the sides and angles of triangles, and the calculations based on these relationships. It specifically focuses on the ratios between the sides of a right-angled triangle.

The elevation of a city with an elevation opposite of Seeley's can be found by taking the opposite of Seeley's elevation, which is 45 feet, to get the answer.

Therefore, the elevation of the city with an elevation opposite of Seeley's is:

Median value = 73

Midrange = (Maximum + minimum) / 2

Midrange = (85 + 41) / 2 = 126 / 2 = 63

Geometric mean : √(x1*x2*.. xn)^1/n

Geometric Mean:

Answer:

x = -3, y = -3

Step-by-step explanation:

Solve the following system:

{-y + 2 x = -3 | (equation 1)

3 y + 4 x = -21 | (equation 2)

Swap equation 1 with equation 2:

{4 x + 3 y = -21 | (equation 1)

2 x - y = -3 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{4 x + 3 y = -21 | (equation 1)

0 x - (5 y)/2 = 15/2 | (equation 2)

Multiply equation 2 by 2/5:

{4 x + 3 y = -21 | (equation 1)

0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:

{4 x + 3 y = -21 | (equation 1)

0 x+y = -3 | (equation 2)

Subtract 3 × (equation 2) from equation 1:

{4 x+0 y = -12 | (equation 1)

0 x+y = -3 | (equation 2)

Divide equation 1 by 4:

{x+0 y = -3 | (equation 1)

0 x+y = -3 | (equation 2)

Collect results:

Break even unit = 800

Break even point = $320,000

Step-by-step explanation:

Given:

Amount invested (Fixed cost) = $200,000

Each software cost (variable cost) = $150

Selling price = $400

Find:

Break even unit

Computation:

Assume;

Break even unit = a

Total Cost = Amount invested (Fixed cost) + [Each software cost][Break even unit]

Total cost = 200,000 + 150a

Total revenue = Selling price[Break even unit]

Total revenue = 400a

So,

400a = 200,000 + 150a

250a = 200,000

Break even unit = 800

Break even point = 400a

Break even point = 400(800)

Break even point = $320,000
