Unit conversion is a way of converting some common units into another without changing their real value. The lemonade left with Tony is 4500ml.

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

One litre is equal to 1000 millilitres. Tony made 14 Liter of lemonade, therefore, Tony made 14,000 millilitres of lemonade. His guest drank 9500 millilitres. Therefore, the lemonade left with Tony is,

Lemonade left = 14,000 - 9,500 = 4,500 ml

Hence, the lemonade left with Tony is 4500ml.

Answer:

system

equations

Step-by-step explanation:

Answer:

A system of two linear equations can have one solution, an infinite number of solutions, or no solution.

===================================================

Explanation:

An equation is something like [tex]\text{y} = 2\text{x}+5[/tex] and [tex]\text{y} = 3\text{x}+7[/tex]

When we combine two such equations to form a group (of sorts), we consider this to be a system of equations.

We use a single curly brace to write the system

[tex]\begin{cases}\text{y} = 2\text{x}+5\\\text{y} = 3\text{x}+7\end{cases}[/tex]

Here are the three cases mentioned when it comes to solutions.

Side note:  Any solution is of the form (x,y)

The function with the same end behavior of f(x) is the last option:

[tex]g(x) = (-\frac{1}{3} )*x[/tex]

By looking at the graph, we can see that the end behavior of f(x) is:

as x → ∞; f(x) → -∞

as x → -∞; f(x) → ∞

Then we just want a function that depends linearly with x and that has a negative coefficient.

The correct option is the last one:

[tex]g(x) = (-\frac{1}{3} )*x[/tex]

Where clearly, when x tends to infinity the function tends to negative infinity, and when x tends to negative infinity, the function tends to infinity.

Answer:

Area = 1125mi

Step-by-step explanation:

Area of sector =  [tex]r^2 *\frac{\alpha }{2}[/tex]

[tex]r^{2} =5^{2} =25[/tex]

[tex]25*\frac{\alpha}{2}[/tex]

[tex]25*\frac{90}{2} =25*45=1125[/tex]

[tex]\alpha[/tex] = angle

Using the t-distribution, the 98% confidence interval for the mean of the population is (99.21, 110.79).

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

Researching the problem on the internet, the data-set is given as follows:

104, 102, 103, 105, 125, 106, 107, 110, 110, 95, 108, 86, 112, 101, 101.

The parameters are given as follows:

[tex]\overline{x} = 105, s = 8.54, n = 15[/tex].

The critical value, using a t-distribution calculator, for a two-tailed 98% confidence interval, with 15- 1 = 14 df, is t = 2.6245.

Hence the bounds of the interval are:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 105 - 2.6245\frac{8.54}{\sqrt{15}} = 99.21[/tex]

Answer:

C

Step-by-step explanation:

The sum of Sonya's 5 initial tests = 89*5 = 445.

445 + 95 = 540 (sum of the 6 tests)

Average = 540/6 = 90

Hence C

Answer:

C.  90.00

Step-by-step explanation:

We find average by adding up all values in a data set and dividing by the total number of values we have

We can say that Sonya got 89 for each test (it doesn't matter what each test score exactly was--you'll see why in a second)

So, we can add up 89 five times (5 tests have occured)

*I say add up, because that's what average is, but you can find this number by multiplying 89 · 5

89 · 5 = 445

(89 + 89 + 89 + 89 + 89 = 445)

Now, we need to add up our new value: 95

445 + 95 = 540

So, we can now divide 540 (sum of all values) by 6 (total number of values)

540 ÷ 6 = 90

So, C (90.00) is her new average

The missing step in making the equation in vertex form is option D which is

Given Equation [tex]5x^{2} +30x+15=0[/tex]

Parabola in vertex form. Equation is a relationship between two or more variables which is expressed in equal to form. It is solved to find the variables.

To express the equation of a parabola in vertex form we must complete squares. The equation is given as

The first step is to factor 5 and leave space to complete the third term in the parenthesis, along with a space outside it to compensate. This should look like

Using the normal distribution, it is found that there is a 0.4038 = 40.38% probability that the person has an IQ score between 92 and 108.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 100, \sigma = 15[/tex].

The probability that the person has an IQ score between 92 and 108 is the p-value of Z when X = 108 subtracted by the p-value of Z when X = 92, hence:

X = 108:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{108 - 100}{15}[/tex]

Z = 0.53

Z = 0.53 has a p-value of 0.7019.

X = 92:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{92 - 100}{15}[/tex]

Z = -0.53

Z = -0.53 has a p-value of 0.2981.

0.7019 - 0.2981 = 0.4038.

0.4038 = 40.38% probability that the person has an IQ score between 92 and 108.
