A car cost $10.38 per 100 miles to drive, while car B $6.64 per 100 miles to drive. How much more would car A cost to drive 550 miles?

Answer:

The answer is A: mode

Step-by-step explanation:

The mode is what data occurs the most. The more popular data would occur more

Explanation:

20 people play cricket, 8 of them play both, so 20-8 = 12 people play cricket only.

14 play football, 8 play both, so 14-8 = 6 play football only

We have,

So far, this tallies to A = 12+6+8 = 26 people who play one sport only, or both sports mentioned. Now add in the four people who play neither sport and we get to B = 26+4 = 30 students overall.

The probability of selecting someone who plays at least one of the two sports mentioned is A/B = 26/30 = (13*2)/(15*2) = 13/15

This is effectively saying: if we had 15 students, then 13 of them play at least one of the two sports mentioned.

Answer:

f(x)=x^2+4x-21

Step-by-step explanation:

Answer:

f(x) = (x + 7)  (x - 3)

Step-by-step explanation:

f(x)=(x+[tex]2)^{2}[/tex]-25

(x + 7) (x - 3) we put the 2 x's because of the (x+2)^2

now the + 7 and - 3, multiply the 2 numbers = -21 then use those 2 in

(x+2)^2 to add for the answer = -25

Answer:

x = 40

Step-by-step explanation:

x/2 = 20

x/2(2) = 20(2)

x = 40

Answer:

240 mi^3

To explain what 27 times 13 means, look at it as 27 added together 13 times. To get the answer, you could just write down the number 27, 13 times and then add the 27 numbers together.

If you have one of those old-fashioned handheld calculators, you can double check that the answer is 351 by pressing 27, then x, then 13, and then = to get the answer.

Answer:

[tex]351[/tex]

Step-by-step explanation:

[tex]27\times \:13[/tex]

Step 1: Line up the numbers; Multiply the top number by the bottom number one digit at a time starting with the ones digit (from right to left)

[tex]\begin{matrix}\space\space&2&7\\ \times \:&1&3\end{matrix}[/tex]

Step 2: Multiply the top number by the bolded digit of the bottom number

[tex]\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}[/tex]

Step 3: Multiply the bold numbers; Carry 2 to the column on the left and write 1 in the result line

[tex]7\times \:3=21\\\\\frac{\begin{matrix}\space\space&2&\space\space\\ \space\space&2&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&\space\space&1\end{matrix}}[/tex]

Step 4: Add the carried number to the multiplication

[tex]2+2\times \:3=8\\\\\frac{\begin{matrix}\space\space&\textbf{2}&\space\space\\ \space\space&\textbf{2}&7\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]

Step 5: Multiply the top number by the bolded digit of the bottom number

[tex]\frac{\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]

Step 6: Multiply the bold numbers

[tex]7\times \:1=7\\\\\frac{\begin{matrix}\space\space&\space\space&2&\textbf{7}\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&\space\space&7&\space\space\end{matrix}}[/tex]

Step 7: Multiply the bold numbers

[tex]2\times \:1=2\\\\\frac{\begin{matrix}\space\space&\space\space&\textbf{2}&7\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&2&7&\space\space\end{matrix}}[/tex]

Step 8: Add the rows. Add zero for simplicity

[tex]\frac{\begin{matrix}\space\space&\space\space&2&7\\ \space\space&\times \:&1&3\end{matrix}}{\begin{matrix}\space\space&0&8&1\\ \space\space&2&7&0\end{matrix}}[/tex]

[tex]81 + 270 = 351[/tex]

Therefore 27 times 3 is 351

Answer:

Step-by-step explanation:

This is a composite function, in which we will first evaluate the s function at a value of 2, then we will use that value in the t function.

s(2) = 5(2)+ 5 so

s(2) = 15. Now we evaluate the t function at 15:

t(15) = 3(15) + 4 so

t(15) = 49

Answer:

x = 1

Step-by-step explanation:

The line of symmetry is defined as the x value of the vertex of a parabola.

To find the vertex of a parabola, we need to convert to vertex form.

Vertex form looks like this:

[tex]y=a(x-h)^2+k[/tex], where -h is the x value of the vertex and k is the y value of the vertex.

H is also defined as [tex]\frac{-b}{2a}[/tex] where a is the coefficient of x squared and b is the coefficient of the x term.

The coefficient of the x squared term is 1 and the coefficient of b is -2.

Plugging in, we get [tex]\frac{-(-2)}{2(1)}[/tex], which is equal to 1. This can then be plugged into the equation as

[tex]y=1(x-1)^2+k[/tex], but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.

Answer:

x = 1

Step-by-step explanation:

Was the equation actually

f(x) = x² - 2x - 3

--------------------------

the line of symmetry occurs at the midpoint of the roots

factor

(x + 1)(x - 3)

x = { -1, 3}

midpoint of roots

x = (-1 + 3)/2

x = 1

line of symmetry

x = 1

Answer:

x = 1.5 +/-√3.25.

Step-by-step explanation:

x^2 - 3x - 1 = 0

x^2 - 3x = 1

Completing the square:

(x - 1.5)^2 - 1.5^2 = 1

(x - 1.5)^2 = 1 + 2.25 = 3.25

x - 1.5 = +/-√3.25

x = 1.5 +/-√3.25

Answer:

Amount of money share by Jess = £25.70

Another Amount of money share by Jess = £34.3

Step-by-step explanation:

Given:

Amount of money Jess have = £60

Sharing ratio = 3 : 4

Find:

Amount of money share by Jess

Computation:

Sharing amount = Shared ratio / Sum of ratio

Amount of money share by Jess = 60[3/(3+4)]

Amount of money share by Jess = 60[3/(7)]

Amount of money share by Jess = 180 / 7

Amount of money share by Jess = £25.70

Another Amount of money share by Jess = £60 - £25.70

Another Amount of money share by Jess = £34.3

Answer:

7 hours

Step-by-step explanation:

15 dollars +15 dollars 30 dollars=2 hours. 5 dollars left 15 divided by 3, 5 dollars. 3 divided by 3 = 1 so 1 hours is 5 dollars. My explaining is not good.

Answer: 7 hours

Step-by-step explanation:

She earns 5 dollars per hour because 5x3=15

and then you do 15x2=30

then 3x2=6

then just add 1 to 6

6+1=7

so there's your answer

7 hours

Answer:

Simplifying radicals is the process of manipulating a radical expression into a simpler or alternate form. Generally speaking, it is the process of simplifying expressions applied to radicals.

Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.

Step-by-step explanation:

The radical symbol represents the root of a number and is read as x radical n or the nth root of x.

The symbol " that expresses a number's root is known as radical, and it is read as x radical n or the nth root of x. The horizontal line that surrounds the number is known as the vinculum, and the number beneath it is known as the radicand. The index or degree is the number n written before the radical.

The process of transforming a radical expression into a simpler or alternate form is known as simplifying radicals. In general, it is the process of simplifying expressions that are applied to radicals.

Estimation (or estimating) is the process of determining an estimate, or approximation, which is a value that can be used for a specific purpose despite the fact that the input data may be incomplete, uncertain, or unstable. The value is still useful because it is based on the best available information.

Solution :

The level of significance refers to the probability of the null hypothesis that may be rejected in the study by the observer. As the sample size increases, the p value also increases but the significance remains same. When the sample size increase and becomes large, the null hypothesis can be rejected more easily.

The business decisions are taken defending the significance level of the statistical validation in cases of uncertainty. Suppose the null hypothesis is the sales after the marketing campaigning remains same. The company will launch the marketing campaign when the confidence level is 95% so that after the campaign the sales will increase. It means that the significance level must be high enough for rejecting null hypothesis of sales post of the marketing campaign that remains same.

When the sample size increases, the sensitivity of hypothesis increases, and for a large sample, the hypothesis may be rejected even though it is true.
