10 = 80/8

5 1/8 = ((5x8)+1)/8 = 41/8

(80-41)/8 = 39/8

39/8 = 4 7/8

10 - 5 1/8

Convert 5 1/8 into an improper fraction.

We do this by multiplying the denominator to the whole number and adding it to the numerator, and wee keep the denominator.

8 * 5 = 40 + 1 = 41/8

10 - 41/8

Convert 10 to a denominator of 8:

10 * 8 = 80
1 * 8 = 8

80/8 = 41/8

Subtract the numerators together and keep the denominator:

39/8

Convert to a mixed number:

4 7/8

The data for numbers of times per week 20 students at Stackamole High eat vegetables are shown below:
Step2247 [10]

The dot plot uses dots to for data representation.

  • <em>The dot plot is right skewed</em>
  • <em>There is an outlier, 9.</em>
  • <em>The best measure of center is median</em>

<u>(a) The description</u>

From the dot plot (see attachment), we have the following observations,

  • <em>There are more data at the left-hand side, than the right-hand side of the dot plot.</em>
  • <em>There is only one data element at the right-hand side</em>

<em />

This means that the dot plot is right skewed

<u>(b) Outlier</u>

From the dot plot, we can see that 9 is relatively far from the other data elements.

This means that 9 is outlier

<u>(c) Measure of center</u>

In (b), we established that the dot plot has an outlier.

When there is an outlier, the best measure of center to use is the median.

<em>Hence, the median will be used as the measure.</em>

The formula for finding the sum of a finite geometric series is
S_n = a_1( \frac{1-r^n}{1-r} )

n = 17, a_1 = 3, r = 2

Substitute into the formula and you get 393213

A population numbers 15,500 and grows at 3.75% per year. Write an exponential model for the growth of this population.
krek1111 [17]

Answer: f(x)=15500(1.0375)^x

Step-by-step explanation:

The exponential model for growth is given by :-

f(x)=A(1+r)^x, where A = initial value , r = growth rate (in decimal), x = time  (in years).

Given: A= 15,500      r= 3.75% = 0.0375

The exponential model for the growth of this population will be :

f(x)=15500(1+0.0375)^x\\\\\Rightarrow\ f(x)=15500(1.0375)^x

hence, the required model: f(x)=15500(1.0375)^x

A pair of dice are rolled. What is the probability of rolling 6 or less?
Allushta [10]

Answer:

1/36

Step-by-step explanation:

The probability of rolling a number less than 6 or 6 itself on one die is 1/6. A pair of dice would be the combined probability 1/6*1/6 which is 1/36. So there's a 1/36 chance of having both dice roll numbers less than 6 or 6 itself.

Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and
FinnZ [79.3K]

Answer: Degree of polynomial (highest degree) =4

Maximum possible terms =9

Number of terms in the product = 5

Step-by-step explanation:

A trinomial is a polynomial with 3 terms.

The given product of trinomial: (x^2 + x + 2)(x^2 - 2x + 3)

By using distributive property: a(b+c+d)= ab+ac+ad

(x^2 + x + 2)(x^2 - 2x + 3)=(x^2 + x + 2) x^2+(x^2 + x + 2) (-2x)+(x^2 + x + 2)(3)\\\\=x^2(x^2)+x(x^2)+2(x^2)+x^2 (-2x)+x (-2x)+2 (-2x)+x^2 (3)+x (3)+2 (3)\\\\\\=x^4+x^3+2x^2-2x^3-2x^2-4x+3x^2+3x+6

Maximum possible terms =9

Combine like terms

x^4+x^3-2x^3+3x^2-4x+3x+6\\\\=x^4-x^3+3x^2-x+6

Hence, \left(x^2\:+\:x\:+\:2\right)\left(x^2\:-\:2x\:+\:3\right)=x^4-x^3+3x^2-x+6

Degree of polynomial (highest degree) =4

Number of terms = 5
