Part 1:

D) 2 2/4

point B is in between the 3 and the half-point of 2. Which is 3/4 of 2.

3/4 + 2 = 2 3/4

Part 2:

C) the 12th day

It will be when Matt has his 2nd quiz and Meg will have her 4th quiz.

6 x 2 = 12

3 x 4 = 12

(it could also be the 6th day [A)] when Matt has his first quiz and Meg has her second quiz)

Ali Clara and Shane raise money for new books for the school library all Ellie rays 20% more than Clara and $58 more than Shan C

Vikki [24]

Answer:

a. $435

b. 33.33%

Step-by-step explanation:

P.S - The exact question is -

Let Clara raised money = x

As given,

Ali raised 20% more than Clara

⇒Ali raised money = $x + \frac{20}{100}x = x + \frac{1}{5} x = \frac{6}{5}x$

Also given,

Clara raised $\frac{1}{4}$ times more than Shan

Clara raised money = Shan raise money + $\frac{1}{4}$ times shan raired money

⇒Clara raised money = $\frac{5}{4}$ Shan raised money

⇒Shan raised money = $\frac{4}{5}$ times Clara

⇒Shan raised money = $\frac{4}{5}$ x

As given,

Ali raised $58 more than shan

⇒ $\frac{6}{5}x = \frac{4}{5}x + 58$

⇒ $\frac{6}{5}x -\frac{4}{5} x = 58$

⇒ $\frac{2}{5}x = 58$

⇒x = (29)(5) = $145

∴ we get

Clara raised money = x = $145

Ali raised money = $\frac{6}{5}x$ = $174

Shan raised money = $\frac{4}{5}$ x = $116

a.)

Total raised money = $145 + 174 + 116 = $435

b.)

Percentage of money Clara raised = $\frac{145}{435}$ ×100% = $\frac{1}{3}$ ×100% = 33.33%

The common difference in an arithmetic sequence is –2 and the first term is 47. What is the 29th term?

BlackZzzverrR [31]

An arithmetic sequence is an ordered list of numbers where the next number is found by adding on to the last number (ex: 2,5,8,11... is a sequence where 3 is added on to find the next number).

The equation for an arithmetic sequence is
$A_{n}=A_{1}+(n-1)d$

$A_{n}$ is the "n-th" number in the sequence (ex: is the first term in the sequence)
d is the number you add (common difference) to find the next number
The first number in the sequence is 47 so $A_{1}=47$
d=-2 because the question gives you that

$A_{n}=A_{1}+(n-1)d$
 $A_{29}=47+(29-1)(-2)$
 $A_{29}=47+(28)(-2)$
 $A_{29}=47+-56$
 $A_{29}=-9$

The answer is A. -9.

 

The answer is C. 158

For the second one, it gives you $A_{1}=4$ and $A_{}=18$
You can use this to find d

 $A_{n}=A_{1}+(n-1)d$
 $A_{3}=4+(3-1)d$
 $18=4+(3-1)d$
 $18=4+2d$
 $14=2d$
 $7=d$

Now you can just solve using the equation normally.
 $A_{n}=A_{1}+(n-1)d$
 $A_{23}=4+(23-1)(7)$
 $A_{23}=4+(22)(7)$
 $A_{23}=4+154$
 $A_{23}=158$

The answer is C. 158

you are rolling a 10-sided die with sides numbered 1-10. you keep rolling the die until you roll a prime number and then stop. l

evablogger [386]

The formula for E(x) would be SUM[ X(n)P(n)] from n = 1 to n = infinity until we get the prime number

In the given problem, a 10-sided die with 1-10 numbers is rolled until we get a prime number

Prime numbers between 1-10 = 2,3,5,7 (4 prime numbers)

Non - prime numbers = 1,4,6,8,9,10( 6 non-prime number)

Let X be the number of times the die is rolled

The probability of getting a prime =

$P(Prime) = \frac{4}{10}$

Now, the value of

E(X)=∑x.P(x) [ x-> {1, infinity}]

= P(1)X(1) +P(2)X(2)+P(3)X(3)+P(4)X(4)........+ P(n)X(n)

= 1. $\frac{4}{10}$ + 2. $\frac{6}{10}$ . $\frac{4}{10}$ + 3. $\frac{6}{10}$ . $\frac{6}{10}$ $\frac{4}{10}$ + 4. $\frac{6}{10}$ . $\frac{6}{10}$ . $\frac{6}{10}$ . $\frac{4}{10}$ .......

Hence, this is the value of E(x)
