Answer:

The answer is the second option

Minimum = 203, Q1 =217, median = 230, Q3 = 245, maximum = 290

Step-by-step explanation:

First order the data from lowest to highest

203, 216, 217, 224, 224, 236, 245, 245 ,262 ,290

Minimun = 203

Maximum =290

Now divide the data in half

203, 216, 217, 224, 224, 236, 245, 245 ,262 ,290

Divide half of the first half of the data. The data of the medium is the first quartile

1) 203, 216, [217], 224, 224

Divide half of the second half of the data. The data of the medium is the third quartile

2) 236, 245, [245] ,262 ,290

The average between the two values that are in the center of the 10 ordered data is the median

203, 216, 217, 224, [224, 236], 245, 245 ,262 ,290

$Median =\frac{224+236}{2}=230$

Median=230

The answer is the second option

Minimum = 203, Q1 =217, median = 230, Q3 = 245, maximum = 290

Does the equation 2(x + 3) + x = 3(x + 2) have one, infinite, or no solutions? Explain how you got your answer.

11111nata11111 [884]

The equation has infinite solutions, because each side is equal to 3x + 2. Therefore, whatever variable the x replaces will give the same answer every time.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Leviafan [203]

Answer: $\bold{(A)\ a_n=500,000(1.1)^{n-1}}$

<u>Step-by-step explanation:</u>

From the data provided, we know the sequence is {500,000; 550,000; 605,000; ... }. $So, a_1 = 500,000\ and\ r = \dfrac{550,000}{500,000}=1.1$

The explicit rule for a geometric sequence is: $a_n=a_1(r)^{n-1}$

So, the explicit rule for the sequence above is: $a_n=500,000(1.1)^{n-1}$

Write an expression for the area of each shape provided. Make sure it’s in simplest polynomial form

Yuri [45]

Answer: $6x^{2} +7x-5$

Step-by-step explanation:

area of a trapezoid: a= a+b/2 H

so...

5x+7+x+3/2=6x+10/2=3x+5

then take 3x+5 and multiply it by 2x-1

soo... (3x+5)(2x-1) and I used FOIL

so then 6x^2-3x+10x-5

which is equal to 6x^2+7x-5

I hope this helps =)
