Alright always do PEMDAS (parenthesis, exponents, multiplication and division, and addition and subtraction)!

So do what's in the parenthesis first! So 3+[1-2(-2)]

Now the brackets are kinda like another pair of parenthesis, just the second round. So do that next. 3+(-3)

Now just add/subtract to get your answer, 0!

Hope that helps!

Joaquin and Trisha are playing a game in which the lower median wins the game. Their scores are shown below. Joaquin's scores: 7

alekssr [168]

Answer:

Step-by-step explanation:

Given

Joaquin's score is $75,72,85,62,58,91$

and Trisha's score is $92,90,55,76,91,74$

Arranging score in order of value we get

Joaquin's : $58,62,72,75,85,91$

Trisha's : $55,74,76,90,91,92$

as no of values is even therefore their median is

Joaquin's $=\frac{72+75}{2}=73.5$

Trisha's $=\frac{76+90}{2}=83$

Therefore median of Joaquin's is lower

Thus Joaquin wins the game

Mars is extremely far from the Earth. Scientists estimate that it could take astronauts 245 days to travel from Earth to

Ksivusya [100]

Answer:

Step-by-step explanation:

We would liken the given scenario to distance speed and time relationship. The formula for determining average speed is

Total Distance/ total time

Since the distance between Earth and Mars is 108 million miles(108 × 10^6) the trip takes 245 days, then on average, the number of miles that the astronauts would travel each day would be

108 × 10^6/245 = 440816 miles per day

Writing in powers of 10, it becomes 4.4 × 10^5 miles per day

Rounding to the nearest whole number, it becomes 4 × 10^5 miles per day

Which of the following is true of the data represented by the box plot

zmey [24]

Answer:

The data is skewed to the bottom and contains an outlier.

Step-by-step explanation:

1. Test for outlier

An outlier is a point that is more than 1.5IQR below Q1 or above Q3.

IQR = Q3 - Q1 = 74 - 51 = 23

1.5 IQR = 1.5 × 23 = 34.5

51 - 15 = 36 > 1.5IQR

The point at 15 is an outlier.

2. Test for normal distribution

The median is not in the middle of the box.

Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.

3. Test for skewness

The longer part is to the left of the median, so the data is skewed left.

If 55% people in a city like Cricket, 30% like Football and the remaining like nother games, then what per cent of the people li

labwork [276]

$\large{\dag\:{\underline{\underline{\frak{\pmb{\red{Answer:-}}}}}}}$

Cricket = 55%
Football = 30%
Other games = Remaining (?)

So, the percent of people who like other games equals:

= 100 – (55 + 30)

= 100 – 85

= 15%

If the total no. of. people is 60,00,000:

★ Cricket

= 60,00,000 × 55/100

= 33,00,000

★ Football

= 60,00,000 × 30/100

= 18,00,000

★ Other sports

= 60,00,000 × 15/100

= 9,00,000
