Kobotan [32]3 years ago

*The minimum is 39.*
the lowest recorded temperature is 39 so this is correct


*The lower quartile (Q1) is 44.*
first lets list the numbers from small to large
39, 43, 44, 44, 45, 49, 49, 50, 51,
now we need to find the median of 39, 43, 44 and 44
\frac{43 + 44}{2}  = 43.5
43.5 is the Q1 of our statics not 44


The median is 45.
again lets list the numbers from small to large
39, 43, 44, 44, 45, 49, 49, 50, 51,
median is the middle number so this is correct

The maximum is 51.
the biggest number is 51 therefore this is correct

The following shapes are similar. Set up equation and solve for the variables
koban [17]

Answer:

x=10

Step-by-step explanation:

For number 19.

The equation you get is:

X+2=6(2) this is because 5x2=10, so you have to do the same here.

so, X+2=12

-2 from both sides and you get

x=10

I need help on 5-7. Its a little confusing for me
Len [333]

Answer:

5. x = 5, y = 3

6. x = 0, y = 4

7. x = -1, y = 1

Step-by-step explanation:

5. substitute 3(value of y) into the equation y = x - 2:

=> 3 = x - 2

=> x = 5

6. substitute 0(value of x) into the equation y = x + 4:

=> y = 0 + 4

=> y = 4

7. substitute 1(value of y) into the equation y = 2x + 3:

=> 1 = 2x + 3

=> 2x = -2

=> x = -1

Two and four tenths times a number minus three is greater than one and six tenths times the number minus four and one tenth
diamong [38]

Let's first turn all the words into numbers:

Two and four tenths = 2.4

One and six tenths = 1.6

Four and one tenth = 4.1

Now lets represent "a number" as x.

Then translate the wording into a linear equation:

2.4x-3>1.6x-4.1

Simplify and isolate the variable:

0.8x>-1.1

Divide by 0.8

x>1.375 or x>1 3/8
