CAN SOMEONE PLEASE HELP ME!!!!

Mathematics
1 answer:
steposvetlana [31]3 years ago
6 0

Answer:

Step-by-step explanation:

a) Five tests: 85,85,60,62 and 59

Mean = average

= (85+85+60+62+59)/5

= 351/5

Mean  = 70.2

Median = middle number (order from least to greatest)

59 , 60, 62, 85, 85

Median = 62

Mode = the ones repeated more often = 85

b) Since mode is the highest score, compare to mean and median.

So mode is the best supports  Rolinda's claim that she is doing well in her Spanish class

c) Rolinda's claim is misleading because her first two tests were 85 but then it started decreasing each test after.

andreev551 [17]

Answer:

zero point three two meter

Step-by-step explanation:

Given

Measurement = 0.32\ meter

Required

How should it be pronounced

From the measurement above, we can see that it contains a decimal point.

Using the rules of decimal point,

The number before the decimal point will be treated as 1 number and will be pronounced as such.

While numbers after the decimal will be treated as individual digits and will be pronounced individually.

Hence, the pronunciation of 0.32 meter is zero point three two meter

Is this answer right?
lubasha [3.4K]

Solve using the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .

3(8 - 2) + 4 = 22

Parentheses...

(15 - 6)² ÷ 3 - 3³

15 - 6 = 9

(9)² ÷ 3 - 3³

Exponent....

9² ÷ 3 - 3³

In this case you have two exponents. Always apply the steps from left to right

9² ÷ 3 - 3³

9² = 81

81 ÷ 3 - 3³

3³ = 27

81 ÷ 3 - 27

Division...

81 ÷ 3 - 27

81 ÷ 3 = 27

27 - 27

Subtraction...

27 - 27 = 0

0

<u>Your mistake: </u>

You subtracted 3 - 27 before dividing 81 by 3. Remember that according to the rules of PEMDAS division must come before subtraction

Hope this helped!
