(a) explain why her reasoning is incorrect.

(b) estimate the square root of 50 to the nearest tenth without using your calculator.

show your work.

Jaclyn's reasoning is incorrect. 7.1 is the correct answer.

Step-by-step explanation:

Jaclyn estimates the square root of 50 in the following way:

(a) Jaclyn's reasoning is incorrect because she has taken square root of 25 and multiplied by 2 while should be equal to 5√2.

(b)

Write 50 as its prime factors.

Group the same prime factors in to pairs

rewrite each pair in exponent form

Use this rule

= 7.07 rounded to 7.1

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
