Genrish500 [490]

Answer:

48 cm

Step-by-step explanation:

The surface area of an object will be all of it's side area's added up.

Looking at this, we can see that there are 4 sides with side lengths 2 and 5, and 2 with side lengths 2 and 2.

The area of a rectangle is it's length times width.

$2 \cdot 5 = 10$

Since there are 4 of these sides:

$10\cdot4 = 40$ .

$2\cdot 2 = 4$

Since there are two of these sides:

$4 \cdot 2 = 8$ .

$40 + 8 =48$

Hope this helped!

Chips Ahoy wants to perform a study to determine the number of chocolate chips in their cookies. To that end, they collected a s

Dahasolnce [82]

The formula for the confidence interval is given by

Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]

We have:
Sample mean = 23.95
n = 40
σ = 2.55
z* for 99% confidence = 2.58

Substitute these values into the formula, we have

23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91

So the lower interval is 22.91 and the highest interval is 24.99
