Thicknesses at different point are: <span>41, 38, 36, 29, 34, 44, 46, 43, 35, 40

In increasing order: 29, 34, 35, 36, 38, 40, 41, 43, 44, 46

Median = (38+40)/2 = 39m</span>

Median thickness is 39m

Answer:

Median=39m

Step-by-step explanation:

It is given that the data set is in the form of the 10 locations on the glacier, so these are:

41, 38, 36, 29, 34, 44, 46, 43, 35, 40

In order to find the estimated median thickness of the entire glacier, we need to arrange the given data set in ascending order.Thus,

29, 34, 35, 36, 38, 40, 41, 43, 44, 46

Therefore, the median is:

$M=\frac{38+40}{2}$

$M=\frac{78}{2}$

$M=39m$

Thus, the estimated median thickness of the entire glacier is 39m.

One possible inequality would be

If you subtract any year after he stepped down from 1999, the year he stepped down, the result will be a negative number.

A sports club needs to raise at least $500 by selling chocolate bars for $2.50 each. Sebastian wants to know how many chocolate

mario62 [17]

Answer:

The inequality should be written as $2.50 times c is greater than or equal to c.

Step-by-step explanation:

First, identify what you know:

1) Each chocolate bar is $2.50

2) Sebastian needs to raise at least $500

So, Sebastian needs to sell at least enough chocolate bars to hit $500. The inequality cannot be written as less than or equal to, because he can't sell less than the number of chocolate bars needed to make $500.

Automatically, I can calculate the minimum number of bars he'll need to sell.

500/2.50 = 200 chocolate bars minimum

c must equal greater than or equal to $500, for Sebastian to raise enough money! So, basically Sebastian has to sell 200 bars OR more.

Hope this helps! :)

Select the correct answer

Answer: C.156

Step-by-step explanation:

Given: Total seashells = 160

mean = 120

population standard deviation = 26 grams

The probability that the seashells weigh at least 68 grams :-'

$P(X\geq68) =P(\dfrac{x-\mu}{\sigma}\geq\dfrac{68-120}{26})\\\\=P(z\geq-2)\\\\=P(z$

Total seashells weigh at least 68 grams = 0.9772 x 160 = 156.352≈ 156

Hence, the correct option is C.156
