<h2>Answer:</h2>

The number of trees which are less than 20 meters are:

                                  9

<h2>Step-by-step explanation:</h2>

Based on the histogram we are asked to find the number of trees which are less than 20 meters in height.

  Class interval             Frequency

        4-8                             1

        8-12                            2

        12-16                           2

        16-20                          4

        20-24                          6

        24-28                          4

        28-32                          2

i.e. we are asked to find the  total number of tress that lie in the class interval 4-20.

i.e. we add the frequencies that lie in the interval 4-20

i.e. Number of trees= 1+2+2+4=9 trees.

The tallest living man at one time had a height of 262 cm. The shortest living man at that time had a height of 68.6 cm. Heights
AysviL [449]

Answer:

more the z-score more will be the extreme. therefore tallest man has high extreme

Step-by-step explanation:

Formula for z-score: \frac{X-\mu }{\sigma}

where

X is height of tallest man

μ mean height

σ is standard deviation

z score for tallest is

z-score = \frac{ 262 - 175.32}{8.17} = 10.60

similarly for shortest man

z-score = \frac{68.6 - 175.32}{8.17} = - 13.06

more the z-score more will be the extreme. therefore tallest man has high extreme

I also need help with this
Dimas [21]

Answer:

7 strips

Step-by-step explanation:

One way we can solve this is through guess and check. Let's start with 4 strips. If Joe's grandma makes 4 strips, she will have 0.75*4 = 3.00 yards of fabric. That's a really low amount of fabric. Let's double that to 8, where Joe's grandma would need 0.75*8 = 6.00 yards of fabric. That's really close! Let's remove one strip. 0.75*7 = 5.25 yards of fabric. Perfect! Joe's grandma can cut exactly 7 strips
