Answer:

The number 3 is the stem.

The number 4 is the leaf.

Step-by-step explanation:

The Stem and Leaf Plot is a mathematical table used for the graphical representation of a data set. It involves splitting each data value into a stem (typically the first number, on the left) and a leaf (the last number, on the right).

The stem list is used for grouping data value downwards while the leaf values move rightward from its respective stem values and it's used for showing each data value within a group.

Also, the key of a stem and leaf plot is used as a guide on how to read the data set.

For example, the key for a stem and leaf plot is 3|4. Thus, the number 3 is the "stem" and the number 4 is the "leaf."

Monica [59]

Answer:

=1050 wildebeests

Step-by-step explanation:

We can form an arithmetic series for the wildebeest migration.

Sₙ=n/2(2a+(n-1)d) where n is the number of terms, d is the common difference and a is the first term.

a=24

n=20

d=3

Sₙ=(20/2)(2(24)+(20-1)3)

Sₙ=10(48+57)

=1050 wildebeests

My name is Ann [436]

The solution to the expressions given are;

9 -9t/ 12 - 5t

a. 20/ 169

b. -170/ 169

c. 386/ 169

d. -10/ 169

<h3>How to solve the expressions</h3>

Given:

$\frac{9 - 19t}{12 - 5t}$

We can see that both variables in the numerator and denominator have no common factor, thus cannot be factorized further

a. $\frac{203}{169} - \frac{183}{169}$

First, let's find the lowest common multiple

LCM = 169

= $\frac{203 - 183}{169}$

= $\frac{20}{169}$

= 20/ 169

b. $\frac{13}{119} - \frac{183}{119}$

The lowest common multiple is 119

= $\frac{13 - 183}{119}$

substract the numerator

= - 170/ 119

c. $\frac{203}{169} - \frac{183}{169}$

The lowest common multiple is 169

= $\frac{203 + 183}{169}$

= 386/ 169

d. $\frac{9}{169}- \frac{19}{169}$

The lowest common multiple is 169

= $\frac{9 - 19}{169}$

= - 10/ 169

Thus, we have the solutions to be 9 -9t/ 12 - 5t, 20/ 169, -170/ 169, 386/ 169, -10/ 169 respectively.
