Answer: The stem-and-leaf plot is shown below in the attached image.

=============================================================

Explanation

The given data set is:

40, 27, 17, 43, 47, 33, 26, 58, 49, 48, 35

64, 61, 54, 74, 43, 83, 61, 57, 34

Let's sort the values from smallest to largest

17, 26, 27, 33, 34, 35, 40, 43, 43, 47, 48, 49, 54, 57, 58, 61, 61, 64, 74, 83

The stems are the tens digit of each value. The stems used are: 1, 2, 3, 4, 5, 6, 7, and 8. The stems will go along the first column (along the left side) in the table.

The leaves represent the units digit of each value.

For example, the value 47 has a stem of 4 and a leaf of 7. At the top or bottom of your stem-and-leaf plot, you could have a key that says "4 | 7 means 47". The vertical line indicates the separation of stem and leaf.

For each stem row, sort the leaves from smallest to largest. You should get what you see in the table below. The horizontal spacing between each leaf is optional, and I find it's handy to easily read that portion of the table. Though your teacher or math book may remove those spaces entirely.

Also optional are horizontal grid lines to separate the stems.

Three hikers are dividing the costs of a hiking trip evenly. They bought two permits that cost $15 each, three tram tickets that

cestrela7 [59]

Each hiker owes $41 or 4100 cents for the hiking trip.

Explanation

Cost of each permit is $15. So, the cost of two permits will be: $(\$15*2)= \$30$

Cost of each tram ticket is $19. So, the cost of three tickets will be: $(\$19*3)=\$ 57$

Cost of one can of bear spray is $36.

So, the total cost of the hiking trip $=\$30+\$57+\$36=\$123$

As the three hikers are dividing the total costs of the trip evenly, so each hiker owes $=\frac{\$123}{3}=\$41$ or 4100 cents.

Ms. Thomas is saving up to buy a new phone. She has already saved $200 and adding $50 per month to her saving account. She wants

melomori [17]

Answer:

Step-by-step explanation:

The inequality equation can be determined by using the concept of arithmetic progression;

a(n) = a₁ + (n-1)d

where;

a(n) = 1000

a = 200

d = 50

The inequality will be:

1000 = 200 + ( n - 1) 50

1000 = 200 + 50n - 50

1000 = 150 + 50 n

1000 - 150 = 50 n

850 = 50 n

n = 850/50

n = 17 months

So, if Ms. Thomas is planning to have more than $1000 in her account, she will need to save for 17 moths before she can buy the phone.

Ocean sunfish are well known for rapidly gaining a lot of weight on a diet based on jellyfish. The relationship between the elap

Maksim231197 [3]

Answer:

Every day, the mass of the sunfish is multiplied by a factor of [ln(1.34)/6].

Step-by-step explanation:

You have the following function:

$M(t)=(1.34)^{\frac{t}{6}+4}$

To know what is the factor that multiplies the mass of the sunfish each day, you derivative the function M(t):

$\frac{dM(t)}{dt}=(1.34)^{\frac{t}{6}+4}(\frac{1}{6})ln(1.34)\\\\\frac{dM(t)}{dt}=\frac{ln(1.34)}{6}[(1.43)^{\frac{t}{6}+4}]\\\\\frac{dM(t)}{dt}=\frac{ln(1.34)}{6}M(t)$ (1)

where you have used the following general derivative:

$g(t)=a^{f(t)}\\g'(t)=a^{f(t)}f'(t)ln(a)$

The derivative give you the increase in the mass per day (because t is days). By the expression (1) you can conclude that each day the mass increase a factor of [ln(1.34)/6].

Every day, the mass of the sunfish is multiplied by a factor of [ln(1.34)/6].

Anyone think they could help me with this question???

Slav-nsk [51]

Answer:

Step-by-step explanation:

As we can see the triangles are congruent so

< F = < C ( being corresponding angles of congruent triangle)

< C = 29

Now

<A +<B + <C = 180° { being sum of angles of triangle }

5x + 1 + 90 + 29 = 180°

5x = 180° - 120°

5x = 60°

x = 12°

<A = 5 * 12° + 1 = 61°

Hope it will help :)
