Jackson says has an odd number of model cars.he has 6 cars on one shel and 8 cars on another shelf.is jackson correct?explain

grigory [225]

No. It's rather simple, down to addition. Ask yourself, what does 6 + 8 equal? 6 + 8 = 14. Now is this an odd number? No, 14 is an even number.

I hope this helps! If not I'm sorry.

15 points! The data set shows the weights of pumpkins, in pounds, that are chosen for a photograph in a farming magazine. The re

Answer:

Step-by-step explanation:

a). Mean of the given data set = $\frac{32+28+18+40+22}{5}$

= 28

b). x $x-\overline{x}$ $(x-\overline{x})^2$

32 32-28 = 4 16

28 28 - 28 = 0 0

18 18 - 28 = -10 100

40 40 - 28 = 12 144

22 22 - 28 = -6 36

$\sum({x-\overline x})^2$ = 296

c). Standard deviation = $\sqrt{\frac{\sum (x-\overline{x})^2}{n}}$

= $\sqrt{\frac{296}{5} }$

= 7.69

d). Mean of the new set of weights = $\frac{32+33+34+35+36}{5}$

= 34

Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).

The population of fish in a pond from 2001 to 2014 is modeled by the function below where t is the years since 2001. using the f

tresset_1 [31]

Given :

The population of fish in a pond from 2001 to 2014 is modeled by the function below where t is the years since 2001.

$p(t) = \dfrac{1125}{1+12e^{-0.17t}}$ ...1)

To Find :

Find the number of fish is the pond in 2014.

Solution :

Number of years, t = 2014 - 2001 = 13.

Putting value of t in equation 1), we get :

$p(t) = \dfrac{1125}{1+12e^{-0.17\times 13}}\\\\p(t) = 485.67$

p(t) ≈ 486

Therefore, number of fish in the pond in 2014 is 486.

Hence, this is the required solution.

Write a formula to help Jaheed determine the

agasfer [191]

Answer:

n=m(x)

Step-by-step explanation:

n is the dependent variable m is the independent variable.

how many cartons, depends on how many liters are in a carton.

how many he needs to buy= the amount in carton× how ever much is in his recipe

for example

if they're are let's say 1.5 liters per carton than m=1.5. and if he needs 15 liters than n= 15

than the equation is

$15 = 1.5 \times x$

x is how many cartons he needs to buy

solve for x by dividing both sides of the equation by 1.5

$15 \div 1.5 = x$

and x=10 in this scenario
