Record the product. use expanded form to help 5×923

1 answer:

3 0

Expanded form of 5 is 5
Expanded form of 923 is 9 hundreds + 2 tens + 3 ones
So, (5 * 900) + (20 *5) + (3 * 5) = 4500 + 100 + 15 = 4615

How would I solve this problem?

Pani-rosa [81]

I’d divide the fraction so 7 divided by 9, and then times that number by 81 to get 63 copies, 63 copies where sold yesterday.

Problem 7.1 (10 points) Let pXnqn"0,1,... be a Markov chain with state space S " t1, 2, 3u and transition probability matrix P "

Answer:

The responses to the given can be defined as follows:

Step-by-step explanation:

For point a:

fixing probability vector that is $W = [a b c]$

$\therefore$

relation: $WT =W$

$\to 0.5a+0.3b+0.2c=a ..................(1)\\\\ \to 0.4a+0.4b+0.3c=b..............(2)\\\\ \to 0.1a+0.3b+0.5c=c.................(3)$

solving the value:

$a=0.3387 \\\\ b=0.3710\\\\ c=0.2903$

Therefore the stationary distribution $\pi =[0.3387 \ 0.3710\ 0.2903]$

For point b:

$\pi$ will be limiting distribution if $\pi_j=\lin_{n\to \infity} (X_n=\frac{j}{X_0}=i) \Sigma_{\sqrt{j}} n_j=1$

$\pi$ satisfies the above condition so, it is limiting the distribution.

a nutrition major at wright state was studying the relationship between carbohydrates (x) and calories (y). for example, a servi

VLD [36.1K]

Answer:

The predicted calories would be 403 calories.

Step-by-step explanation:

We have a linear regression model relating y: calories with x: carbohydrates, which has a slope of 4.0 and a y-intercept of 3.0.

Then, the model equation is:

$y=4.0x+3.0$

With these model we can predict the calories values for any amount of carbohydrates, within the interval within which this model is valid.

If a new food is tested, and the number of carbohydrates (x) is 100, the predicted value will be:

$y(100)=4.0(100)+3.0=400+3=403$

The predicted calories would be 403 calories.

a population of insects increases at a rate of 1.5% per day about how long will it take to double A)2.5 days b) 5.0 days c) 46.6

ANTONII [103]

We can use population formula

$P(t)=P_0(1+r)^{t}$

we are given

interest rate is 1.5% per day

so,

$r=0.015$

now, we can plug values

$P(t)=P_0(1+0.015)^{t}$

$P(t)=P_0(1.015)^{t}$

we are given

P(t)=2Po

we can plug it

$2P_0=P_0(1.015)^{t}$

we can solve for t

$2=(1.015)^{t}$

$t=46.55$

so,

number of days is 46.5..........Answer
