Answer:

The second one is 81300, The third one is 294

Step-by-step explanation:

Question 2

x*5*25*4/5, if x = 813

813*5*25*4/5

4065*25*4/5

101625*4/5

406500/5

81300

Question 3

3(x + 9) - 2(x + 4), if x = 275

3(275 + 9) - 2(275 + 4)

3(284) - 2(279)

852 - 558

294

The third and the fourth picture are the same problem, right?

Hope this helped you!!

suppose that during one period of extreme cold the average daily temp decreased 1 1/2 Fahrenheit each day how many days did it t

Nina [5.8K]

Answer:

The temperature decreased by 9 °F in <u>6 days.</u>

Step-by-step explanation:

Let the number of days it takes for the temperature to decrease by 9 °F be $x$ .

Given:

Average daily temperature decreases by $1\frac{1}{2}$ °F.

Decrease of temperature in 1 day = $1\frac{1}{2}$ = 1.5 °F.

∴ Decrease in temperature in x days is $1.5x$ .

Now, as per question, decrease in temperature in 'x' days is 9 °F.

Therefore, $1.5x=9$

$x=\frac{9}{1.5}$

$x=6$

Therefore, the temperature decreased by 9 °F in 6 days.

Find the value of y. -6y+14+4y=32

Hunter-Best [27]

Answer:

So first subtract 14 from 32

That means that -6y+4y = 18

Simplify the left side 4-6=-2

-2y = 18

Divide by -2

Suppose that 45% of students in a college have a smart phone. If you select three students at random, what is the probability th

Sidana [21]

Answer:

$P(X=3)$

And we can use the probability mass function and we got:

$P(X=3)=(3C3)(0.45)^3 (1-0.45)^{3-3}=0.091$

Then the probability that all three have a smart phone is 0.091

Step-by-step explanation:

Let X the random variable of interest "number of students with smartphone", on this case we now that:

$X \sim Binom(n=3, p=0452)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(X=3)$

And we can use the probability mass function and we got:

$P(X=3)=(3C3)(0.45)^3 (1-0.45)^{3-3}=0.091$

Then the probability that all three have a smart phone is 0.091
