How many times greater is the digit in the tenths place than in the hundredths place?

zhannawk [14.2K]

That depends on what the digits are. It could be anywhere between zero times and infinite times. If both are the same digit and not zero, then the tenth is ten times the size of the hundredth.

According to police sources, a car with a certain protection system will be recovered 87% of the time. Find the probability that

WITCHER [35]

Answer: 0.01145

Step-by-step explanation:

We use Binomial distribution , where the probability of getting x successes in n trial is given by :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , p = probability of getting each success in each trial.

As per given

The proportion that a car with a certain protection system will be recovered= p=0.87

n= 8

Let x be the number of cars will be recovered.

Then, the probability that 4 of 8 stolen cars will be recovered:

$P(X=4)=^8C_4(0.87)^4(1-0.87)^{8-4}$

$=\dfrac{8!}{4!(8-4)!}(0.87)^4(0.13)^4\\\\= 70(0.57289761)(0.00028561)\\\\=0.0114537700474\approx0.01145$

Hence, the required probability is 0.01145.

A printer will produce Katie wedding invitations for $210. The price to produce 120 invitations is $290. The printer uses a line

VMariaS [17]

Thank you for asking this question. Here is your answer:

M = y2 - y1/x2 - X1 = M

= 290 - 210/120 - 80

M = 80/40

M = 2

Now we will consider y intercept

y = mx + b

210 = 2(80) + b

210 = 160 + b

b = 210 - 160

= 50

Now we will combine everything in order to get the answer.

y = 2x + 50

y = 2(60) + 50

y = 120 + 50

y = 170

So the final answer for this question is $170.

If there is any confusion please leave a comment below.
