What percent is 608 million of 845 million? Round to the nearest 100th place and Enter your answer with the percent symbol.

bezimeni [28]

Answer: 72%

Step-by-step explanation: Well, we want to know what percent 608 is of 845, so to solve that, let's call 845 100%, as we're solving it terms of 845. 845 is 100%, then it follows that 8.45 is 1%.

Now we can see how many 8.45's go into 608, which comes out to 71.95266...%, which can be rounded nicely to 72%

1. Which graph models the equation y = 3.5x?

MAXImum [283]

1) is C because the line is increasing not decreasing and it goes up 7 & right 2.
2) the y-intercept is -2 and the slope is up 3 over 1, so the answer has to be B
3) the answer is A because the up 2 over 3
4) the y-intercept is a positive 4, and the slope is going down 3 and to the right 5, and the line is decreasing so you know it has to be negative. the answer is D

If the weight (in grams) of cereal in a box of Lucky Charms is N(489,6), what is the probability that the box will contain less

Wittaler [7]

Answer:

0.000064 = 0.0064% probability that the box will contain less than the advertised weight of 466 g.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

N(489,6)

This means that $\mu = 489, \sigma = 6$

What is the probability that the box will contain less than the advertised weight of 466 g?

This is the p-value of Z when X = 466. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{466 - 489}{6}$

$Z = -3.83$

$Z = -3.83$ has a p-value of 0.000064

0.000064 = 0.0064% probability that the box will contain less than the advertised weight of 466 g.

How many 5 digit numbers have the property that all their digits are ascending.

sertanlavr [38]

Answer:

So, for the ascending order, there are only 9 digits to choose from, and hence, there are 9C5 ways to choose the 5 digits. So, there can be 9C5=126 5-digit no.s with their digits in an ascending order.

Tao Bergolts bank granted him a single-payment loan of $4,400 at an interest rate of 12 percent. The term of the loan is 172 day

jolli1 [7]

Answer: $ 14736 (approx)

Step-by-step explanation:

Since, Maturity value is the amount payable to an investor at the end of a holding period of debt instrument.

And, It is defined as, $V= P(1+r)^n$

Where, P is the principal amount,

r is the interest rate

And, n is the time period.

Here, P= $4,400 r= 12 % and n = 172/365

Thus, Maturity value for this loan,

$V = 4400(1+12)^{172/365}$

⇒V= 4400 × 3.34908932078 = 14735.9930114 ≈ 14736
