<u>Answer:</u> The given statement is true.

<u>Step-by-step explanation:</u>

Significant figures are defined as the figures that are present in a number. It expresses the magnitude of a quantity to a specific degree of accuracy.

There are some rules to detect the significant figures in a number:

  • All digits ranging from 1 to 9 are always considered significant.
  • Every non-zero number is always considered significant. For example, 274, 2.74, and 27.4 all have three significant figures.
  • All zero’s that are present between the integers is always considered significant. For example, 5007, 5.007, and 50.07 all have four significant figures.
  • All zero’s preceding the first integer is never considered significant. For example, 0.0089 has two significant figures.
  • All zeros that are present after the decimal point are always significant. For example, 4.800, 48.00, and 480.0 all have four significant figures.

<u>Rule applied when numbers are added or subtracted:</u>

The number having less number of significant figures after the decimal point will determine the number of significant figures in the final answer.

Hence, the given statement is true.

vova2212 [387]

Answer:

juliet collected 50 cans

Step-by-step explanation:

let x be rosanas cans

10+x+2x = 130

simplify

10 + 3x = 130

3x = 130 - 10 = 120

x = 120/3 = 40

rosanas cans = 40

juliets cans = 40 +10 = 50

santiagos cans = 50 x 2 = 100

but i think the question is wrong!!

Find the length of BC
bazaltina [42]

Answer:

BC = 19.78

Step-by-step explanation:

using sin(x) rule

sin(54)= 16/BC

sin(54)=0.80

∴0.80=16/BC  (divied both side by 0.80)

BC=16/0.80 =19.78

Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed w
cupoosta [38]

Answer:

The cutoff sales level is 10.7436 millions of dollars

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 12, \sigma = 1.2

15th percentile:

X when Z has a pvalue of 0.15. So X when Z = -1.047.

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

-1.047 = \frac{X - 12}{1.2}

X - 12 = -1.047*1.2

X = 10.7436

The cutoff sales level is 10.7436 millions of dollars
