Two or an ext decimal number are claimed to be indistinguishable decimals, once they name the very same value (or very same amount). Because that example, the decimals: 0.2 = 0.20 = 0.200 = 0.2000 etc. For this reason by successive enhancement of zeros ~ the decimal part of the number ~ the decimal point method the same number and hence are equivalent. Therefore, the decimals: 5.3, 5.30, 5.300, 5.3000 etc are all equivalent.

You are watching: Two decimals that are equivalent to 5.300

1.

Step-by-step explanation: - (-3) need to be a optimistic 3 once simplified. Whenever over there is two negative sign in front of a number the is going to be positive.

Do friend think it"s possible to have two data sets where just one has actually an outlier, however the other has a greater standard deviation?

yellowcomic.com:Yes. The traditional deviation is the square root of the variance, and the variance is the mean of (distance from the mean) squared.

Step-by-step explanation:

Emergency rooms have actually reason to suspect that visits rise on the weekends. A current report suggests that Monday with Thurs

No the facility dose not have the very same pattern as the current report at the 10% level

Step-by-step explanation:

To recognize if the Facility have actually the very same pattern ; Perform Chi squared test because that Goodness of right

state the theory

H0 : μ = very same pattern

Ha : μ ≠ same pattern

expected frequency ( E ) = relationship * summation the frequency

summation that frequency = 1000

degree of freedom = 7 - 1 = 6

Next : calculation the meant frequency (E) , (O-E)²/E. Offered that the observed frequency and expected proportion is provided

For Monday

expected frequency = ratio * frequency = 0.1 * 1000 = 100

(O-E)²/E. = ( 120 - 100 )^2 / 100 = 4.0.

it was observed frequency ( O ) , meant frequency ( E )

For Tuesday

E = 0.1 * 1000 = 100

(O-E)²/E = ( 130 - 100 )^2 / 100 = 9.0

Repeat exact same calculations because that Wednesday with Sunday

Then carry out Chi-squared check

X² = Σ(O-E)²/E = 63.642

∝ = 0.1

df = 6

hence P-value = 0.000 ( =chisq.dist.rt(test-stat,df)

since P-value 7 0

Step-by-step explanation:

Let x stand for the amount that Andre"s neighbor salary him every week to mow the lawn.

Andre constantly gives a \$2 donation come the food financial institution in weeks once he earns money. Since it will take him 5 main to earn the money for his dad"s gift, his complete donation because that 5 weeks will certainly be 2×5 = \$10

Andre wants to save \$40 to buy a gift for his dad. It way that the amount the he gets paid because that mowing the lawn - his complete donations in 5 mainly = the amount the he wants to save. Therefore,

x - 10 = 40

x = 40 + 10 = \$50

5 0

i think it"s the very first option due to the fact that the others make no sense

6 0
