From 42 acres to 72 acres (round to the nearest percent

guajiro [1.7K]

Answer:

42 acres to 72 acres, there is an increase of 30 acres

percentage wise

72-42=30

30/72=.4166...

therefore there is also a 41.6% increase

Step-by-step explanation:

71.42 Percentage change:×100%

Now, the change is given from 42 acres to 72 acres, therefore

Change= 72-42=30

⇒Percentage change= ×100%

= 71.42

which postulate or theorem, if any,could be used to prove the triangles congruent? if not enough information is given, write not

Rus_ich [418]

The ways we can prove the triangles congruent:

SAS (side, angle, side)
ASA (angle, side, angle)
AAS (angle, angle, side)
SSS (all sides equal)
RHS/HL (Right Angle-Hypotenuse-Side/Hypotenuse-legs)

In these cases:
A. <B = <E
<A = <D
AC=DF

AAS (angle, angle, side) could be used.

B. AB=ED
BC=EF
AC=DF

SSS (all sides equal) could be used.

C.<BEA=<CED (right opposite angles)

As there is only one pair of equal angles we can find,there is not enough information.

D.<B = <E
BC=CE
<ECD < ACE(right opposite angles)

ASA (angle, side, angle) could be used.

Hope it helps!

1a. [1 mark] The price per kilogram of tomatoes, in euros, sold in various markets in a city is found to be normally distributed

andrey2020 [161]

Answer:

The price that is two standard deviations above the mean price is 4.90.

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.

Mean of 3.22 and a standard deviation of 0.84.

This means that $\mu = 3.22, \sigma = 0.84$
