Answer:

Square

Step-by-step explanation:

Given

\angle 1 = x + 60

\angle 2 = 2x + 30

1 and 2 are consecutive

Required

Determine a special name to the parallelogram

For consecutive angles 1 and 2 of a parallelogram, we have:

\angle 1 + \angle 2 = 180

x + 60 + 2x + 30 = 180

3x +90 = 180

Collect like terms

3x = 180 - 90

3x = 90

x = 30

Next, is to calculate angles 1 and 2

\angle 1 = x + 60

\angle = 30 + 60 = 90

\angle 2 = 2x + 30

\angle 2= 2*30 + 30 = 90

Both angles are 90.

This implies that each angle in the parallelogram is 90.

<em>Such a parallelogram is either a rectangle or a square</em>

Answer: 615.4

Step-by-step explanation:

A=\pi r^{2}

if the radius is 14

A=\pi 14^{2} \\A=196\pi \\A=196(3.14)\\A=615.44\\

The loaves of rye bread distributed to a local store by a certain bakery have an average length of 30 centimeters and a standard
cupoosta [38]

Answer:

79.91% of loaves are between 26.94 and 32.18 centimeters

Step-by-step explanation:

When the distribution is normal, we use 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 question, we have that:

\mu = 30, \sigma = 2

What percentage of loaves are between 26.94 and 32.18 centimeters

This is the pvalue of Z when X = 32.18 subtracted by the pvalue of Z when X = 26.94.

X = 32.18:

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

Z = \frac{32.18 - 30}{2}

Z = 1.09

Z = 1.09 has a pvalue of 0.8621

X = 26.94:

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

Z = \frac{26.94 - 30}{2}

Z = -1.53

Z = -1.53 has a pvalue of 0.0630

0.8621 - 0.0630 = 0.7991

79.91% of loaves are between 26.94 and 32.18 centimeters
