Answer:

Yes, all equilateral triangles are also isosceles.

Step-by-step explanation:

An isosceles triangle has at least two sides of the triangle of equal measure and the two base angles are equal in degree measure. By definition all sides of an equilateral triangle are equal in length and all angles are equal in degree measure.

Using this info, I will say yes, all equilateral triangles are also isosceles. The correct answer would be A.) True.

A woman is randomly selected from the 18–24 age group. For women of this group, systolic blood pressures (in mm Hg) are normally
Naddik [55]

Answer:

X \sim N(114.8,13.1)  

Where \mu=114.8 and \sigma=13.1

We are interested on this probability

P(X>140)

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

And we can find this probability using the complement rule:

P(z>1.924)=1-P(z

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:

X \sim N(114.8,13.1)  

Where \mu=114.8 and \sigma=13.1

We are interested on this probability

P(X>140)

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:P(X>140)=P(\frac{X-\mu}{\sigma}>\frac{140-\mu}{\sigma})=P(Z>\frac{140- 1114.8}{2.6})=P(z>1.924)And we can find this probability using the complement rule:

P(z>1.924)=1-P(z

BRAINLIEST TO CORRECT
Masteriza [31]

Answer:

Step-by-step explanation:

So we know they had got $22,553 which is 90% more than last year. With this information we know:

190% = $22,553

1% = $22,553/190

1% = $118.70

100% = $11870

So overall it would be $11870 which they had got last year
