Check the picture below.

notice the tickmarks, is a given, that those sides are congruent.

now, look at the side at the bottom, the BC side, is really shared by both triangles, and therefore, the same length for both. Meaning we might as well put a tickmark on that one too.

so the triangles are congruent because all sides are equal on each, that is $\bf \boxed{S}ide\qquad \boxed{S}ide\qquad \boxed{S}ide$

Answer:

The z-score for the trainee is of 2.

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.

The mean of the test scores is 72 with a standard deviation of 5.

This means that $\mu = 72, \sigma = 5$

Find the z-score for a trainee, given a score of 82.

This is Z when X = 82. So

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

$Z = \frac{82 - 72}{5}$

$Z = 2$

The z-score for the trainee is of 2.

I need help with all these, I don't understand.

TEA [102]

Step-by-step explanation:

first take an inequality .remove the inequality sign and then draw its graph .

now put the value x=y=0 in the inequality equation to check if its within the graph .if it satisfies the eqn then shade that part of the line which has the origin in it .similarly do for other inequalities.

you will/may get a polygon .it may be bounded or not. now by fundamental theory of lpp, obtain the terminal points

and get the values of x and y. calculate the respective value of fx and find the maximum and minimum of them .the answer will be the respective x and y values.

you can comment me to do a sum of other questions

Bruno was given $2000 at birth. His parents invested it at a 2% interest rate compounded

inysia [295]

Answer:

Step-by-step explanation:

Step one

given data

principal=$2000

rate = 2%= 0.02

time t= 13 years

Required

the final amount in the account

Step two:

A=P(1+r)^t

A=2000(1+0.02)^13

A=2000(1.02)^13

A=2000*1.294

A=$2588

Bruno will have in the account when he turned 13, $2588

Which relation is a function?

weqwewe [10]

Answer:

The vertical parabola(see attachment)

Step-by-step explanation:

The relation that is a function must pass the vertical line test.

The vertical parabola will pass the vertical line test.

This means that, a vertical line drawn across the entire graph will intersect the vertical parabola at only one point.

The horizontal parabola, the circle and the vertical line will not pass the vertical line test.

This means that, a vertical line drawn across the entire graph will intersect the graph of these functions at more than one point.
