The isosceles triangle has two sides congruent which mean they are equal. If two sides are equal, it also means that two angles are equal.
For triangle XYZ, we have angles shown below:
∠X + ∠Y + ∠Z = 180°
If ∠Y = a°, then we can have the expression for ∠X such as shown below:
∠X + a° + ∠Z =180°
∠X= 180° - a° - ∠Z
If ∠Z = ∠Y, then we have the final expression:
∠X = 180° -2a°

Answer:
the ounces of dough did you buy is 78
Step-by-step explanation:
The number of dough ounces that should be buy is given below:
Given that
There is a requirement of 6 dough ounces and 4 sauce ounces
So for each person it would be
= 4 + 6
= 10
Now the total ounces bought is 130
So, the number of people used
= 130 ÷ 10 ounces
= 13 people
Now let us assume the number of dough ounces be x
Now if there is 6 dough ounces and there are 13 people
So, the total dough ounces purchased is
x = 6 × 13
= 78
Hence, the ounces of dough did you buy is 78
Answer:
19 = x
Step-by-step explanation:
The square of the tangent segment = The product of (whole secant segment) (the outside part of the secant segment)
BD²= (BA)(BE)
8² = (4 + x - 7) (4) BA = BE + EB
8² = (x - 3)(4)
64 = 4x - 12
64 + 12 = 4x
76 = 4x
19 = x
Considering that the subjects are chosen without replacement, they are not independent, and the probability cannot be found using the binomial distribution.
The binomial distribution and the hypergeometric distribution are quite similar, as:
- They find the probability of exactly x successes on n repeated trials.
- For each trial, there are only two possible outcomes.
- The difference is that the binomial distribution is for independent trials, that is, in each trial, the probability of success is the same, while the hypergeometric distribution is for dependent trials.
- If the sample is without replacement, the trials are not independent, thus the hypergeometric distribution is used, not the binomial.
