Find the area of the composite figure.

===========================================================

Explanation:

The angle adjacent and supplementary to the 107 degree angle is 73 degrees because 107+73 = 180.

Or you could say 180 - 107 = 73.

The base angles of the upper isosceles triangle are 73 degrees each, which means the third remaining angle (let's call it y for now) is

73+73+y = 180

146+y = 180

y = 180-146

y = 34

Refer to the diagram below. Notice how the 34 degree angle shows up twice because we have vertical angles. Consequently, the base angles of the bottom isosceles triangle are y = 34 degrees each

We can now solve for x

y+y+x = 180

34+34+x = 180

68+x = 180

x = 180-68

x = 112, so the answer is choice D

Answer:

A las 3 AM la temperatura era de -7 grados.

Step-by-step explanation:

Dado que la temperatura exterior era de 8 grados a la medianoche, y la temperatura bajó 5 grados durante cada una de las siguientes 3 horas, para determinar cuál era la temperatura a las 3 a.m. se debe realizar el siguiente cálculo:

8 - (3 x 5) = X

8 - 15 = X

-7 = X

Por lo tanto, a las 3 AM la temperatura era de -7 grados.

Answer: the required answer is 1320

Step-by-step explanation:

Total people = 12

Different phone lines = 3

We will choose the person to answer the first phone in 12 ways.

Then choose the second person in 11 ways. (11 people left)

Then choose the third person in 10 ways.  ( 10 people left)

The number of groups of 3 people can answer these lines[tex]12 \times11\times10=1320[/tex]

Hence, the required answer is 1320

Answer:

Step-by-step explanation:

With 35 internal nodes, there are 5*35=175 vertices out of which are 175-35=140 leaves.

The number of vertices in a full 5-ary tree is 175.

The number of leaves is 140.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of full trees = 5

Number of internal vertices = 35

Now,

The number of vertices.

= 5 x 35

= 175

Now,

The number of leaves.

= 175 - 35

= 140

Thus,

Number of vertices is 175.

Number of leaves is 140.

Answer:

4. m<7 = m<3 + m<2

Step-by-step explanation:

Recall: the exterior angle theorem of a triangle states that an exterior angle is equal to the sum of the two opposite interior angles of a triangle.

❌Option 1 CANNOT be true

Rationale:

m<1 is an exterior angle of triangle ∆ABC and ∆EBC, so based on the exterior angle theorem of a triangle, m<1 = m<3 + m<4 or m<1 = m<ABC + m<5

❌Option 2 CANNOT be true.

Rationale:

m<5 ≠ m<3 - m<2

❌Option 3 CANNOT be true.

Rationale:

m<6 ≠ m<3 - m<2

✅Option 4 is CORRECT.

Rationale:

Based on the external angle theorem of a triangle,

Yes, they are quite similar. the p-value obtained using the theory-based method (p < 0.0001) agree with that obtained using the randomization/simulation - based method (p < 0.0001)

P- value is the probability of obtaining a value of test statistic more extreme in the direction of alternative hypothesis than the observed one. In easy words if p -value < level of significance we reject H0 in favor of H1.

Here:

p-value < 0.0001 => we reject H0.

If the statistical software renders a p value of 0.000 it means that the value is very low, with many "0" before any other digit.

So the interpretation would be that the results are significant, same as in the case of other values below the selected threshold for significance.

Therefore, yes they are quite similar.

(b) The sample space is { boy, boy, girl}

So, the probability is 1/3.  

Answer:

The expected aptitude test score for a person whose age is 15 years is 94.

Step-by-step explanation:

Aptitude formula in function of age:

The aptitude A in function of age a is given by:

[tex]A(a) = 111.3 - 1.13a[/tex]

Find the expected aptitude test score for a person whose age is 15 years.

This is A when a = 15. Thus, finding the numeric value of the function:

[tex]A(a) = 111.3 - 1.13a[/tex]

[tex]A(15) = 111.3 - 1.13(15) = 94.35[/tex]

Rounding to the nearest whole number, 94.

In this question, we first explain the expected aptitude test after that we calculate its value.

Given:

[tex]\to \bold{Aptitude = 111.3 - 1.13*Age}[/tex]

[tex]\to \bold{Age= 15 \ years}\\\\[/tex]

Putting the age value into the Aptitude equation to calculate its value:

[tex]\bold{= 111.3 - 1.13*(15)}\\\\\bold{= 111.3 - 16.95}\\\\\bold{=94.35 \approx 94} \\\\[/tex]

Therefore, For a person 15 years of age 94, the anticipated test score for aptitude.

Standard deviation = 12.7363 kg.

To find the the variance of their weights?

Mathematically, standard deviation is equal to the square root of variance.

[tex]Sd = \sqrt{V}[/tex]

Where;

Sd is the standard deviation of the sample.

V is the variance of the sample.

Substituting into the formula, we have;

[tex]12.7363 = \sqrt{V}[/tex]

Taking the square of both sides, we have;

[tex]12.7363^{2} = V [/tex]

0.6 probability that [tex]-2 \leq x \leq 2[/tex]

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x is between -2 and 2.

Between -2 and 2, inclusive, we have -2, 0 and 2. So

[tex]P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2)[/tex]

From the table:

[tex]P(X = -2) = 0.33, P(X = 0) = 0.16, P(X = 2) = 0.11[/tex]. So

[tex]P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2) = 0.33 + 0.16 + 0.11 = 0.60[/tex]

0.6 probability that [tex]-2 \leq x \leq 2[/tex]

Answer: The distance left after 20 days is 1350 miles

Step-by-step explanation:

To calculate the distance, we use the formula:

[tex]s=\frac{d}{t}[/tex]

where,

s = speed of the bicycle = 90 miles/day

t = time taken = 20 days

d = distance travelled = ? miles

Putting values in above equation, we get:

[tex]d=(90miles/day\times 20days)=1800 miles[/tex]

Total distance to the destination = 3150 miles

Distance travalled in 20 days = 1800 miles

Distance left after 20 days = [3150 - 1800] = 1350 miles

Hence, the distance left after 20 days is 1350 miles
