Answer:

∠A = 126°

Step-by-step explanation:

Supplementary angles are angles that add up to equal 180°

Given that ∠B = 54°, we can subtract 54° from 180°.

180° - 54° = 126°

∠A = 126°

Answer:

B. About 2% of the boys are eligible to be a small forward on the team

Step-by-step explanation:

Recall : 1 feets = 12 inches

Point guard = 6’2" – 6’6" tall = 74 - 78 inches

Mean = 70 ; Standard deviation = 4

Z = (x - mean) / standard

P(x < 74) = (74 - 70) / 4 = 1

P(x < 78) = (78 - 70) / 4 = 2

0.97725 - 0.84134 = 0.13591

Small forward : 6'6" = 78 inches

P(x ≥ 78) = (78 - 70) / 4 = 2

P(z ≥ 2) = 0.02275 = 2.275% about 2%

Centre : 6'8" = 80

P(x ≥ 80) = (80 - 70) / 4 = 2.5

P(z ≥ 2.5) = 0.0062097 = 0.62%

About 2% of the boys are eligible to be a small forward on the team. Then the correct option is B.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

A high school basketball coach is selecting his team.

The minimum and maximum height requirements are as follows:

Point Guard: Small Forward: Center:

6’2" – 6’6" tall at least 6’6" tall at least 6’8" tall

The heights of the Lincoln High School boys have a normal distribution with a mean height of 70 inches and a standard deviation of 4 inches.

The value of the z-score will be

[tex]z = \dfrac{x - \mu }{\sigma}[/tex]

[tex]P(x < 74) = \dfrac{74-70}{4} = 1 \\\\P(x < 78) = \dfrac{78-70}{4} = 2[/tex]

0.97725 - 0.84134 = 0.13591

Small forward: 6'6" = 78 inches

[tex]P(x \geq 78) = \dfrac{78- 70 }{4} 2\\\\\\P(z \geq 2) = 0.02275 = 2.275 \%[/tex]

Centre: 6'8" = 80 inches

[tex]P(x \geq 80) = \dfrac{80- 70 }{4} 2\\\\\\P(z \geq 2.5) = 0.0062097= 0.62 \%[/tex]

Answer:

-3 ≤ x <-2

Step-by-step explanation:

First, you should set up the equation to solve it, which is,

21 ≤ -3(x-4)<18

Then you should simplify the equation to,

21 ≤ -3x+12<18

Then subtract 12 from both sides.

9 ≤ -3x<6

Lastly, divide -3 from both sides.

-3 ≤ x<-2

Answer:

Its removable

Step-by-step explanation:

yes

this is a removable discontinuity

Here we have the piecewise function:

[tex]f(x) = \frac{-4x}{x - 3}[/tex]     if x < 5

[tex]f(x) = -7x + 25[/tex]    if x > 5.

We want to see which type of discontinuity we have at x = 5.

Remember that:

If we have two asymptotes, then is an infinite discontinuity

if just one point is missing, then it is a removable discontinuity

If the value drastically changes after the discontinuity, then its a jump discontinuity

Mixed case is when two of these happen.

Because we have a piecewise function, we need to evaluate both parts in x = 5.

If both parts give the same value, then we will have a removable discontinuity

if the values are different, then we have a jump discontinuity.

first part:

f(5) = -4×5/(5 - 3) = -20/2 = -10

second part:

f(5) = -7×5  + 25 = -35 + 25 = -10

So we got the same value, which means that this is a removable discontinuity

in the image below you can see the graph of the piecewise function, and see that as x tends to 5, both sides of the function tend to the same value.

Step-by-step explanation:

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

Explanation:

It's not stated, but I'm assuming your teacher meant to say AB = BC since triangle ABC is isosceles.

From that, we can prove that triangle ADB is congruent to triangle CDB by using the HL rule. Then that means AD = DC = 3 and AC = AD+DC = 3+3 = 6.

Now focus on triangle ADB. It's a right triangle which allows us to use one of the sine, cosine or tangent ratios. We'll use cosine to connect the adjacent side AD = 3 with the unknown hypotenuse AB. The reference angle is BAC = 55. We can shorten this to angle A = 55 if we focus on triangle ADB.

So,

cos(angle) = adjacent/hypotenuse

cos(A) = AD/AB

cos(55) = 3/AB

AB*cos(55) = 3

AB = 3/cos(55)

AB = 5.2303 approximately, make sure your calc is in degree mode

Therefore, the perimeter is

p = AB+BC+AC

p = 5.2303 + 5.2303 + 6

p = 16.4606

p = 16.46

Answer:

p = 16.4

Step-by-step explanation:

cos 55 = 3/x

x = 5.2

BA = 5.2

line AD is = to line DC because it is an isoscles triangle

BC is congruent to BA so BC is also 5.2

add all sides to find perimeter

5.2 + 5.2 + 6 = 16.4

[tex]x_{v}[/tex]Answer:

The vertex of an up - down facing parabola of the formy = ax" + bx + c is xy =

The parabola params are:

a = 8, b = -14, c =3

[tex]x_{v}=b/2a[/tex]

[tex]x_{v}[/tex]=-(-14)/2·8

simplify

[tex]x_{v}[/tex]=-(-14)/2·8

[tex]x_{v} = 7/8[/tex]

Plug in [tex]x_{v}[/tex]=7/8to find the [tex]y_{v}[/tex] value

[tex]y_{v}[/tex]= -25/8

Therefore the parabola vertex is

(7/8 , -25/8)

If a < 0, then the vertex is a maximum value

If a > 0, then the vertex is a minimum value

a = 8

Minimum(7/8 , -25/8)

Answer:

x = 12

Step-by-step explanation:

This is a supplementary angle so the right side is equal to 90°. This means the other side must also equal 90°

So subtract 20° from 90° and you get 70°

Next you can just (6(12)-2) or continuously substitute until you get the right answer.
