Step-by-step explanation:

Answer:

The value of x is 67.5

Step-by-step explanation:

The sum of the measures of the angles around a point is 360°

Let us solve the question

∵ In the given figure there are 3 adjacent angles around one vertex

→ By using the rule above

∴ The sum of their measures is 360°

∵ One of the angles is a right angle

∵ The measure of the right angle is 90°

∵ The measures of them are x, 3x, and 90°

∴ x + 3x + 90° = 360°

→ Solve the equation by adding the like terms to find x

∵ (x + 3x) + 90 = 360

∴ 4x + 90 = 360

→ Subtract 90 from both sides

∵ 4x + 90 - 90 = 360 - 90

∴ 4x = 270

→ Divide both sides by 4

∴ x = 67.5

∴ The value of x is 67.5

Heres a screenshot if you ask why?

Answer:

h α t

h = kt

k = h/t

350 = k5

350/5 = k

k = 70

Step-by-step explanation:

Given that :

Ballon height varies directly as the Ascent time in minutes

Height of hot air Ballon rises 350 feets in 5 seconds

Expressing as a direct variation :

Let height of Ballon = h

Time it takes to rise = t

h α t

h = kt

k = h/t

350 = k5

350/5 = k

k = 70

Answer:

The coordinates of the vertices of A'B'C' is:

Step-by-step explanation:

Given the coordinates of the triangle

Reflection in the line y=x

We know that the rule of reflection in the line is y = x is:

(x, y) → (y, x)

Thus,

The coordinates of the vertices of A'B'C' for the reflection in the y = x

(x, y)         →        (y, x)

A(7, -4)     →        A'(-4, 7)

B(6, 4)      →        B'(4, 6)

C(-1, -5)     →       C'(-5, -1)

Thus, the coordinates of the vertices of A'B'C' is:

Answer:

x = 15

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )

x² = 9 × 25 = 225 ( take the square root of both sides )

x = [tex]\sqrt{225}[/tex] = 15

Answer:

3.25

Step-by-step explanation:

Answer:

Step-by-step explanation:

a.)

<A = 90 - 67 = 23*      A = (a^2 + 14.72^2 = 16^2) = a = 6.25

<B = 67*                      B = (sin67 = b/16) = sin67*16 = 14.73

<C = 90*                      C = 16

b.)

a = (a^2 + 2^2 = 6^2) = a = 5. 66         <A = (cosA = 2/6) = 70.53*

b = 2                                                      <B = 90-70.53 = 19.47*

c = 6                                                      <C = 90*

Step-by-step explanation:

-17 - (-7) = -24

a = -24

Answer:

b) a = -10

Step-by-step explanation:

a + (-7) = -17

simplify

a - 7 = -17

add 7 to both sides of the equation

a - 7 + 7 = -17 + 7

a = -17 + 7

a = -10

Answer:

There are 182.88  cm in 2 yards.

Step-by-step explanation:

Given that,

1 inch = 2.54 cm

We need to find how many centimeters are there in 2 yards.

We know that,

1 yard = 36 inch

⇒ 2 yards = (2×36) inches

= 72 inches

It means,

72 inches = (72 × 2.54) cm

= 182.88  cm

Hence, there are 182.88  cm in 2 yards.

Complete question is;

After examining daily receipts over the past year, it was found that the green parrot italian restaurant has been grossing over $2200 a day for about 85% of it's business days. Using this as a reasonably accurate measure, find the probability that the green parrot will gross over $2200:

A. At least 5 of the next 7 business days.

B. at least 5 of the next 10 business days.

C. less than 3 of the next 5 business days.

d. Exactly 7 of the next 10 business days

e. At least 1 of the next 5 business days.

Answer:

A) P(X ≥ 5) = 0.9262

B) P(X ≥ 5) = 0.9986

C) P(X ≤ 2) = 0.0266

D) P(X = 7) = 0.1298

E) P(X ≥ 1) = 0.9999

Step-by-step explanation:

This is a binomial probability distribution problem and as such we will use the formula;

P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)

A. At least 5 of the next 7 business days will be;

P (X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7)

P(X = 5) = C(7, 5) × 0.85^(5) × (1 - 0.85)^(7 - 5)

P(X = 5) = 0.20965

P(X = 6) = C(7, 6) × 0.85^(6) × (1 - 0.85)^(7 - 6)

P(X = 6) = 0.396

P(X = 7) = C(7, 7) × 0.85^(7) × (1 - 0.85)^(7 - 7)

P(X = 7) = 0.320577

Thus;

P(X ≥ 5) = 0.20965 + 0.396 + 0.320577

P(X ≥ 5) = 0.9262

B. Probability of at least 5 of the next 10 business days will be;

P(X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)

From online binomial calculator attached, we can see that the answer is;

P(X ≥ 5) = 0.9986

C. Probability of less than 3 of the next 5 business days will be;

P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)

From online binomial calculator attached, we can see that the answer is;

P(X ≤ 2) = 0.0266

D. Probability of exactly 7 of the next 10 business days will be;

P(X = 7) = C(10, 7) × 0.85^(7) × (1 - 0.85)^(10 - 7)

P(X = 7) = 0.1298

e. Probability of at least 1 of the next 5 business days will be;

P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

From third image attached using online binomial calculator, we have;

P(X ≥ 1) = 0.9999
