Answer:

Veronica left a tip of  $6.87

Step-by-step explanation:

3.50×2= 7

6.95×2= 13.9

7.95+12.95+15.95+7+13.9 = 41.8

0.25×41.8= 10.45

41.8-10.45= 31.35

0.0925×31.35 = 3

31.35+3 = 34.35

0.20×34.35 = 6.87

Step-by-step explanation:

yx = 2

if x = 7

y(7) = 2

y = 2/7

yx = 2

if y = 2

2(x) = 2

x = 1

Answer:

D (No, because there are values in the interval that are greater than 0.85.)

Step-by-step explanation:

edge2021 :)

The true proportion of times this weather forecaster correctly predicts the weather is less than 85% are; No, because there are values in the interval that are greater than 0.85.

Suppose we're given that:

Favourable Cases X (in count, in sample)

Sample Size N

Level of significance =[tex]\alpha[/tex]

Then, the sample proportion of favorable cases is:

[tex]\hat{p} = \dfrac{X}{N}[/tex]

The critical value at the level of significance [tex]\alpha[/tex] is [tex]Z_{1- \alpha/2}[/tex]

The true proportion of times this weather forecaster correctly predicts the weather is less than 85% are given as;

IT is No, because there are values in the interval that are greater than 0.85.

Answer:

12^4 = 20736

Step-by-step explanation:

The property of exponents used to simplify : 12^8/12^4

The division property :

a^x / a^y = a^(x - y)

Therefore ;

12^8/12^4

12^8 / 12^4 = 12^(8 - 4) = 12^4 = 20,736

Answer:

Step-by-step explanation:

(g∘f)(4) = g(f(4))

= g(-4³)

= g(-64)

= | ⅛(-64)-1 |

= | -8-1 |

= 9

The value of (g · f)(4) is found to be 9.

A function is a kind of relation in which the domain(x) has one and only one image in the range(y).

A composite function is a kind of function that combines two functions in the order in which it is written.

(g ·f)(x) = g(f(x))

We have to f(4) and substitute that g(x).

f(x) = -x³

f(4) = -64

[tex]g(x) = \left| \frac{1}{8} x-1 \right|\\\Rightarrow g(f(x))= \left| \frac{-64}{8}-1 \right|\\=\left| -8-1 \right|\\=\left| -9\right|\\=9[/tex]

Thus, we have found the value of (g · f)(4) to be 9. The correct answer is option C.

Answer:

[tex]\frac{55}{14}[/tex]

Step-by-step explanation:

First, we convert the mixed numbers into improper fractions: [tex]1\frac{3}{7} =\frac{10}{7}[/tex], and [tex]2\frac{3}{4}=\frac{11}{4}[/tex]. Now, we multiply the fraction using the multiplication rule, [tex]\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}[/tex]: [tex]\frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}[/tex].

Thus, the product of the two given fractions is 55/14.

Answer:

The height of the tree is approximately 21.4 feet

Step-by-step explanation:

We list out the question parameters first as follows;

The distance from the base of the tree where the angle of elevation is measured, d = 10 feet

The angle of elevation to the top of the tree from 10 feet from the base, θ = 65°

Let 'h' represent the height of the tree, then we have;

The line formed by the angle 65° angle, the height of the tree, 'h', and the distance 'd', form a right triangle with 'h' being the opposite leg to the given reference angle, 65°, and 'd' being the adjacent leg

By trigonometric ratio, we have;

[tex]tan(\theta) = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = \dfrac{h}{d}[/tex]

∴ h = d × tan(θ)

Plugging in the given values, we get;

h = 10 feet × tan(65°) = 21 feet [tex]5\frac{11}{32}[/tex] inches

∴  By rounding to the nearest tenth of a foot, the height of the tree, h ≈ 21.4 feet.
