10 because she already knows 3 so then you divide 80 (number of words she hasn’t learned) by 8 (the number of weeks) and you get 10.

A restaurant interest survey of 230 citizens in a town showed that 80 want a new Chili's, 120 want a new Red Lobster, and 20 wan

The right solution to the given question is " $\frac{2}{23}$ ", " $\frac{6}{23}$ " and " $\frac{5}{23}$ ".

According to the question,

$a+b+c+d = 230$
$b = 20$
$a+b = 80$

By putting the value of "b", we get

$a+20=80$

$a = 80-20$

$a = 60$

$b + c=120$

By putting the value of "b", we get

$20+c=120$

$c = 120-20$

$c = 100$

$d = 230-60-100-20$

By putting the values of "a", "b", "c" and "d", we get

$d = 50$

(a)

P(both Chili's and Red lobster),

= $\frac{b}{a+b+c+d}$

= $\frac{2}{23}$

(b)

P(only chili's),

= $\frac{a}{a+b+c+d}$

= $\frac{6}{23}$

(c)

P(neither),

= $\frac{d}{a+b+c+d}$

= $\frac{5}{23}$

Find the value of x. Round the nearest tenth

zimovet [89]

Answer:

x ≈ 30.7

Step-by-step explanation:

Reference angle = 61°

Opposite side length = x

Adjacent side length = 17

Applying the trigonometric function TOA, we have:

Tan 61 = opp/adj

Tan 61 = x/17

17 × Tan 61 = x

x ≈ 30.7
