Answer:

11.4 units

Step-by-step explanation:

b/sinB = a/sinA

b/sin(42) = 17/sin(88)

b = sin(42) × 17/sin(88)

b = 11.38215401

Answer:

Step-by-step explanation:

Use the law of sines.

$\frac{sin A}{a} = \frac{sin B}{b} \\$

Plug values in.

$\frac{sin88}{17} = \frac{sin42}{b}\\$

Cross multiply.

$bsin88 = 17sin42\\b = 11.38$

Hope that helps.

Answer:

Option B and C is correct

Step-by-step explanation:

<h3><u>Given</u>;</h3>

Priya has 5 pencils, each x inches in length.
Total length = 34.5 inches.

Now,

5 times x = 34.5

So,

5x = 34.5

34.5 ÷ 5 = x

Thus, 5x = 34.5 and 34.5 ÷ 5 = x are the answer

In a number with at least two digits, the last number was removed. The resulting number was n smaller than ghe previous one.

BartSMP [9]

Answer:

The largest possible value of n is 11.

(A) is correct option.

Step-by-step explanation:

Given that,

The number with at least two digits,the last number was removed. The resulting number was n smaller than the previous one.

We need to find the largest possible value of n

Using given data,

The smallest number of two digit is 10.

Now, we removed last digit then we get 1 which is equal to 10 divided 10.

So, n = 10

But the largest number of two digit is 99.

We removed last digit then we get 9 which is equal to 99 divided 11.

So, n = 11

Hence, The largest possible value of n is 11.

(A) is correct option.

In a particular region, for families with a combined income of $75,000 or more, 15% of these families have no children, 35% of t

SCORPION-xisa [38]

Answer:

The probability distribution for x:"number of children per family for this income group" is:

$\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\$

Step-by-step explanation:

With the information given we have the relative frequencies of each category.

We know:

$\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\$
