What is the value of x to the nearest tenth

Mathematics
1 answer:
marishachu [46]3 years ago
4 0

You will have to use trig to solve this:

The side you have is adjacent to the known angle

The side you are looking for is opposite the known angle

^^^This means you need to use tan:

tan(24) = \frac{x}{12}

.445222 = \frac{x}{12}

^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x

5.3 ≈ x

Hope this helped!

Suppose taxi fare from Logan Airport to downtown Boston is known to be normally distributed with a standard deviation of $2.50.
Mariulka [41]

Answer:

95% Confidence interval for taxi fare:  ($20.5,$24.2)

Step-by-step explanation:

We are given the following data set: for fares:

$22.10, $23.25, $21.35, $24.50, $21.90, $20.75, and $22.65

Formula:

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{156.5}{7} = 22.35

95% Confidence interval:

\bar{x} \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

22.35 \pm 1.96(\frac{2.5}{\sqrt{7}} ) = 22.35 \pm 1.85 = (20.5,24.2)

Answer:

x = 34/13

Step-by-step explanation:

3(5x - 6) + 2(x + 8)

15x - 18 = 2x + 16

15x = 2x + 34

13x = 34

x = 34/13

Answer:

C, x ≥ 14.96

Step-by-step explanation:

Step 1: Add 3.408 to both sides.

2.2x − 3.408 (+ 3.408) ≥ 29.504 (+ 3.408)

2.2x ≥ 32.912

Step 2: Divide both sides by 2.2.

2.2x (÷ 2.2) ≥ 32.912 (÷ 2.2)

x = 14.96
