On which number line do the points represent negative seven and one over two and +1?

7 0

A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.

Literal Equations? Anyone? The problems are in the picture! Show solution please! Thanks in advance!

lapo4ka [179]

The way to solve is using order of operation PEMDAS. Its very easy. You should be able to solve it yourself. I'll give you the first 3 answers:
1. g/6=x
2. x=1/2u+1
3. z-m=x
I would give you all the answers but it would be best if you did it yourself. You teacher and parents would be much happier if you learnt the skill. Hope this answer helps! Mark as brainliest! :)

Over the course of a week, an environmental activist randomly stopped 1,200 people on the street and asked whether they were wil

sdas [7]

Sample Size = n = 1200
Number of people who are willing to pay higher = x = 708

Proportion of people who are willing to pay higher = p = $\frac{708}{1200}= \frac{59}{100}=0.59$

Confidence Level = 99%
Z Value = z = 2.58

The confidence interval about a population proportion can be calculated as:

$(p-z \sqrt{ \frac{p(1-p)}{n} }, p+z \sqrt{ \frac{p(1-p)}{n} })$

Using the values, we get:

$(0.59-2.58 \sqrt{ \frac{0.59(0.41)}{1200} } ,0.59+2.58 \sqrt{ \frac{0.59(0.41)}{1200} }) \\ \\ 
(0.553,0.627)$

Thus, at 99% confidence level, the estimated proportion of people willing to pay higher prices for gas in order to protect the environment lies between 0.553 and 0.627.

A Scout on top of a 1500-ft. mountain spots a campsite.

nlexa [21]

Answer: The distance from the campsite to the foot of the mountain is 2310 ft (approx)

Step-by-step explanation: We have been given that the scout on the mountain top has spotted a campsite and he did so while looking down from a 33° angle of depression. If we label his position as point A, the foot of the mountain as point B and the campsite as point C, then it means the scout has formed an angle of 57° between point A and point B. Now we have a right angled triangle ABC with angle A measuring 57°

Using the trigonometrical ratio of tangent

Tan A = opposite/adjacent

Tan 57 = BC/1500

1.5399 = BC/1500

When you cross multiply both sides you have

1.5399 × 1500 = BC

2309.85 = BC

Approximated to the nearest foot,

BC = 2,310 ft
