Answer:

That’s easy it is 282

Step-by-step explanation:

He will now have 282 bucks altogether.

Step-by-step explanation:

We already know that he has 237 bucks before his birthday, but now he has an additional 45 bucks that he got from his birthday. With this, you can create an equation that looks like this: 237+45. You then solve the equation by adding 45 to 237, which gets you 282 bucks altogether.

Answer:

-3/2

Step-by-step explanation:

Answer:

The slope of the line shown is -3/2.

Step-by-step explanation:

You can find this by using the rise/run method between the two points.

Between the two points, the line falls 3 units down (this is the rise part) and goes 2 units to the right (this is the run part). Since the line falls 3 units down between the two points, this number would be -3, and since it runs to the right by two units, the slope can be identified as -3/2.

Answer:

35/16

Explanation:

(5*7)/2^4

= 35/2^4

= 35/16

Note:

Please mark as brainliest! <3

Answer: 54 feet.

Step-by-step explanation:

Ratio between a tree's height and its shadow's length = x : 72ft

Ratio between man's height and his shadow's length = 6ft : 8ft = 3 : 4

In order to solve this problem, we have to cross multiply the two ratios (image)

So, 4x = 216.

By solving this equation we learn that x = 54ft

So, the tree is 54 feet tall.

I am not a professional, simply using prior knowledge.

Note- It would mean the world to me if you could mark me brainliest!

Answer:

x+49+90=180sum of interior angle of triangle

x=180-139=41 is your answer

Answer:

x = 7

If a is parallel to b, then 9(7) + 11 = 74.

Step-by-step explanation:

We don't know if the lines are parallel, so we need to see what x is in 9x + 11 = 74, then substitute that value for x in the equation. If both sides are true, the two lines are parallel.

9x + 11 = 74

Step 1: Subtract 11 from both sides.

9x = 63

Step 2: Divide both sides by 9.

x = 7

To make sure, let's substitute 7 for x in the earlier equation.

9(7) + 11 = 74

Step 3: Multiply 9 by 7 to get 63.

63 + 11 = 74

Step 4: Add 11 to 63 to get 74.

74 = 74

The two sides are equal, so a and b are parallel. The definition of a converse is the reverse of a conditional statement. As a result, the converse here is "If a is parallel to b, then 9(7) + 11 = 74."

Answer:

It doesn't make sense

Step-by-step explanation:

Given

Statement: .... at a speed of 35 miles .....

Required

Does it make sense?

In motion, speed is measured in km/h, m/s, miles per hour (depending on context) while distance is measured in km, m or miles.

However, the given statement mention the unit of speed to be miles which is incorrect.

Hence, we can conclude that the statement does not make sense.

A correct statement would be: I drove at a speed of 35 miles per hour .......

Answer:

Step-by-step explanation:

This graph is a monster. No one should solve it by hand. Desmos drew the one below. The way the graph looks, I would say it is negative at (4,0)

The first choice isn't a point on the graph.

(0,0) goes both ways.

(-2,4) is positive.

Answer:

1001/1500

Step-by-step explanation:

The easiest method for doing this is to just average the two numbers.

e.g. to find a number x between the two numbers ab and cd

x=12[ab+cd]

=12[adbd+bcbd]

=ad+bc2bd

In this case…

x=(2×5)+(3×4)2×2×5=10+1230=2230=1115

You can easily see where that came from.

23=1015 and 45=1215

and the ‘common denominator’ means you just have to pick a value between 10 and 12 . i.e. 11

But you can also say…

23=100150 and 45=120150

and choose any of 101150,102150,...,119150

or

23=10001500 and 45=12001500

and choose any of 10011500,10021500,...,11991500

Answer:4/5 and 2/3 each have a common bottom of 15 so 4/5 is

12/15 and 2/3 will be 10/15

Step-by-step explanation:So than 12/15 forget the bottom don't subtract the bottom just look at it like [12-10] then you got 2 then you go back to the bottom and put it together so your answer is [2/15]

Answer:

0.0037 = 0.37% probability that the home team would win 65% or more of its games in a simple random sample of 80 games

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

The home team therefore wins 50% of its games

This means that [tex]p = 0.5[/tex]

Determine the probability that the home team would win 65% or more of its games in a simple random sample of 80 games

Sample of 80 means that [tex]n = 80[/tex] and, by the Central Limit Theorem:

[tex]\mu = p = 0.65[/tex]

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.5*0.5}{80}} = 0.0559[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 0.65. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.65 - 0.5}{0.0559}[/tex]

[tex]Z = 2.68[/tex]

[tex]Z = 2.68[/tex] has a pvalue of 0.9963

1 - 0.9963 = 0.0037

0.0037 = 0.37% probability that the home team would win 65% or more of its games in a simple random sample of 80 games
