Answer:

12.5%

Step-by-step explanation:

There are 4 walls to choose from, and 2 scenes to choose from. So the number of combinations is 2×4=8. One of those is the ocean scene on the gym wall. So the probability is:

P = 1/8

P = 12.5%

The sum of three consecutive numbers is 276. What is the smallest of these intengers?
shtirl [24]

Answer:

91

Step-by-step explanation:

Let x be the smallest one:

● x is the first number

● x+1 is the second number

● x+2 is the third number

The sum of these numbers is 276

● x+(x+1)+(x+2) =276

● x+x+1+x+2 = 276

● 3x + 3 = 276

Substract 3 from both sides:

● 3x+3-3 = 276-3

● 3x = 273

Divide both sides by 3

● (3x)/3 = 273/3

● x = 91

So the smallest one is 91

A standardized test was given to a set of high school juniors and the distribution of the data is bell shaped. The mean score is
stira [4]

Answer:

920 points.      

Step-by-step explanation:    

We have been given that the mean score for a standardized test is 800 and the standard deviation is 120. To qualify for a special summer camp for accelerated students, a student must score within the top 16% of all scores on the test.

First of all we will find probability of 0.16 using normal distribution table.

Using normal distribution our Z score will be 0.994458

Now we will use raw-score formula to find the score (x) that a student must make to qualify for summer camp.  

x=\text{Mean}+\text{ Standard deviation* Z score}

Upon substituting our given values in above formula we will get,

x=800+120\times 0.994458

x=800+119.33496

x=919.33496

Upon rounding to nearest whole number we will get,

x=920

Therefore, a student must make 920 points to qualify for summer camp.
