What is 0+50×1-60×0+10=

Answers

Answer 1
Answer: Hi, Susieq2!
You use something called "PEMDAS" to solve problems like these!
PEMDAS= Parenthesis, Exponents, Multiplication,Division,Addition, Subtraction.
There are no parenthesis or exponents!
Multiplication!
0+(50*1)-60-(60*0)+10 

0+50-60-0+10 
50-60+10 

I hope this helps;)

Answer 2
Answer: Hey there

To solve this problem we have to use - PEMDAS. 

= Parenthesis, Exponents, Multiplication,Division,Addition, Subtraction 

0+50×1-60×0+10= In this problem the first thing we have to solve is multiplication.  

⇒ 0 + 50 × 1 -60 × 0 +10 

= 0 + 50 -60 + 0 + 10

Next we have to solve addition 

50-60+10 

Next step is to solve subtraction 

-10+10 = 0 

0 + 50 × 1 -60 × 0 +10= 0 

answer = 0

Becky lives 5 5/8 miles from school. Steve lives 1 5/9 times as far from the school as Becky. How far does Steve live from the school?

Answers

Steve lives 1 5/9 as far as Becky so how far he lives should be 1 5/9(5 5/8) which is equal to 8.75 or 8 3/4 (I used a calculator but if you were to do this by hand it would be much easier to turn your mixed numbers into improper fractions)

Determine if the system has one solution, infinitely many solutions, or no solution. x=-7y+34 x+7y=32

Answers

Answer:

NO Solution

Step-by-step explanation:

First, from the first equation let's move the Y term to the other side to match with the second equation.

x=-7y+34\n\nx(+7y)=-7y+34 (+7y)\n\nx+7y=34

Now lets compare the two equations.

x+7y=34\nx+7y=32

Since the left sides are the same but the right sides of the equations aren't, we can see there are no solutions to this system.

Ginny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. When she began her study, the frog population was estimated at 1,200. Which function represents the frog population after x years?

Answers

Answer:

y = 1200(0.97)^x

Step-by-step explanation:

Ginny determines that the population is decreasing at an average rate of 3% per year.

So, this is an exponential decay case

Formula : y = a(1-r)^n

where a is the amount after n years

a is the initial amount

r is the rate of depreciate

n is the number of years

Now we are given that When she began her study, the frog population was estimated at 1,200.

So, a=1200

r = 3% = 0.03

n =x

Substitute the values in the formula:

y = 1200(1-0.03)^x

y = 1200(0.97)^x

Hence function represents the frog population after x years is y = 1200(0.97)^x

Hello,

x_(0)=1200

x_(1)=(97)/(100)*1200

x_(2)=((97)/(100))^2*1200

x_(3)=((97)/(100))^3*1200
...
x_(n)=((97)/(100))^(n)*1200

A proposed null hypothesis states that there is no difference in the population mean heights of two neighboring districts. The difference of the sample means is 10 cm, and the standard deviation of the difference of sample means is 6 cm. Which conclusion can we draw at the 68% confidence level?

Answers

Answer:

Explained

Step-by-step explanation:

Null hypothesis is something that states that there is no difference between the population means, while the alternative hypothesis states that there is difference between the two.

So, If the difference of the sample means is 10cm, and the standard deviation of the difference of sample means is 6 cm. Then  the population means of the two districts will be different according to the manual solution.

Answer:

The population means of the two districts are different.
