Use PEMDAS

PEMDAS stands for: Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.

So.. in 7+5x6, you first multiply (Tip: If you don't see parenthesis or exponents, jump to multiplication) 5 and 6. (30) NOw, you add 5x6 (30) with 7 (=37)

Can someone please help me out with this as ive tried to put everything to solve it but im still wrong.
tangare [24]
In an equilateral triangle all the sides are equal. This means that all the angles add up to 180 degrees.
Divide 180 by 3 and you get 60.
You want an exterior angle so you cut the angle in half ( it is now 30 )
Because the base and the line are parallel (form right angle if drew line connecting them) x is equal to
90-30=60

Complete the TABLE of values for x+y=6.
kvasek [131]

Answer:

X        Y

-2       8

-1        7

0        6

1         5

2        4

3        3

Step-by-step explanation:

We have the equation: x+y=6

We want to get this in the form: y=mx+b (or in this case y=x+b)

To do this we need y to be positive and by itself

So we subtract y from both sides and divide by -1 (we divide by -1 because otherwise y would be negative and that does not fit our template of y=x+b)

Doing this we have

-x+6=y

From here we just plug in numbers -2 to 3 which I will assume you know how to do

X        Y

-2       8

-1        7

0        6

1         5

2        4

3        3

This helicopter has a rotor that moves at a rate of 600 spins per minute while flying. Which statement is supported by this info
jeka57 [31]

Answer: d. The helicopter rotor will spin 36,000 times in 1 hour

Step-by-step explanation:

Option A is wrong because in 40 minutes the rotor will spin:

= 40 * 600

= 24,000 times

Option B is wrong because we cannot know the number of times the rotor will spin before being lifted off of the ground with the details given.

Option C is wrong because in 3 hours the rotor will spin:

= 600 * 3 * 60 minutes

= 108,000 times

Option D is correct because in 1 hour the rotor will spin:

= 600 * 1 * 60 mins

= 36,000 times

The critical value t* gets larger as the confidence level increases. True or false?
posledela

Answer:

We can find the critical value t_{\alpha/2}

And for this case if the confidence increase the critical value increase so then this statement is True

Step-by-step explanation:

For a confidence level given c, we can find the significance level like this:

\alpha=1 -c

And with the degrees of freedom given by:

df=n-1

We can find the critical value t_{\alpha/2}

And for this case if the confidence increase the critical value increase so then this statement is True
