will give more p0ints if correct

Answer:

14

Step-by-step explanation:

so first our equation is: -4a+2b so a is -2 right? okay so your going to do

-4 x -2 which you get 8 (minus times minus is postive). and now for 2b: 2x3 is 6 so 6+8 is 14

Dado :

Diámetro del círculo = 47 mm

Radio del círculo = diámetro / 2

Por lo tanto, Radio = 47 mm / 2

Radio = 23,5 mm

Answer:

Option C, 13.7 cm

Step-by-step explanation:

Cos(31°) = [tex]\frac{x}{15}[/tex]

=> Multiply 15 on both sides of "="

Cos(31°) * 15 = x

13.7 = x

Answer:

A: y = 9.5x + 22.5

Step-by-step explanation:

Answer:

y=2x+2

Step-by-step explanation:

Just look at the bottom dot which is 0,2 and y=2x+2 is the only one that works:

2=(2×0)+2

2=2

but the other is:

2=(3×0)

2=3

which isn't true,

therefore it must be the first one.

The answer is "0.096".

Step-by-step explanation:

In this question, the X is a number of the students who enroll in a psycholog y course,  follows a Poisson distribution with mean [tex]= \lambda= 105[/tex]  

[tex]\therefore P(X=x)=\frac{e^{-105} 105^{x}}{x!},(x=0,1,2,3.....)\\\\\to p(teach\ two \ sections) = P(X \geq 119)\\\\=1-P(X<119)\\\\=1-\sum_{x=0}^{118}P(X=x)\\\\=1-\sum_{x=0}^{118}\frac{e^{-105} 105^{x}}{x!}\\\\=0.0956747863537\\\\=0.096\\[/tex]

Answer:

50

Step-by-step explanation:

2000/40=50

Answer:

The train travels 50 miles per hour

Step-by-step explanation:

You can solve this by dividing 2,000 by 40.

Answer:

No, You divide 3.56/4 and you get 0.89 and then after that you multiply it by 7 so you do0.89x7=6.23

Answer: Choice A

angle GAF = angle TAE is the lie (aka false statement)

========================================================

Explanation:

Let's go through each answer choice to see which is true or which is false.

-----------------------------

Choice A

The markers for angles GAF and TAE are different. Both would need to have a single angle marker, or a double angle marker. The differing markers indicates the angles aren't the same.

Also, note that angle TAG isn't a 180 degree angle, or that point G isn't on line TA. We need this to be the the case, so that two vertical angles form. However, such a thing doesn't happen.

So that's why angles TAE and GAF aren't the same measure.

Choice A is the answer. You can stop here if you wanted.

-------------------------------

Choice B

Let

x = measure of angle TAE

y = measure of angle TAH

z = measure of angle HAF

We can see that x+y+z = 180, since angle EAF is a straight angle. The diagram gives y = 90 and z = 50, so,

x+y+z = 180

x+90+50 = 180

x+140 = 180

x = 180-140

x = 40

Angle TAE is 40 degrees. It adds with angle FAH to get 40+50 = 90, showing that the two angles are indeed complementary.

Choice B is a true statement, so we can rule it out.

-------------------------------

Choice C

Angle TAF is composed of angles TAH and HAF

Adding the two angles gets us 90+50 = 140, which is larger than 90.

Therefore angle TAF is obtuse.

Choice C is a true statement, and it can be ruled out as well.

Technically you could have stopped at choice A once you found the lie, but I figured to show why choices B and C could be ruled out.

Answer:

0

Step-by-step explanation:

-2 * -2 = 4

4  * 2 = 8

4 * -2 = -8 + 16 = 8

8-8 = 0

Answer:

5 Hours

Step-by-step explanation:

2 : 30 = 1 : 15

75 ÷ 15 = 5

Answer:

5 hours

Step-by-step explanation:

30/2 = 15 miles per hour

75/15 = 5 hours

Answer: 36

Step-by-step explanation:

This is a geometric progression. The formula for a geometric progression is given as:

= ar^n-1

where

a = first term = 16

r = common ratio = 24/16 = 1.5

n = 3

Therefore, the 3rd term will be:

= ar^n-1

= 16 × 1.5^3-1

= 16 × 1.5²

= 36

Therefore, the third term of the progression is 36.

Answer:

$5,376

$47,376

Step-by-step explanation:

Given :

Price of current model = $42,000

Percentage increase in price = 12.8%

Price increase in dollars :

12.8% of $42000

0.128 * $42000

= $5,376

Price of the next model :

Price of current model + increase in price

$42000 + $5376

= $47,376
