Answer 1

Answer:

34 or B

Step-by-step explanation:

180-112=68

68/2=34

Since the 2 angles equal 180, and we already know one is 112, we can subtract that. and because it is 2 times a number, we need to get half of whatever that number is, which was 68, and we got 34. this would be the value of y, because when plugged in, 112+2(34)=180.

if 300 people come to the gym on a given day, approximately how many people would you expect to exercise for more than 136 minutes?

Answers

Answer: 120

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

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

Answers

Answer:

C 13

Step-by-step explanation:

2 right-angled triangles. so, Pythagoras applies for both.

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

starting with the small triangle we have

5² = 3² + x-part²

x-part² = 5² - 3² = 25 - 9 = 16

x-part = 4 cm

the markers indicate that x-part as the third side of the small triangle is exactly as long as the other part of x.

that means

x = 2 × x-part = 2 × 4 = 8 cm

for the large triangle we then get

y² = x² + 15² = 8² + 225 = 64 + 225 = 289

y = 17 cm

and so,

y - x = 17 - 8 = 9

but that is not an answer option.

and now it dawned on me : x was not meant to be the whole third side of the large triangle. x is supposed to be only the upper part of that side, above the small triangle.

in essence, x is what I originally called "x-part".

so, the Pythagoras calculations remain basically the same, but we should name things differently like

5² = 3² + small-side²

small-side = 4 cm

x = small-side = 4 cm

long-side = 2 × small-side = 2 × 4 = 8 cm

y² = long-side² + 15² = 8² + 15² = 64 + 225 = 289

y = 17 cm

and the actual y - x = 17 - 4 = 13 cm

What is the decimal equivalent to -3 3/12

What is the decimal equivalent to -3 3/12

[tex]\huge\rm{ANSWER:}[/tex]

[tex]\huge \rm{ - 3.25}[/tex]

[tex]\huge\rm{SOLUTION:}[/tex]

To begin, keep in mind that - 3 3/12 is a mixed number, also known as a mixed fraction. It has a valid fraction as well as a complete number.

The following is a list of the numbers in a mixed fraction:

[tex]\huge \rm{ - 3}[/tex] the whole number.

[tex]\huge \rm{ 3}[/tex] the numerator

[tex]\huge \rm{ 12}[/tex] the denominator

Follow these procedures to convert -3 3/12 from a mixed number to a decimal number:

Divide the denominator by the numerator to convert the correct fraction to decimal.

3 ÷ 12 = 0.25

To get the entire number of the mixed fraction, multiply it by this decimal number.

-3 + 0.25 = - 3.25

Therefore, the decimal equivalent to -3 3/12 is -3.25

There is a bag filled with 6 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?

Answers

Answer:

Step-by-step explanation:

The first probability of it being red = 5/11

The key to the question is that you replace the red marble you took out. So there are still 5 red marbles.

You still have a 5/11 chance of getting a red marble.

P(red + red) = 5/11 * 5/11

Answer

P(red + red) = 25 / 121

SAS = side angle side

The order is important because the angles must be between the two congruent sides.

One pair of congruent sides is AC = CE as shown by the single tickmarks.

The other pair of congruent sides is BC = CD shown by the double tickmarks

The congruent angles are the vertical angles BCA and DCE. Vertical angles are always congruent. Note how these angles are sandwiched between the tickmarked sides.

Answer:

Step-by-step explanation:

We have the graph of the function f(x).

We want to determine which of the given is true of the graph from [tex]x=g[/tex] to [tex]x=\infty[/tex].

So, essentially, we are focusing on the last curve (see image below).

First, since the curve is above the x-axis, the curve is positive.

Second, since the curve is curving upwards, this means that it must be increasing. Another way to think about this is to think about the slope of our curve. While we can't calculate the exact slope, the average slope will be positive, so our function is increasing.

So, our answer is A.

And we're done!
