Answer:
The 4 possible outcomes are HH, HT, TH, TT.
So theoretically, HH should occur 1in 4 times.
1/4 = x/20
x = 5
So why is it actually 2 in 20 when theoretically it should be 5 in 20? One reason is that theoretical probabilities gain more accuracy with larger numbers of results (e.g tossing the coins 100 times). You can likely think of some more reasons.

Answer: 15,17,19,21,23
Step-by-step explanation:
You can let the middle number = x, then the numbers are
x-4, x-2, x, x+2, x+4
Plugging it back in to what is given,
x-4+x-2+x = 7+x+2+x+4
3x-6 = 2x + 13
x = 19
The numbers are 15, 17, 19, 21, 23

A student claims that the expression “9 times the sum of a number and 13” is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answer: The student is wrong. The correct algebraic expression is 9(n + 13)
The algebraic expression is represented as follows:
The sum of a number and 13 is represented as follows:
Let
n = the number
Therefore,
The sum of a number and 13 is:
n + 13
9 times the sum of a number and 13” can be translated as follows:
9(n + 13)
Therefore, the student is wrong.

A triangle has side lengths of 17 cm and 7 cm. Which could be the value of the third side, 28 cm or 19 cm?
Answer:
19 cm
Step-by-step explanation:
Triangle Inequality Theorem:
The sum of two side lengths of a triangle is always greater than the third side.
17+7> 19 17+7 IS NOT BIGGER THAN 28
17+19>7
7+19>17
Answer:
19 cm me thinks
Explanation:
it has to be equivalent to the other side
Is 36 T-shirts in 3 boxes equivalent to 60 T-shirts in 6 boxes?
Answer:no it is not equivalent
Step-by-step explanation:
36x3=108 so there is 108 shirts in that box
60x6=360 so 360 is in that box
so not equivalent because they have different amounts in the boxes one is more and the other one less
your welcome
Answer:
No
Step-by-step explanation:
Since the unit rates 12 t-shirts/1 box
and 10 t-shirts/1 box are not the same, the rates are not equivalent.

[tex]\huge{\left[\begin{array}{cc}94 \text{ percent brown}&6 \text{ percent black}\\42 \text{ percent brown}&58 \text{ percent black}\end{array}\right]}\\ \huge{\text{ which signifies that the black variation}}\\ \text{ was much better suited for survival}[/tex]
Step-by-step explanation:
To solve for percentages, simply divide the given group by the total.
i.e.,
188/200 = 94% of grasshoppers have brown bodies at the start, and
12/200 = 6% of grasshoppers have brown bodies at the start
Then, for the end
147/350 = 42% of grasshoppers have brown bodies at the end, and
203/350 = 58% of grasshoppers have black bodies at the end.

A tank was filled with 350 gallons of water. Then a crack developed and 18% of the water leaked out of the tank before it could be repaired. How much water leaked out of the tank?
Answer:
its 63 if i'm wrong sorry
Step-by-step explanation:
but what you do is 350 X 18% to get 63
Answer:
63 gallons
Step-by-step explanation:
Question: What is 18 percent of 350?
Percentage solution with steps:
Step 1: Our output value is 350.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, $350 = 100%.
Step 4: Similarly, x = 18%.
Step 5: This results in a pair of simple equations:
350 = 100%(1).
x = 18% (2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
350/x = 100%/18%
Step 7: Again, the reciprocal of both sides gives
x/350=18/100
⇒ x = 63
Therefore, 18% of 350 is 63.
