Answer:
X=120
Step-by-step explanation:
It is an equalateral so all the angles in the middle are the same all being 60
The angle of a straight line is 180
So just minus 60 from 180 to get 120
180-60=120

Jason rolls a fair number cube labeled 1 through 6 and then he flips a coin what is the probability that he rolls a 3 and flips a head
There are 6 numbers on the cube.
The probability of getting a 3 would be 1 out of 6, 1/6
The probability of getting heads on a coin toss is 1/2
The probability of getting both a 3 and a head = 1/6 x 1/2 = 1/12
Answer: 1/12
Find the length of the third side. If necessary, round to the nearest tenth.
2
3
Answer:
The third side is 3.6
Step-by-step explanation:
Incomplete question;
The parameter from the complete question can be summarized as follows:
[tex]Side\ 1 =2[/tex]
[tex]Side\ 2 =3[/tex]
Required
Determine the third side (hypotenuse)
Let the third side be x;
So:
[tex]x^2 = Side\ 1^2 + Side\ 2^2[/tex]
[tex]x^2 = 2^2 + 3^2[/tex]
[tex]x^2 = 4 + 9[/tex]
[tex]x^2 = 13[/tex]
Take square roots of both sides
[tex]x = 3.6[/tex]
Two workers paint lines for angled parking spaces. One worker paints a line so that m∠1=65. The other worker paints a line so that m∠2=65. Are their lines parallel? Explain your answer.
The image of the car park showing the 2 angles is attached.
Answer:
Their lines are parallel.
Step-by-step explanation:
From the attached image, we can see that ∠1 and ∠2 form a pair of alternate exterior angles. Thus; ∠1 = ∠2.
Now since they are congruent, it means that their lines will be parallel.
Thus, we can conclude that their lines are parallel.

The table of values of the women's age to shoe size is presented as follows;
Women's Age and Shoe Size
[tex]\begin{array}{ccc} Age&&Shoe \, size\\18&&7\\30&&10\\52&&6\\64&&9\end{array}[/tex]
We get;
The correlation coefficient, r, is given as follows;
[tex]r = \dfrac{\sum \left(x_i - \overline x \right ) \cdot \left(y_i - \overline y \right )}{\sqrt{ \sum \left(x_i - \overline x \right )^2 \cdot \sum \left(y_i - \overline y \right )^2}}[/tex]
From MS Excel, we have;
[tex]\sum \left(x_i - \overline x \right ) \cdot \left(y_i - \overline y \right )[/tex] = 2
[tex]\sqrt{ \sum \left(x_i - \overline x \right )^2 \cdot \sum \left(y_i - \overline y \right )^2}[/tex] = √13,000 = 10·√130
∴ r = 2/(10·√130) ≈ 0.01754
Therefore, given that the calculated correlation coefficient, r is positive and less than 0.2 (weak), we have
The correlation is a weak and positive.

Step-by-step explanation:
Simplify 5√11-12√11-2√11
Applying,
The law of surd,
Step 1: factor out the common surd or irrational number i.e √11
√11(5-12-2)
√11(-9)
Step 2: Multiplying the whole number and the surd
-9√11
Therefore,
5√11-12√11-2√11 = -9√11
Hence the right option from the list of option is
c -9√11
Find the missing length of the triangle. 12 in 85 in.
Answer:
From Pythagoras Theorem
The square of the hypotenuse is equal to the sum of the squares of the other two sides
C² = 12² + 35²
C= √12²+35²
C= 37in
Answer:
side c = 37 in.
Step-by-step explanation:
side c is the hypotenuse as it is opposite of right angle (90 degree ).
12 and 35 are the two other smaller sides of the given right angles triangle.
using pythagoras theorem to find side c
a^2 + b^2 = c^2
12^2 + 35^2 = c^2
144 + 1225 = c^2
1369 = c^2
[tex]\sqrt{1369}[/tex] = c
37 = c

Use the definition of continuity and the properties of limits to show that’s the function…
Answer with Step-by-step explanation:
We are given that
[tex]g(x)=(x^2-3x-10)(x^2+2x^2-5x+4)[/tex]
x=-1
Using property of limit
[tex]\lim_{x\rightarrow -1}g(x)=\lim_{x\rightarrow -1}(x^2-3x-10)(3x^2-5x+4)[/tex]
=[tex](1+3-10)(3+5+4)[/tex]
=[tex](-6)(12)[/tex]
=[tex]-72[/tex]
[tex]g(-1)=(1+3-10)(1+2+5+4)[/tex]
[tex]g(-1)=(-6)(12)=-72[/tex]
[tex]\lim_{x\rightarrow -1}g(x)=g(-1)[/tex]
Hence, the function is continuous at x=-1

If this is the graph of f(x)=a^(x+h)+k then the domain is.....
Answer:
d)
Step-by-step explanation:
The domain are all the possible values for x. For this graph the domain will continue on forever in both the positive and negative direction, so (-∞, ∞).
The range are all possible values for y. For this graph, k affects the height of the graph. Since k affects how far up/ down you move the graph, therefore (k, ∞)
The h in the equation shows how far you move the graph to the left/right.

The conditional relative frequency table was calculated by row using data from a survey of one station’s television programming. The survey compared the target audience with the type of show, either live or recorded, over a 24-hour time period.
A 4-column table with 3 rows titled television programming. The first column has no label with entries adult, children, total. The second column is labeled live with entries 0.625, 0.5, nearly equal to 0.583. The third column is labeled recorded with entries 0.375, 0.5, nearly equal to 0.417. The fourth column is labeled total with entries 1.0, 1.0, 1.0.
Which is the best description of the value 0.375 in the table?
Given that the program was targeted at adults, there is a 37.5% chance that it was recorded.
Given that the program was recorded, there is a 37.5% chance that it was targeted at adults.
37.5% of the programs are targeted at adults.
37.5% of the programs are recorded.
Answer:
37.5% of the programs are targeted at adults
Step-by-step explanation:
The following figure shows the given four column table for the target audience of television programming
[tex]\begin{array}{lllc}&Television \ Programming \\& Live&Recorded&Total\\Adult&0.625&0.375&1.0\\Children&0.5&0.5&1.0\\Total&\approx 0.583& \approx 0.417&1.0\end{array}[/tex]
From the table, we have that the best description of the value 0.375 in the table is that the percentage of television program targeted at adults is 37.5%
Answer:
The answer is a “Given that the program was targeted at adults, there is a 37.5% chance that it was recorded”

dude its just 3 rooms. yes
Answer:
3 rooms
Step-by-step explanation:
For 1 1/4 rolls of electric wire = 1 room
For 3 3/4 rolls of electric wire = 3 3/4 ÷ 1 1/4
= 15/4 ÷ 5/4
= 15/4 x 4/5
= 15/5
= 3 rooms
What is the area of triangle ABC?
3 square units
O 7 Sguare units
11 square units
15 square units
Answer:
3
Step-by-step explanation:
base = 4-1
= 3
height = 3-1
= 2
Area = 1/2 (b)(h)
= 1/2 (3)(2)
= 3
therefore the answer is 3 square unit
Use numerals instead of words
Answer:
Step-by-step explanation:
Put in the 3 and 4 so it is the square root of 3^4 - -6^2
The square root of 3^4 + 6^2
The square root of 3^4 is 3^2 so
9 + 6^2
=> 9 + 36
=> 45
45 in numerals is XLV
Put these numbers in order from greatest to least.

Jamal puts $100 in an account that does not earn any interest. Every month after that, he deposits the same amount of money. This sequence represents his account balance for the first few months. $100, $125, $150, What is the explicit formula in function form for the amount of money in his account at the beginning of month n?
Answer:
Tn = 75+25n
Step-by-step explanation:
The balance are in arithmetic progression
$100, $125, $150...
The formula for calculating the nth term of the sequence is expressed as;
Tn = a+(n-1)d
a =100
d = 125 - 100 = 150 - 125
d = 25
n is the number of terms
Substitute
Tn = 100+(n-1)*25
Tn = 100 + 25n-25
Tn = 75+25n
Hence the nth term of the sequence is Tn = 75+25n
