it's the only one tht adds to 180
Answer:
49°, 59° and 72°
Step-by-step explanation:
Interior angles are supposed to add up to 180°
49+59+72=180° (correct set)
34+45+11= 90° (not correct set)
24+51+15= 90° (not correct set)
45+70+85 = 200° (not correct set)
hence the correct set is 49°, 59° and 72°

The mean breaking strength of a ceramic insulator must be at least 10 psi. The process by which this insulator is manufactured must show equivalence to this standard. If the process can manufacture insulators with a mean breaking strength of at least 9.4 psi, it will be considered equivalent to the standard. A random sample of 50 insulators is available, and the sample mean and standard deviation of breaking strength are 9.22 psi and 0.24 psi, respectively. a. State the appropriate hypotheses that must be tested to demonstrate equivalence.

H0 : u ≥ 10 against the claim Ha: u < 10
Step-by-step explanation:
The mean breaking strength of a ceramic insulator must be at least 10 psi.
(At least means greater or equal to ). As it is already given in the data the null and alternate hypotheses will be formulated according to it.
H0 : u ≥ 10 against the claim Ha: u < 10
The null hypothesis is the mean breaking strength of a ceramic insulator must be at least 10 psi
and the alternate hypothesis is
the mean breaking strength of a ceramic insulator is less than 10 psi

vertical stretch by a factor of 2; left shift 2 units
Step-by-step explanation:
The transformation ...
g(x) = a·f(b(x -c)) +d
does the following:
vertical stretch by a factor of 'a'horizontal compression by a factor of 'b'translation right by 'c' unitstranslation up by 'd' unitsFor many functions, horizontal coordinate changes are indistinguishable from vertical coordinate changes. Exponential functions tend to be one of those.
__
Using the above notation, you seem to have f(x) = 3^x, and g(x) = 2f(x+2). The transformation is a vertical stretch by a factor of 2, and a translation left 2 units.
__
As with all exponential functions, ...
the domain is "all real numbers"the range is all numbers above the asymptote: f(x) > 0the horizontal asymptote is f(x) = 0The function is a growth function, so ...
x → -∞, f(x) → 0x → ∞, f(x) → ∞_____
Additional comment
The left shift is equivalent to an additional vertical stretch. The function could be rewritten as ...
f(x) = 18(3^x)
with no left shift and a vertical stretch by a factor of 18 instead of 2.

A motorboat leaves a harbor and travels at an average speed of 8 mph toward a small island. Two hours later a cabin cruiser leaves the same harbor and travels at an average speed of 16 mph toward the same island. In how many hours after the cabin cruiser leaves will the cabin cruiser be alongside the motorboat
Answers
Answer:
2 hours.
Step-by-step explanation:
From the question given above, the following data were obtained:
Speed of motorboat (sₘ) = 8 mph
Speed of cabin cruiser (s꜀) = 16 mph
From the question given, we were told that the cabin cruiser started his journey 2 hours later after the motorboat has left.
Let t be the time for the cabin cruiser.
Thus, the time for the motorboat will be (2 + t)
Also, if the cabin cruiser and the motorboat must be along side each other, then their distance must be the same.
With the above information, we can obtain the time taken for the cabin cruiser and the motorboat to be along side each other. This can be obtained as follow:
Speed of motorboat (sₘ) = 8 mph
Time for motorboat (tₘ) = t + 2
Speed of cabin cruiser (s꜀) = 16 mph
Time for cabin cruiser (t꜀) = t
Distance of motorboat = distance of cabin cruiser
Recall:
Distance = speed × time
Therefore,
sₘ × tₘ = s꜀ × t꜀
8 × (t + 2) = 16 × t
Clear bracket
8t + 16 = 16t
Collect like terms
16 = 16t – 8t
16 = 8t
Divide both side by 8
t = 16 / 8
t = 2 hours
Thus, it will take 2 hours for the cabin cruiser and the motorboat to be along side each other.
Find the length of AB?
Answers
Given:
The figure of a right triangle.
To find:
The length of AB.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
Using this trigonometric ratio for the given triangle, we get
[tex]\cos A=\dfrac{AB}{AC}[/tex]
[tex]\cos (60^\circ)=\dfrac{AB}{10}[/tex]
[tex]\dfrac{1}{2}=\dfrac{AB}{10}[/tex]
[tex]\dfrac{1}{2}\times 10=AB[/tex]
[tex]5=AB[/tex]
Therefore, the length of AB is 5 units.

Recipe: Makes 30

60 g sugar
180 g flour
Answers
Answer:
24 g butter
12 g sugar
36 g flour
Step-by-step explanation:
The recipe makes 30 shortbread fingers.
She wants to make 6 fingers.
6/30 = 1/5
She wants to make 1/5 of the recipe, so she needs 1/5 of each ingredient's amount.
Divide each amount by 5.
Recipe:
Makes 30 30/5 = 6 Makes 6
120 g butter 120/5 = 24 24 g butter
60 g sugar 60/5 = 12 12 g sugar
180 g flour 180/5 = 36 36 g flour

y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2-x_{1} } }[/tex]
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = [tex]\frac{0-6}{3-0}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2
The line crosses the y- axis at (0, 6 ) ⇒ c = 6
y = - 2x + 6 ← equation of line

Gabriella can line up her textbooks in 24 different ways on her bookshelf.
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Given that;
Gabriella has a Spanish book, a biology book, physics book, and a health text book.
We have;
She has a total of 4 books in her book shelf.
So, the number of positions in which the books have to be put are four.
As we can see,
The books are only one in number each. So, the choices are not repeatable.
So, In first position we have four choices, in third we will be left with three choices, in the seconds position we will have a total of two books as choice and in the last positive we have to put the book that is left.
So, the total different ways in which she can line up her books in the bookshelf are,
= 4×3×2×1
= 24
Thus, There are 24 different ways possible.
