Answer:
a) 34.3%
b) 49%
Step-by-step explanation:
In order to find the probability of a sequence of events, we need to multiply each individual probability by the others in decimal form. Therefore, we need to turn these probabilities into decimal form by dividing them by 100 like so..
70% / 100 = 0.70
Now we multiply all of them together and multiply the product by 100 to get the percentage.
0.70 * 0.70 * 0.70 = 0.343
0.343 * 100 = 34.3%
34.3% is the probability of it raining on all three days. Now to find the probability of it raining on two consecutive days we do the same but multiply only 2 probabilities
0.70 * 0.70 = 0.49
0.49 * 100 = 49%

Salvador sold hats during a weekend sporting event. On Saturday, Salvador sold 47 of the total number of hats. On Sunday, he sold 14 of the total number of hats. What fraction of the total number of hats was left over
Answer:
[tex]\frac{x - 61}{x}[/tex]
Step-by-step explanation:
Let x = total number of hats sold
hat left after sales = x - (47 + 14 ) = x - 61
x - 61 / x
what is the missing term of ..9, __ , 19
Answer:
The answer could be anything, but if it's an arithmetical sequence, then it's 14.
Step-by-step explanation:
I'm assuming that the added numbers always stay the same, meaning it's linear. If you add 5 to 9, you get 14. If you add 5 again, you get 19. Another way of doing this is (19-9)/2 = 5, then 9+5=14.

Answer:
angle 11 they are vertically opposite.
∠11 must also be 85 degrees.
What are vertically opposite angles?Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal. They are referred to as vertical angles at times.
As per the given data:
∠9 = 85°
From the diagram, ∠9 and ∠11 are vertically opposite angles.
∴ ∠9 = ∠11
∠11 must also measure 85°.

Please help parts b and c
Answer:
a = 2
b = 4
c = 8
Step-by-step explanation:
Remember the relationship:
[tex](a^{x})^{y} = a^{x*y}[/tex]
First, in "a" we have:
a) [tex]8^{1/3} = \sqrt[3]{8} = 2[/tex]
then in the next ones, we can use the result that we obtained in the part a:
b) [tex]8^{2/3} = (8^{1/3})^2 = (2)^2 = 4[/tex]
Now we can do exactly the same in c:
c) where first we need to know that:
2*2*2*2 = 4*4 = 16
then:
2^4 = 16
then:
[tex]\sqrt[4]{16} = 16^{1/4} = 2[/tex]
Now let's solve the problem:
[tex]16^{3/4} = (16^{1/4})^3 = (2)^3 = 2*2*2 = 8[/tex]
A building is 200 feet high. One end of a wire is attached to the top of the building.
The other end is attached to the group 150 feet away from the base of the building. How
long is the wire?
Answer:
250 feet
Step-by-step explanation:
If you draw out this situation, you would get a right triangle with a height of 200 (feet) and a base of 150 (feet). The wire is the missing length, or the 'hypotenuse' of this right triangle. You use the pythagoras thingie, and the formula is a^2 + b^2 = c^2.
a= 200
b= 150
c= ?
40,000 + 22,500 = c^2
62,500 = c^2
c = √62,500
∴ c = 250
ABCD shows the original location of a shape. FGHI shows the shape reflected across a
vertical line. If the length of side AB is 5.8 units, and the length of side CD is 8.1 units,
what is the length of side FG?
B
D
O A 5.8 units
OB. 8.1 units
OC. 11.3 units
OD
13.9 units
Answer:
A. 5.8
Step-by-step explanation:
if ABCD was reflected to FGHI means that A became F and B became G so AB became (was mapped to ) FG after reflection.
the length ( or distance) after reflection is is preserved ( does not change) so
if AB = 5.8 units then FG =5.8 units.

Kelvin finds a tile shaped like a triangle. He measures its angles to discover that it has two acute angles and one right angle. What type of triangle did Kelvin find obtuse triangle, acute triangle or right triangle?
Answer:
right triangle
Step-by-step explanation:
A Right triangle is a triangle that has one of its angle as 90°.
Since the triangular shaped tiles has a right angle, the kind of triangle Kevin found will be a right triangle.
A right triangle has two acute angles (angles less than 90°) and a right angle

How many 5/6 are in 2/3
Answer:
The amount is 4/5 of 5/6 is in 2/3.
Step-by-step explanation:
There 4/5 is 5/6 in the fraction 2/3 which is determined by the division operation.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
For example 4/2 = 2
We have to determine how many 5/6 are in the fraction 2/3.
The numbers are given in the question below
2/3 and 5/6
According to the given question, the required solution would be as:
⇒ 2/3 ÷ 5/6
⇒ (2/3) / (5/6)
Reciprocal the terms of the numerator in the above expression
⇒ (2/3) × (6/5)
Apply the multiplication operation,
⇒ 12 / 15
Reduce the fraction in the simplest form,
⇒ 4/5
Therefore, there 4/5 is 5/6 in the fraction 2/3.

Write an equation in slope-intercept form perpendicular to the given equation through the given point
Y = -3x + 4
(6,-2)
Answer:
The equation in slope-intercept form perpendicular to the given equation [tex]y = -3x + 4[/tex] through the given point (6,-2) is [tex]\mathbf{y=\frac{1}{3}x}[/tex]
Step-by-step explanation:
We need to write an equation in slope-intercept form perpendicular to the given equation through the given point
y = -3x + 4
(6,-2)
The general equation in slope intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding slope:
The given line is perpendicular to required line, so there slopes are opposite
The slope of given line [tex]y = -3x + 4[/tex] is m = -3, (By comparing it with general equation y=mx+b, we get m = -3)
The slope of required line is: [tex]m = \frac{1}{3}[/tex]
Finding y-intercept:
y-intercept can be found by using slope [tex]m = \frac{1}{3}[/tex] and the point(6,-2)
[tex]y=mx+b\\-2=\frac{1}{3}(-6)+b\\-2=-2+b\\b=-2+2\\b=0[/tex]
So, we get y-intercept b =0
Equation of required line:
So, the equation of required line having slope [tex]m = \frac{1}{3}[/tex] and y-intercept b =0 is:
[tex]y=mx+b\\y=\frac{1}{3}x+0\\y=\frac{1}{3}x[/tex]
So, the equation in slope-intercept form perpendicular to the given equation [tex]y = -3x + 4[/tex] through the given point (6,-2) is [tex]\mathbf{y=\frac{1}{3}x}[/tex]
Determine the intercepts of the line.
y=8x - 18
y-intercept:
x-intercept:
Answer:
y-intercept: -18
x-intercept: 9/4
Step-by-step explanation:
Substitute x = 0, we find that y = -18 i.e. the y-intercept is -18.
Substitute y = 0, we find that x = 9/4 i.e. the x-intercept is 9/4.
