Explanation:
There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.
If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.
The empirical probability of it not raining on the first of May is therefore...
1 - (probability it rains)
1 - (3/10)
(10/10) - (3/10)
(10-3)/10
7/10
We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.

James has decided to start saving for a cruise over the summer. His money is
currently in the local bank, modeled by the function s(x) = 102. He is able to do work
around the neighborhood to earn extra money and that function would be a(x) = 8
+ 2), where x is measured in hours. Explain to James how he can create a function
that combines the two, and describe any simplification that can be done.

20
25
Answer:
15
Step-by-step explanation:
hypotenuse (h) = 25
perpendicular (p) = 20
base (b) = ?
we know by using Pythagoras theorem we get
b = √h² - p²
= √25² - 20²
= √225
= 15
Help me plz this stuff is hard
Answer:
[tex]x = 25.9[/tex]
Step-by-step explanation:
Apply law of sines.
[tex] \frac{23}{ \sin(22) } = \frac{x}{ \sin(25) } [/tex]
[tex] \frac{23}{ \sin(22) } \times \sin(25) = x[/tex]
[tex]x = 25.9[/tex]
Answer:
25.9
Step-by-step explanation:
By sine rule:
[tex] \frac{BC}{ \sin 25 \degree} = \frac{23}{ \sin 22 \degree} \\ \\ BC = \frac{23 \sin 25 \degree}{ \sin 22 \degree} \\ \\ BC = \frac{9.72022002}{ \sin 22 \degree} \\ \\BC = 25.947808156 \\ \\ BC \approx \: 25.9[/tex]

Andrew drives through 5 intersections with stoplights on his way to work. He
records that he is stopped by a red light in 2 of the 5 intersections. If he uses
this as his general probability of getting stopped at a red light on his way to or
from work, how many times can he expect to be stopped at a red light over the
next 40 times he drives through an intersection on his route?
Andrew should expect to be stopped
times.
Answer:
16 times

Answer:
46 degrees
Step-by-step explanation:
You should know that measures QRS, which form a horizontal line, measures up to 180 degrees. (Just like a right angle adds to 90 degrees). So, TRS is 42 degrees and URT is 92 degrees, that would make QRU measure 46 degrees because 180 - 92 - 42 = 46 degrees.
Hope that helps you!! Please give me brainliest!! ;)
Answer:
42°
Step-by-step explanation:
A horizontal, or flat line is 180°. This means the total measures of ∠TRS, ∠URT, and ∠QRU, are 180°. We can subtract the given measures from 180 to find the measure of ∠QRU.
∠TRS = 42°
∠URT = 92°
Subtract 42 and 92 from 180.
180 - 42 - 92 = 46
∠QRU = 42°
m∠QRU in circle R is 42°.
Good luck ^^
find x to the nearest tenth
The value of the base length x of the right angle triangle to the nearest tenth is 18.4.
What is the value of x?From the diagram;
Angle θ = 49°Hypotenuse = 28Base length x = ?We use trigonometric ratio since its right angle triangle.
Cos = Adjacent / Hypotenuse
Cosθ = Base length / Hypotenuse
Cos( 49° ) = x / 28
x = Cos( 49° ) × 28
x = 0.656059 × 28
x = 18.4
Therefore, the value of the base length x of the right angle triangle to the nearest tenth is 18.4.

Help please. It’s geometry and it asks to find the shaded region.
Answer: (a)
Step-by-step explanation:
Given
The diameter of the inner circle is [tex]d=14\ m[/tex]
thickness of the strip is [tex]t=2\ m[/tex]
So, the radius of inner circle is [tex]r=7\ m[/tex]
Radius of the outer circle [tex]R=7+2=9\ m[/tex]
Area of the shaded region is the difference of the area of outer circle and inner circle.
[tex]\Rightarrow \pi R^2-\pi r^2\\\Rightarrow \pi (9^2-7^2)\\\Rightarrow 3.142\times 32\\\Rightarrow 100.5\ m^2[/tex]
hence, option (a) is correct.
6.
A softball pitcher throws a softball to a catcher behind home plate. The softball is 3 feet above the ground when it leaves the pitcher's hand at a velocity of 50 feet per second. If the softbal's acceleration is - 16
Ft/s2. This can be modeled with the equation (h=height, t=time) h(t)=16t^2 +50t+ 3
What is the time at which the softball would hit the ground it it were not hit or caught?
A.) .5 seconds
B.)3.12 seconds
c.) 3.18 seconds
D. ) 2.42
Answer:
Using their equation and the fact that the ball will fall 3 ft before reaching the ground:
3 = 16 t^2 + 50 t + 3 represents the given situation
16 t^2 + 50 t = t (16 t + 50) = 0
16 t + 50 = 0
t = 50 / 16 = 3.12 sec
write in sigma notation 3+10+17+24+31

I WILL GIVE BRAINLIEST!!!!!!! A video game developer wants to know how long it takes people to finish playing their new game. They surveyed a random sample of 13 players and asked how long it took them (in minutes). 1.235 952 457 1,486 1,486 | 1,759 1,148 548 1,0371,864 | 1,245 866 1,431 a. Estimate the median time it will take all players to finish this game. minutes b. Find the interquartile range for this sample minutes
Answer:
a) median = 1,148 minutes
b) IQR = 549.5
Step-by-step explanation:
Q1 = (952 + 866) / 2 = 909
Q3 = (1431 + 1486) / 2 = 1458.5
IQR = 1458.5 - 909.0 = 549.5

A card is drawn from a standard deck of cards. What is the probability

A card is drawn from a standard deck of cards. What is the probability that a spade is drawn, NOT replaced, and another spade is drawn?
Answer:
With replacement
[tex]probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}[/tex]
[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement =[/tex][tex]\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}[/tex]
Without replacement
[tex]probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}[/tex]
[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement = \frac{1}{4} \times\frac{4}{17} =\frac{1}{17}[/tex]
