Calculate the probability P(E).
The Heavy Weather Service predicts that for tomorrow there is a 50% chance of tornadoes, a 25% chance of a monsoon, and a 15% chance of both. What is the probability that we will be lucky tomorrow and encounter neither tornadoes nor a monsoon?
Answers
The probability that we will be lucky tomorrow and encounter neither tornadoes nor a monsoon is 0.85
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total putcome
If there is a 15% chance that tornadoes and monsoon will occur, hence the
the probability that we will be lucky tomorrow and encounter neither tornadoes nor a monsoon will be expressed as:
Pr(neither tornadoes nor a monsoon) = 1 - Pr(both will occur)
Pr(neither tornadoes nor a monsoon) = 1 - 0.15
Pr(neither tornadoes nor a monsoon) = 0.85 = 85%
Hence the probability that we will be lucky tomorrow and encounter neither tornadoes nor a monsoon is 0.85

A recipe calls for 1 1/8 cups of flower for every 3/4 cup of sugar used. How many cups of flour are needed for each cup of sugar used?
A 1 1/2
B 1 5/27
C 27/32
D 3/4
Answers
Answer: A
You could put this in a ratio of flour to sugar 9/8 : 3/4. If we need to find out how many cups of flour are required for each cup of sugar, then we’ll need to divide both sides by 3/4 to get to 1 cup of sugar so that we can find how many cups of flour are required for this amount. The flour is 9/8 cups which then gets divided by 3/4 and is 1/2 so this is our answer.
what is the equation of the line in the slope-intercept? write your answer in simplest form.
Answers
Answer:
y=-6x
Step-by-step explanation:
Slope intercept form is y=mx+b where b is the y intercept and m is the slope. In this particular example, the y intercept is at (0,0), the origin, so b=0. y=mx+0 or just y=mx. Now, to determine the slope, we must look at the graph. It appears the graph intersects the point (-10, 60) as well as the point (0,0). Other than just calculating it quickly in your head, the way to get slope from that is y1-y2/x1-x2. Setting that up, 60-0/-10-0, which is 60/-10, which is equal to -6. Put that into the equation and you get y=-6x

Answer:
m∠A=88°
Step-by-step explanation:
∠ABC=∠ACB=46° (base angles of isos triangle)
∠BAC=180°-46°-46° (angle sum of triangle)
=88°
Therefore, in the triangle from the picture, m
Now applying the Triangle Sum Theorem, all interior angles of a triangle must sum up to 180°.
Therefore, m
We can create an Algebraic equation to find the angle measure of angle A because we know the angle measures of angles B and C, and we know all three angles must sum up to 180°.
46+46+x=180
x = the measure of angle A
92+x=180
92-92+x=180-92
x=88
Therefore, the measure of angle A is 88°.

2. Since both numbers are negative, the product is positive. Multiply both numerators together. Multiply both denominators together.
= 253/20
253 is the product of 2 prime numbers, 11 and 23. 20 is the product of 2² and 5. There are no common factors in the numerator and denominator, so this fraction cannot be reduced.

what are the correct answers whoever answers it correctly gets brainlist
Answers
Answer:
So the answer is... Hold on... Ok i did my research and the answer is........
Step-by-step explanation:
1. Economic
The Industrial Revolution stimulated the hunt for colonies. First, colonies provided raw
materials. Second, colonies served as a market for surplus manufactured goods.
2. Political
Every country wanted national hegemony – that is, to be the No. 1 imperialist country in the
world. To achieve this, they wanted to control as much of the world as
possible. The nation’s greatness is measured by the quality and quantity
of its colonies. Folks wanted to plant the flag in as many places as
possible. Every country wanted recognition as a world power. They
wanted to improve their reputation among other European countries.
They wanted to increase their political power and prestige. Every country
was in competition with its rivals. You took territory – simply to prevent
your rival from getting it!
3. Military
Every imperialist country was worried about its own national security: The competition
among imperialist powers was vicious. One had to protect one’s own
country and its colonies. Every country wanted to gain military
advantage over its rivals. A colony could serve as a fueling station for
the Navy. A ship could stop and load up on supplies. Some spots in the
world, especially waterways, were strategically important. The Navy
was paramount: It must have freedom to travel to and from the
colonies.
4. Cultural
Social Darwinism was the prevailing belief in Europe. It explained why some countries were
rich and some were poor. People compete for survival. The strong survive.
The rich were naturally superior. The weak were unfit. Poverty was a sign of
being unfit. The poor were naturally inferior. The European colonizers were
the Superior Races. The African and Asian colonized were Inferior Races. The
Europeans regarded themselves as racially and culturally superior to the people
of Africa and Asia. Humanitarians argued that it was Europe’s noble duty to
uplift and enlighten the backward peoples. Belief in Anglo-Saxon superiority
was prevalent.
5. Religious
The “missionary impulse”: Christianity is superior to all other religions. We must
spread Christianity to Asia and Africa. Religion encouraged imperialism. People
felt they needed to acquire territory in order to Christianize people. A serious
moral issue – Christianity is in direct conflict with Social Darwinism. Under
Christianity, all people are equal in God’s eyes. Under Social Darwinism, the
Europeans are superior and the Africans and Asians are inferior. There was also a
certain element of hypocrisy: While the Europeans spoke of uplifting people, they
were actually motivated by profit and greed.

a
9.96p − 10.01p ≤ 50, so p ≤ 1
