Paul surveyed students in a high school about their favorite sport of the 1, 200 students in the school, 67 tenth-grade students were surveyed. More than half of the 67 students said their favorite sport is basketball. Based on the survey, Paul concluded that the favorite sport of most high school students is basketball.
Why is Paul's conclusion incorrect?
1 Paul surveyed too many students.
2 Paul's survey sample only included tenth graders.
3 Paul did not survey any middle school students.
4 Paul did not include enough sports in the survey.
Answer:
2 Paul's Survey sample only included tenth graders
Step-by-step explanation:
The reson why this is your answer is simple
Because this is true, he ONLY surveyed tenth-graders. He should have found for all of the students, including the other 1,100 students that didn't get surveyed.

A scientist is growing bacteria, starting with a culture of 10 bacteria. The colony of bacteria doubles every 3 hours. Which equation represents the relationship between the number of bacteria (b) and the number of hours (t) that have elapsed?
A) B= 10(2)^t
B) B= 10(2)^t/3
C) B= 10(2)^3t
D) B= 10(e)^2t
E) B= log₂(t)
Answer:
B) B=10(2)^(t/3)
Step-by-step explanation:
The Formula used to find Exponential Growth is
[tex]y=a*b^{\frac{t}{t_{1} } }[/tex]
where y is the Final Amount
a is the Initial Amount
b is the Growth Factor
t is Time
t1 is Time to Complete one Growth
so for our Problem
a=10 and b=2 and t1=3 and y=B
so B=10(2)^(t/3)
So
The expression is
[tex]\\ \rm\rightarrowtail B=10(2)^{\frac{t}{3}}[/tex]
Option B is correct

A and B are two brothers. A weigh 50 kg and B weigh 45 kg. if they divide 285 g of roasted meat in the ratio of their weight, how many grams does each get?
Answer:
Share of A = 150 grams
Share if B = 135 grams
Step-by-step explanation:
Weight of A = 50 kg
Weight of B = 45 kg
ratio of weights = 50 : 45 = 10 : 9
Let the common multiplier of the ratio be x.
-> 10x + 9x = 285
-> 19x = 285
-> x = 285/19
-> x = 15
-> 10x = 150
-> 9x = 135
Share of A = 150 grams
Share if B = 135 grams

Answer: 16 cm
Step-by-step explanation:
By the triangle midsegment theorem, 2(ST)=2(8)=16=GF
The length of GF in the triangle illustrated will be 16cm.
How to compute the value?From the information given, the lengths of HT and T F are 6 centimeters, the lengths of HS and SG are 4 centimeters, and the length of ST is 8 centimeters.
Therefore, the length of GF will be:

3. Three Bean Salad Puzzle #2
A bean salad has 6 beans in all. It is made up of:
1/6 lima beans
1/3 red beans
1/2 black-eyed peas
How many of each type of bean is in the salad?
Answer: 1 lima bean, 2 red beans, 3 black-eyed peas
Step-by-step explanation:
If 1/6 of the beans are lima beans, then there are 6 * 1/6 lima beans in the salad. 6 * 1/6 = 6/6 = 1.
If 1/3 of the beans are red beans, then there are 6 * 1/3 red beans in the salad. 6 * 1/3 = 6/3 = 2.
If 1/2 of the beans are black-eyed peas, then there are 6 * 1/2 black-eyed peas in the salad. 6 * 1/2 = 6/2 = 3.
Answer:
Lima Beans: 6 x [tex]\frac{1}{6}[/tex] = 1
Red Beans: [tex]\frac{1}{3}[/tex] x 6 = 2

1. Trey just planted a small tree. He wanted to help it grow straight so he anchored the tree to the ground in three places using equal lengths of wire. The wires are tied to the tree 8 feet above the base of the tree. If Trey anchored each wire to the ground 6 feet from the base of the tree, what length of wire, in feet, is required for each anchor?
Answer:The correct answer is:
90 feet.
Explanation:
Each wire forms a right triangle with the tree and the ground. The height from the ground to the point on the tree the wire is attached to, 3 feet, is one leg. The length from the tree to where the wire is staked in the ground, 4 feet, is the other leg.
We use the Pythagorean theorem to find the hypotenuse: 3²+4²=c²; 9+16=c²; 25=c²; √25=√(c²); 5=c
This means each wire will be 5 feet long. There are 3 wires per tree, which gives us 5*3 = 15 feet. There are 6 tree, so this is 15*6 = 90 feet of wire.

please mark me as brainlist pleaseThe bearing of P from Q is 046º.
The bearing of R from Q is 124º.
QR = QP.
Work out the bearing of R from P.
Answer:
175°
Step-by-step explanation:
Bearing angles are usually measured clockwise from North. Reverse bearing angles differ from forward bearing angles by 180°. These relations and the usual angle sum relation for a triangle can be used to solve this problem.
Angle PQR will be the difference in the bearings from Q to P and Q to R:
∠PQR = 124° -46° = 78°
Triangle PQR is isosceles, so the base angle at P will be ...
∠QPR = (180° -78°)/2 = 51°
__
The bearing from P to R will be 51° less than the bearing from P to Q. The bearing from P to Q is 180° more than the bearing from Q to P.
PR bearing = PQ bearing - ∠QPR
= PQ bearing - 51°
= (46° +180°) -51° = 175°
The bearing of R from P is 175°.

Answer:
296.1 yards
Step-by-step explanation:
The surveyor is interested in solving a triangle with two sides and the enclosed angle known. The Law of Cosines is used for that purpose.
The angle interior to the triangle where the surveyor turned is the supplement of the turning angle:
180° -110° = 70°
The law of cosines tells us the relation of the given sides (a, b) and angle (C) to the unknown side (c) is ...
c² = a² +b² -2ab·cos(C)
c² = 245² +270² -2·245·270·cos(70°) ≈ 87675.7350
c ≈ √87675.7350 ≈ 296.10
The length of the lake is about 296.1 yards.
