Answer:
the classmark of the class is 162.5
Step-by-step explanation:
The computation of the class mark is shown below:
Given that
160 - 165
So, the class mark of the class is
= (Upper limit + lower limit) ÷ 2
= (160 + 165) ÷ 2
= 162.5
Hence, the classmark of the class is 162.5

A pollster surveys 80 people to determine whether they will vote for Seth Gleason for mayor. 42 out of 80 say yes. What is the experimental probability that the next person surveyed will say he or she plans to vote for Seth Gleason?
Answer:
42 out of 80
Step-by-step explanation:
Given function:
surveys 80 people42 votedto find the experimental probability that the next person surveyed say yes or no..Thinks:
42 out of 80 means 42:80 in ratio formif 42:80 that they’ll vote for Seth Gleason then this means that the next person have 42:80 chance to vote for Seth Gleaso...Forms:
0.525 42/80.. simplify form=21/40. 52.5%Therefore, the percentage the next person would vote for Seth Gleason is a percentage of 52.5% and also have a ratio of 42:80.
two complentary angles are drawn such that one angle is 10 more than seven times the other angle find the measure of each angle
Answer:
10° and 80°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other angle is 7x + 10 , so
x + 7x + 10 = 90
8x + 10 = 90 ( subtract 10 from both sides )
8x = 80 ( divide both sides by 8 )
x = 10
and 7x + 10 = 7(10) + 10 = 70 + 10 = 80
Thus the 2 angles are 10° and 80°

Factor the expression using the GCF. 58+28=
Answer:
2(29+14)
Step-by-step explanation:
Given function:
To find the GCF of 58+28..Find the GCF of 58+28:
[tex]58=29[/tex]·[tex]2[/tex] [tex]28=14[/tex]·[tex]2[/tex]Rewrite:
[tex]2(29+14)[/tex]Therefore, using GCF, the new expression would be 2(29+14)..
The expression 58 + 28 can be factorized as 2 (29 + 14).
What is GCF?GCF which is the abbreviated form for Greatest Common Factor of two numbers, as the name implies, is the greatest common factor of both the numbers.
GCF of two numbers can be found using prime factorization.
Given the expression 58 + 28.
To find the GCF of two numbers, list the prime factors of these two numbers.
58 = 2 × 29
28 = 2 × 14 = 2 × 2 × 7
The only common factor is 2.
So the greatest common factor is 2.
58 + 28 = (2 × 29) + (2 × 14)
Taking the common factor of 2 outside the brackets,
58 + 28 = 2 (29 + 14)
Hence the expression 58 + 28 can be factorized as 2 (29 + 14) using the greatest common factor.

For what value of q is the equation -13(q + 4) = 7q + 16
Answer:
Q = -3.4
Step-by-step explanation:
Our original equation is: -13(q+4)=7q+16
if we simplify this, we get: -13q-52=7q+16
Subtract 16 from both sides: -13q-68=7q
Add 13q to both sides to get: -68=20q
divide the equation to get this: -3.4=q

Marty and Adam want to share 8/10 feet of rope, equally. What amount of rope should each person get?
Answer: 2/5 feet
Step-by-step explanation:
From the question, we are informed that Marty and Adam want to share 8/10 feet of rope, equally.
The amount of rope that each person would get would be calculated by dividing 8/10 by 2. This will be:
= 8/10 ÷ 2
= 8/10 × 1/2
= 8/20
= 2/5
Therefore, each person gets 2/5 feet of rope.
