Answer: 81%
Step-by-step explanation:
From the question, we are informed that a student received the following test scores: 71%, 89%, 72%,
84% and 83% in 5 tests and the student wants to maintain an average of 80%.
The lowest score/grade they can receive on the next test to maintain at least an 80% average first thus:
First, to make it easy we can remove the percent sign. Then we multiply 80 by 6 since we're calculating for 6 tests scores. This will be:
= 80 × 6
= 480
We then add all the 5 test scores. This will be:
= 71 + 89 + 72 + 84 + 83
= 399
We then subtract the values gotten. This will be:
= 480 - 399
= 81
This means the student must get at least 81%

Given f(x) = 3x- 1 and g(x) = 2x-3, for which value of x does g(x) = f(2)?
Options:
A)x=3/2
B)x=2
C)x=5/2
D)x=4
Answer: x = 4
Step-by-step explanation: f(2) = 3(2)-1 = 5. Meaning x needs to be a value that makes g(x) = 5. You can set them up equal to each other 5 = 2x-3 and solve. You end up getting x = 4.

The diameters of cherry tomatoes produced by a large farm have an approximately Normal distribution, with a mean diameter of 22 mm and a standard deviation of 2.5 mm. What proportion of such tomatoes have a diameter between 20 and 26 mm?
Answer:
0.7333
Step-by-step explanation:
2021 Math
Proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.
What is standard deviation?It's a way to measure how far each data point is spread from the average value.
let x represents the diameters of cherry tomatoes produced by large farm which is formally distributed with mean = 22m
and, standard deviation= 2.5 mm
Now, proportion of tomatoes have diameter between 20 and 26 mm
=P (20 < x< 26)
=P(20-22 / 2.5 < [tex]x- \mu/ \sigma[/tex] < 26- 22/2.5)
=P(-0.8 < z < 1.6)
=P(z = 1.6) - P(z=-0.8)
=0.9452 - 0.2119
==0.7333
Hence, proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.

Write 28 + 24 as a product of 2 factors using the GCF and the distributive property.
Answer:
4(7 + 6)
Step-by-step explanation:
The GCF (greatest common factor) is the largest factor that both numbers share, and in this case it is 4.
28+24 as a product of 2 factors using the GCF and the distributive property is 4(7+6)
What is Number system?A number system is defined as a system of writing to express numbers.
We need to write 28 + 24 as a product of 2 factors using the GCF and the distributive property.
A factor is a number that divides another number, leaving no remainder
The greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.
We need to find factors 28 and 24
28=1,2,4,7,14,28
24=1,2,3,4,6,8,12,24
4 is the greatest common factor.
28 + 24
Take 4 as common
4(7+6)
Hence, 28+24 as a product of 2 factors using the GCF and the distributive property is 4(7+6)

Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.

“Identify the CORRECT formula based on the sequence” do not answer on some bs .
Answer:
see explanation
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
21 ÷ 7 = 63 ÷ 21 = 3
this indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ration
here a₁ = 7 and r = 3 , then
[tex]a_{n}[/tex] = 7 . [tex]3^{n-1}[/tex] ← explicit formula
the recursive formula allows a term to be found by multiplying the previous term by r , then
