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.

Find the discrimnant. (No spam)
Answer:
76
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 ) , then the discriminant is
Δ = b² - 4ac
Given
3x² - 10x = - 2 ( add 2 to both sides )
3x² - 10x + 2 = 0 ← in standard form
with a = 3, b = - 10, c = 2 , then
b² - 4ac = (- 10)² - (4 × 3 × 2 ) = 100 - 24 = 76

“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

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)
