Answer:
1 (give brainliest plss)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 5 • -8 = -40
Step-2 : Find two factors of -40 whose sum equals the coefficient of the middle term, which is -3 .
-40 + 1 = -39
-20 + 2 = -18
-10 + 4 = -6
-8 + 5 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 5
5x2 - 8x + 5x - 8
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (5x-8)
Add up the last 2 terms, pulling out common factors :
1 • (5x-8)
Step-5 : Add up the four terms of step 4 :
(x+1) • (5x-8)
Which is the desired factorization

Actually Welcome to the concept of Quadratic Equations.
Degree of a equation represents the highest power of the varible in the equation, For quadratic equation the degree is 2.
Leading Coefficient are the constant numbers that are significantly multiplied with the variables in the equation.
==> 5x^2 - 3x - 8 = 0
==> 5x^2 -8x +5x -8=0
==> x(5x-8) +1(5x-8)=0
==> (5x-8)(x+1) = 0

The earned run average (ERA) a of a baseball pitcher varies directly as the number of earned runs r and inversely as the number of pitched innings p. In one season, a pitcher has an ERA of 2.475 with 80 innings pitched and 22 earned runs. Find the number of earned runs if the pitcher has an ERA of 2.25 after pitching 112 innings in the next season.
Find the number of earned runs when the pitcher has an ERA of 2.25 after pitching 112 innings in the next season.
Answer:
The number of earned runs is 28.
Step-by-step explanation:
Earned runs average:
The earned runs average of a pitcher is the number of runs the he/she gives each 9 innings on average.
Find the number of earned runs when the pitcher has an ERA of 2.25 after pitching 112 innings in the next season.
Solved by proportions, using a rule of three.
For each 9 innits, the pitcher gives 2.25 runs. How many runs for 112 innings?
9 innings - 2.25 runs
112 innings - x runs
Applying cross multiplication:
[tex]9x = 2.25*112[/tex]
[tex]x = \frac{2.25*112}{9}[/tex]
[tex]x = 28[/tex]
The number of earned runs is 28.

Answer:
234
Step-by-step explanation:
From the given information :
The 4th term, a4
a1 = 3
a2 = 4(a1) + 2
a2 = 4(3) + 2 = 14
a3 = 4(a2) + 2
a3 = 4(14) + 2
a3 = 58
a4 = 4a3 + 2
a4 = 4(58) + 2
a4 = 232 + 2
a4 = 234
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Joseph sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 103 visitors purchased no costume. 161 visitors purchased exactly one costume. 7 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase more than one costume as a decimal to the nearest hundredth.
The probability that the next person will purchase more than one costume is 0.03
How to solve for the probabilityWe have the following details to solve the problem with
The people that did not purchase any costume = 103
Those that purchased exactly one costume = 161
Those that purchased more than one costume = 7
The total number of persons that we have here would be
103 + 161 + 7
= 271
We are to find the probability that the next would purchase more than 1 costume.
This is given as:
7 / 271 = 0.0258
To the nearest hundredth = 0.03
Hence, 0.03 is the probability that the next person is going to buy more than one costume.

Answer:
81%
Step-by-step explanation:
27 no costume, 112 exactly one costume, 3 more than one costume.
27+112+3=142
There were a toal of 142 customers. 112+3=115 visitors purchased one or more costumes costumes.
Probability the next visitor will purchase one or more costumes:
115/142=0.809859
0.809859 times 100% = 80.9859%
which rounds to 81%
The probability as a percent to the nearest whole number is 81%
One hexagonal prism has dimensions that are triple the dimensions of a similar hexagonal prism. If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
4.75 cm3
14.25 cm3
42.75 cm3
128.25 cm3
Answer:
128.25 cm³
Step-by-step explanation:
Volume of an hexagonal prism:
The volume of an hexagonal prism is given by:
[tex]V = \frac{3\sqrt{3} a^2h}{2}[/tex]
In which a and h are the dimensions.
Triple the dimensions
This means that the volume will be multiplied by 3^3, 27(as there are 3 terms which are dependent of the dimensions, a² and h).
If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
27*4.75 = 128.25 cm³
128.25 cm³ is the answer
Answer:

Ross has a plan to increase the number of sit-ups he does by the same percent each
week. The table shows his goal for each week of the plan.
Which expression gives the goal for the 52nd week?
Answer:
20•2^51
Step-by-step explanation:
The expression that gives the goal for the 52nd week is 20(2)⁵¹.
Week 1 2 3 4 5
Goals 20 40 80 160 320
This means the numbers are goals are increasing geometrically.
What is a geometric progression?A geometric progression is a series in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio.
We know the nth term of a GP = arⁿ⁻¹
Where a is the first term and r is the common ratio.
In our problem, a=20 and r=40/20=2
So, the 52nd term of the GP = 20(2)⁵²⁻¹
The 52nd term of the GP =20(2)⁵¹
Hence, the expression that gives the goal for the 52nd week is 20(2)⁵¹.

A number cube labeled 1 through 6 rolled three times. What is the probability that the first roll is a 1, the second roll is a 2, and the third roll is greater than 4?
Answer:
about 2/216 or 1/108
Step-by-step explanation:
the probability of it rolling 1 is 1/6. The probability of it rolling a 2 is 1/6. 1/6 times 1/6 is 1/36. the probability of it rolling a number greater than 4 is 2/6 since 5 and 6 are greater than 4. 1/36 times 2/6 is 2/216. Simplified is 1/108

To find how much she payed for every round she played (woah that rhymed) you multiply 6.25 by the amount of rounds she played, which is x.
That's where we get 6.25x
7.50 is the base cost, so she will pay that much regardless of how much she played.
26.25 is the total amount of money spent. The admition cost and how much she spent on playing ads up to her total cost

Given: Cone; Radius = 4 in, Height = 9 in.
To find: The volume of the specified cone
Formula: [tex]V=\frac{1}{3} h\pi r^2[/tex]
Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume multiply the base area (area of a circle: π × r²) by height and by [tex]\frac{1}{3}[/tex] : volume = ( [tex]\frac{1}{3}[/tex] ) × π × r² × h.
A heap of yam contain 40 tuber.if the average weight of each tuber is 5 3^4kg, what is the total weight of the heap?
Answer:
The total weight of the heap is 16,200 kilograms.
Step-by-step explanation:
Given that a heap of yam contain 40 tuber, to determine the total weight of the heap if the average weight of each tuber is 5 3 ^ 4kg, the following calculation must be performed:
(5x3 ^ 4) x 40 = X
(5x81) x 40 = X
405 x 40 = X
16,200 = X
Therefore, the total weight of the heap is 16,200 kilograms.

Andrew picks one marble at a time from a box and replaces it. He
repeats this process 25 times and records the results in the table. Based
on the table, which color marble has an experimental probability of 1/5?
4
Green
10
Answer:
Yellow.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Experimental probability is found taking into account previous experiments.
In this question:
6 + 5 + 4 + 10 = 25 total marbles.
The experimental probabilities are:
6/25 probability it is red.
5/25 = 1/5 probability it is yellow. Thus, the answer is yellow.
4/25 probability it is blue.
10/25 = 2/5 probability it is green.
