solve the following quadratic equation using the quadratic formula -2x^2-3x+4=0
Evaluate using order of operation and please show work
Answer:
10
Step-by-step explanation:
Given expression:
20 - [tex]\frac{15 + 3(5)^{2} }{5^{2} - 4^{2} }[/tex]
To solve this problem, we use the order of operation:
P - Parentheses
E - exponents
M - multiplication
D - division
A - Addition
S - Subtraction
Now solve the parentheses first;
= 20 - [tex]\frac{15 + 3x 25}{5^{2} - 4^{2} }[/tex]
= 20 - [tex]\frac{15 + 75}{5^{2} - 4^{2} }[/tex]
Now solve the exponents:
= 20 - [tex]\frac{15 + 75}{25 - 16}[/tex]
Now solve the division:
= 20 - [tex]\frac{90}{9}[/tex]
= 20 - 10
= 10

In which pair do both decimals represent rational numbers?
O A. 0.752 and 0.232323...
OB. 8.3182706837521... and 0.752
O C. 4.32891789376287184... and 0.2323
O D. 8.3182706837521... and 0.232323...
Answer:
A. 0.752 and 0.232323...
Step-by-step explanation:
A rational number is a number that can be expressed as a ratio. That is, it can be written as a quotient of two integers. A rational number can have a terminating decimal. E.g. 0.5, which can be expressed as ½ or 1:2. This is a terminating decimal. Also, a rational number could be a number that has repeating decimal that keeps repeating forever. E.g. 0.333... which can be expressed as ⅓, or 1:3.
An irrational number is just the opposite of a rational number. Thus, am irrational number cannot be expressed as ratio, and also has a decimal that goes on forever without repeating. For example, π = 22/7 = 3.14159... it has no definite ratio.
From these explanation we can easily pick out which pair that has both decimals representing rational numbers.
Thus, the answer is A. 0.752 and 0.232323...
0.752 is a terminating decimal, therefore it is a rational number.
0.232323... is a non-terminating decimal, however, its decimal is a repeating decimal. Therefore, it is a rational number.
Answer:
The answer is A 0.725 and 0.232323...

Use the number line below, where RS=9y+2, ST=2y+6, and RT= 52
Answer:
Step-by-step explanation:
Given
RS=9y+2, ST=2y+6, and RT= 52
The addition postulate is true for the number line.
RS+ST = RT
Substitute
9y+2+(2y+6) = 52
9y+2y+8 = 52
11y = 52-8
11y = 44
y = 44/11
y = 4
Find RS
RS = 9y+2
RS = 9(4)+2
RS = 36+2
RS = 38
Find ST:
ST = 2y+6
ST = 2(4)+6
ST = 8+6
ST = 14
Hence y = 4, RS = 38 and ST = 14

-t+5=t-19
Need an answer and a work pls!
Answer:
t=12
Step-by-step explanation:
Step 1: Subtract t from both sides.
−t+5−t=t−19−t
−2t+5=−19
Step 2: Subtract 5 from both sides.
−2t+5−5=−19−5
−2t=−24
Step 3: Divide both sides by -2.
−2t−2=−24−2

The science teacher gives daily homework. For a random sample of days throughout the year, the median number of problems is 5 and the IQR is 2. The Spanish teacher also gives daily homework. For a random sample of days throughout the year, the median number of problems is 10 and the IQR is 1. If you estimate the median number of science homework problems to be 5 and the median number of Spanish problems to be 10, which is more likely to be accurate? Explain your reasoning.
Answer:
SCIENCE SEEMS MORE ACCURATE
Step-by-step explanation:
The interquartile range (IQR) = difference between the upper and lower quartile (Q3 - Q1)
The median can be estimated as :
(Q3 - IQR/2) or (Q1 + IQR/2).
FOR SCIENCE:
MEDIAN NUMBER = 5
IQR = 2
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 5 + 2/2 = 6
Q1 = median - IQR/2 = 5 - 2/2 = 4
FOR SPANISH:
MEDIAN = 10
IQR = 1
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 10 + 1/2 = 10.5
Q1 = median - IQR/2 = 10 - 1/2 = 9.5
Science has a lower median score and an interquartile range which is reasonable wider than Spanish with a larger median value (but a very narrow interquartile range).
Simon bought three plants at a nursery for 17.94 how hutch money would it cost for Simon to go back to the store and buy two more plants. Please help me !
Answer:
11-96
Step-by-step explanation:
The money required for Simon to buy two more plants is 11.96
What is Average?
The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Given data ,
Number of plants Simon bought = 3 plants
Total amount of plants = 17.94
Amount for one plant = Total amount of plants / Number of plants bought
So , Amount for one plant = 17.94 / 3
= 5.98
Therefore , Amount of cost for Simon to buy two more plants = Amount of one plant x 5.98
= 5.98 x 2
= 11.96
Hence , The money required for Simon to buy two more plants is 11.96

Listed below are the 35 members of the Metro Toledo Automobile Dealers Association. We would like to estimate the mean revenue from dealer service departments. The members are identified by numbering them 00 through 34.
Answer:
Metro Toledo Automobile Dealers Association
a) The mean revenue
= Total Revenue from the dealer service departments/35
b) The sample of five include 27, 23, 32, 11, and 13
c) Using systematic random sampling, the dealers included in the sample are: 7, 13, 19, 25, and 31.
Step-by-step explanation:
a) The mean value is the total value divided by the number of elements. The mean revenue is, therefore, the total revenue from the dealer service departments divided by the number of dealers. This gives an average revenue from each dealer, which is a statistic to describe the population.
b) The sample of five cannot include any number that is outside the population. For example, 85 is not a number allocated to any dealer in the indicated population, therefore, it cannot form part of the population sample.
c) The systematic random sampling starts from 7 and chooses the sixth number after 7. Therefore, the next four numbers are multiples of 6. This is why we choose 13, 19, 25, and 31.
