Calculate the probability of randomly selecting a vehicle with an engine size greater than 3. 9 L.
The probability we consider factors that decide what engine is chosen and the odds of choosing an engine size greater than 3.9 L
Probability of choosing an engine sizeAn engine size greater than 3.9 L
Generally, This can be defined as the possibility of an event occurring with respect to other possible outcomes.
Probability looks at calculating the possibility of a given event's occurrence.
To determine the possibility of selecting an engine size greater than 3.9 L, we consider factors than decide what engine is chosen and the odds of choosing an engine size greater than 3.9 L
Hence, the probability we consider factors that decide what engine is chosen and the odds of choosing an engine size greater than 3.9 L

Expand the function then solve;
[tex]\rm f(x)=-(x +8)(x-14)\\\\f(x)=-(x(x-14)+8(x-14))\\\\f(x)=-(x^2-14x+8x-112)\\\\f(x)= -x^2+6x+112[/tex]

Triangle ABC has perimeter 22 cm.
AB = 8 cm
BC = 5 cm
By calculation, deduce whether triangle ABC is a right-angled triangle.
Answer:
No, its not a right angle triangle. check for explanation below ↓
In order to figure whether ABC is a right-angled triangle.
First find the missing side:
22 - 8 - 5
9 cm
so the sides are 5 cm, 8 cm, 9 cm
using the rule:
short side² + short side² = biggest side²
5² + 8² = 9²
25 + 64 = 81
89 = 81
Thus found ABC is not a right-angled triangle.
[tex]AC = 22 - (8+5) = 22 - 13 = 9[/tex]
[tex]9^2 + 13^2 = 81 +169 = 250[/tex]
[tex]22^2 = 484[/tex]
So no, ABC is NOT a right triangle because the pythagorean thoerem fails
A school held a special math event for parents. On the first night, 150 parents attended, which was 40% below the expected attendance. On the second night, 210 parents attended, exceeding the expected attendance by 40% . By what percent did the actual attendance at the special math event exceed or fall below the expected attendance for both nights?
Answer:
10.429% exceed
Step-by-step explanation:
expected:
150x [100+40]/100=210 parents were expected on first night
210x60/100=126 parents expected on the second night
210+126=326 expected
percentage difference=
210+150=360
360/326 x 100=110,429%
110,429%-100%=10,429% exceed

A superhero has been called to rescue the planet from destruction. He leaves from a point on the equator and flies along the equator at 60,000 m/min. At the same time his partner flies from thee same location in the opposite direction at 4415 km/h. Please explain why
The superhero moves at 3600 km/h and his partner at 4415 km/h. The earth is round, so both him and his partner can get to the same location even travelling at opposite directions.
What is speed?Speed is the ratio of distance travelled to the total time taken, it is given by:
Speed = distance / time
The superhero flies at 60000 m/min = (60000m * 1 km per 1000 m) / (1 min * 1 hr per 60 min) = 3600 km/h
The earth is round, so both him and his partner can get to the same location even travelling at opposite directions.

A 5-year loan with a 4.2% annual simple interest rate
A 6-year loan with a 4.7% annual simple interest rate
O
A 3-year loan with an 8.4% annual simple interest rate
Answer:
number one is the best one
The loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.
Calculation of loan with least simple interest rateFormula for simple interest = P ×T × R/100
P = Principal amount borrowed ($12,000)
T = Time in various years given
R = Rate of simple interest generated
To determine which loan option that would allow the customer to pay the least amount of interest, the simple interest of each option is calculated below
Simple interest of a 4 years loan = 12000×4×5.2/100
= $2,496
Simple interest of a 5 years loan= 12000×5×4.2/100
= $2,520
Simple interest of a 6 years loan= 12000×6×4.7/100
= $3,384
Simple interest of a 5 years loan= 12000×3×8.4/100
= $ 18,144
Therefore, the loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.

An environmental group conducted a study to determine whether crows in a certain region were ingesting food containing unhealthy levels of lead. A biologist classified lead levels greater than 6.0 parts per million (ppm) as unhealthy. The lead levels of a random sample of 23 crows in the region were measured and recorded. The mean lead level of the 23 crows in the sample was 4.90 ppm and the standard deviation was 1.12 ppm.
a) Construct and interpret a 90 percent confidence interval for the mean lead level of crows in the region.
b) A previous study of crows showed that the population standard deviation was at 2.6 ppm. What minimum sample size would be required to construct a 90 percent confidence interval to have a margin of error within 0.03?
Part A
Given info:
xbar = sample mean = 4.90 ppms = sample standard deviation = 1.12 ppmn = 23 = sample sizeBecause n > 30 is not true, and we don't know the population standard deviation (sigma), this means we must use a T distribution.
The degrees of freedom here are n-1 = 23-1 = 22.
At 90% confidence and the degrees of freedom mentioned, the t critical value is roughly t = 1.717
Use a T distribution table or calculator to determine this. If you don't have a calculator for the task, then you can search out "inverse T calculator" and there are tons of free options to pick from.
The margin of error E is
E = t*s/sqrt(n)
E = 1.717*1.12/sqrt(23)
E = 0.400982
This is approximate and accurate to 6 decimal places.
The confidence interval is going to be xbar plus or minus that E value
L = lower bound = xbar - E = 4.90 - 0.400982 = 4.499018 = 4.50
U = upper bound = xbar + E = 4.90 + 0.400982 = 5.300982 = 5.30
The confidence interval in the format of (L, U) is (4.50, 5.30)
You could also express it as the format L < mu < U and it would be 4.50 < mu < 5.30; however, I'll stick to the first method.
Answer: (4.50, 5.30)=====================================================
Part B
Since we know sigma = 2.6 is the population standard deviation, we can use a Z distribution now.
At 90% confidence, the z critical value is roughly 1.645; use a table or calculator to determine this.
[tex]n = \left(\frac{z*\sigma}{E}\right)^2\\\\n \approx \left(\frac{1.645*2.6}{0.03}\right)^2\\\\n \approx 20325.254444 \\\\[/tex]

The sum of 8 terms of an A.P. is 12, and the sum of 16 terms is 56.

Step-by-step explanation:
[tex]S_{n}=\dfrac{n}{2}(2a + (n-1)*d)[/tex]
Here, n- number of terms ; d - common difference ; a - first term
[tex]S_{8}=12\\\\\dfrac{8}{2}[2a+(8-1)*d]=12\\\\4[2a+7d]=12\\\\2a + 7d = \dfrac{12}{4}\\\\\\2a + 7d = 3 \ -----------------------(i)[/tex]
[tex]S_{16}=56\\\\\dfrac{16}{2}(2a+15d)=56\\\\\\8(2a+15d)=56\\\\2a + 15d=\dfrac{56}{8}\\\\\\[/tex]
2a + 15d = 7 ----------------(ii)
Subtract (i) from equation (ii)
(ii) 2a + 15d = 7
(i) 2a + 7d = 3
- - -
8d = 4
d = 4/8
d = 1/2
Plugin d = 1/2 in equation (i)
[tex]2a +7*\dfrac{1}{2}=3\\\\\\2a = 3 -\dfrac{7}{2}\\\\\\2a =\dfrac{6}{2}-\dfrac{7}{2}\\\\\\2a=\dfrac{-1}{2}\\\\\\a=\dfrac{-1}{2*2}\\\\\\a=\dfrac{-1}{4}[/tex]
Second term = first term + d
