D. [tex]3m^2+m-5[/tex]

Step-by-step explanation:

A trinomial expression is a polynomial expression with three terms.

The term with the highest power of variable is called the leading term and the co-efficient of this term is called the leading co-efficient.

The alone number without any variable in the expression is called the constant.

Example of a trinomial:

[tex]5x^2+2x+4[/tex]

Leading co-efficient = 5

Constant = 4

A trinomial with a leading coefficient of 3 and a constant term of -5 from the given choices is:

D. [tex]3m^2+m-5[/tex]

Using combinations in mathematics, it's found that there are 4 different 3-topping pizzas possible from a selection of 4 toppings, since the order of toppings on a pizza does not matter.

Combination Calculation for Pizza Toppings

When considering the number of different 3-topping pizzas possible from 4 choices, one must use combinations to solve this problem. A combination is a selection of items where the order does not matter, which fits our scenario since the order of toppings on a pizza does not change the pizza's identity. In mathematical terms, we look for the number of combinations of 4 items taken 3 at a time, which is denoted as 4C3.

The formula for combinations is:

C(n, k) = n! / (k!(n-k)!), where n is the total number of items, k is the number of items to choose, and ! denotes a factorial.

Thus, for our pizza topping problem, this becomes:

4C3 = 4! / (3!(4-3)!) = (4×3×2×1) / ((3×2×1)×1) = 24 / 6 = 4 different 3-topping pizzas.

Therefore, there are 4 different ways to select 3 toppings from a choice of 4.

Answer:

Part A: Option C

Part B: Option B

Step-by-step explanation:

Part A:  

We have to find the equation of a straight line having x-intercept at (3,0) and y-intercept at (0,2).

Now, using intercept form of straight line equation we can write the equation of the required straight line is [tex]\frac{x}{3} + \frac{y}{2} = 1[/tex]

⇒ [tex]\frac{y}{2} = 1 - \frac{x}{3}[/tex]

⇒ [tex]y = - \frac{2}{3} x + 2[/tex]  

So, option C is correct. (Answer)

Part B:  

See the graph of the straight line provided.

The straight line passes through the points (10, 80) and (20, 100)

Therefore, the slope of the straight line is given by [tex]\frac{100 - 80}{20 - 10} = \frac{20}{10} = 2[/tex]

therefore, option B is correct. (Answer)

Answer:

The two cars are at the distance of 21 miles apart .

Step-by-step explanation:

Given as :

The car travel due north to the distance  = 12 miles

The car travel due south to the distance = 9.12 miles

let the distance between the two cars = x miles

So, the total distance between the cars = The distance of north going car + the distance of south going car

Or,  the total distance between the cars = 12 miles + 9.12 miles

or,  the total distance between the cars =  21.12 miles ≈ 21 miles

I.e the total distance between the cars = 21 miles

Hence The two cars are at the distance of 21 miles apart . Answer

Answer:

24 : 8 ≡ 39 : 13

Step-by-step explanation:

We are given two proportion relation and we have to determine whether they are equivalent or not.

Now, the first proportion is 24 : 8

So, the simplified proportion will be 24 : 8 = 8 × 3 : 8 = 3 : 1

Again the second proportion is 39 : 13

So, the simplified proportion is 39 : 13 = 13 × 3 : 13 = 3 : 1

Therefore, the two given proportions are equivalent i.e. 24 : 8 ≡ 39 : 13. (Answer)

Answer:

[tex]x=16[/tex]

 Lenght of the equal sides: [tex]71\ units[/tex]

Step-by-step explanation:

You can observe in the picture that the triangle have two angles that have equal measure; therefore, it is an Isosceles triangle.

By definition, Isosceles triangles have two equal angles and two equal sides.

Based on this, you can write the following equation:

[tex]9x-73=3x+23[/tex]

Solving for "x", you get this value:

[tex]9x-3x=23+73\\\\6x=96\\\\x=\frac{96}{6}\\\\x=16[/tex]

Finally, you can subsitute the value of "x" into any expression to find the lenght of the equal sides:

[tex]3(16)+23=71\ units[/tex]

You first add 92+20. You will get 112. So 112 seashells collected.

Answer:

The radioactive substance will decay in 17.70 hours .

Step-by-step explanation:

Given as :

The rate of decay of radioactive substance = 4 %  per hour

Let The original weight of substance = w

The final weight of substance = [tex]\frac{w}{2}[/tex]

Let the hours for decay of substance = n

Now,

The weight of substance after n years = The original weight of substance × [tex](1- \dfrac{\textrm Rate}{100})^{n}[/tex]

or,

[tex]\frac{w}{2}[/tex] = w × [tex](1- \dfrac{\textrm 4}{100})^{n}[/tex]

Or, [tex]\frac{1}{2}[/tex] = [tex](1- \dfrac{\textrm 1}{25})^{n}[/tex]

or,  [tex]\frac{1}{2}[/tex] = [tex](\dfrac{\textrm 25-1}{25})^{n}[/tex]

or,  [tex]\frac{1}{2}[/tex] = [tex](\dfrac{\textrm 24}{25})^{n}[/tex]

Taking log both sides :

Log  [tex]\frac{1}{2}[/tex] = Log [tex](\dfrac{\textrm 24}{25})^{n}[/tex]

So, Log [tex]\frac{1}{2}[/tex] = n × Log [tex]\frac{24}{25}[/tex]

∴ - 0.301 =  n × ( - 0.017 )

So , n = [tex]\frac{0.301}{0.017}[/tex]

I.e n = 17.70  hours

Hence The radioactive substance will decay in 17.70 hours . Answer

Answer:

0.22 hours

Step-by-step explanation:

Half life is defined as the time taken by a radioactive material to decay to half of its original value.

Mathematically, half-life (t1/2) = ln2/¶ where ¶ is the decay constant.

Before we can get the half life, we need to get the decay constant first. To get ¶, we will use the radioactivity formula. According to the formula,

N/No = e^-¶t where;

N/No is the fraction of the final substance after decay the the original value of the substance = 4% = 1/25

t is the time of decay = 1hour

Substituting into the formula to get the decay constant we have;

1/25 = e^-1¶

Applying ln to both sides, we have;

ln 1/25 = lne^-¶

ln1/25 = -¶

-3.22= -¶

¶ = 3.22

The decay constant is 3.22

Half life = ln2/3.22

Half life = 0.22hours

It will take the substance 0.22hours before it changes to half of its original weight.

Answer:

First Side  = 21 units

Second side = 21 units

Third side  = 21 units

Step-by-step explanation:

Here, the three sides of the equilateral triangle are:

(2 x-7) cm , ( x + y - 9) cm and ( y + 5) cm

Now, a triangle is said to be an EQUILATERAL TRIANGLE if all three sides of the triangles are equal in the measure.

⇒ For the given triangle to be equilateral:

(2 x-7)   =  ( x + y - 9)  =  ( y + 5)

Consider third and second term, we get:

x + y -9  = y + 5

or, x - 9  = 5  

⇒  x = 9 + 5  = 12, or x = 14

Also,from first and second   term :

(2 x-7)  =  ( x + y - 9)  

⇒ 2(14) - 7 =  (14 + y) - 9

⇒ 28  - 7 -14 + 9 = y

or, y = 16

Hence, First Side =  2 x - 7 = 2(14) - 7 = 21 units

Second side = x + y - 9 = 14+ 16  - 9 = 21 units

Third side =  y + 5 = 16 + 5 = 21 units

Answer:

 The percent change is 400%

Explanation:

We know that percentage change is given by the

[tex]\frac{change in value}{absolute value of the original value} \times 100[/tex]

i.e we find the difference between the original value and current value and then divide it by original value and multiply the obtained value with 100.

a negative percentage change indicates increase in value.

so we get 4 - 20 = -16

[tex]\frac{-16}{4}[/tex] = -4

[tex]-4 \times[/tex] 100 = -400

hence there is an increase of 400% in the percentage which is the required percentage.

Answer:

66.67%

Step-by-step explanation:

Marie's earnings at a new job : $15 per hour

Her earnings during training : $10 per hour

percentage of Marie's regular rate earned by her during training

                 = [tex]\frac{Her\ earnings\ during\ training}{Her earning\ at\ a\ new\ job}[/tex]×100

                 = [tex]\frac{10}{15}[/tex]×100

                 = [tex]\frac{200}{3}[/tex]

                 = 66.67%

∴percentage of Marie's regular rate earned by her during training = 66.67%

Final answer:

To find what percentage of Marie's regular rate she will earn during training, divide her training rate by her regular rate and multiply by 100%.

Explanation:

Marie will earn $10 per hour during training. Her regular rate is $15 per hour. To calculate what percentage of her regular rate she will earn during training, we use the formula: percentage = (training rate / regular rate) * 100%. Plugging in the values, we get (10 / 15) * 100% = 66.67%. Therefore, Marie will earn 66.67% of her regular rate during training.

Answer:

(17.42 ; 22.38)

Step-by-step explanation:

To construct a confidence interval we use the following formula:

ci = (sample mean) +- z*(sd)/[n^(1/2)]

The sample mean is 19.9 and the standard deviation is 6. The sample has a n of 16. We have to find the value of z which is the upper (1-C)/2 critical value for the standard normal distribution. Here, as we want a confidence interval at a 90% we have (1-C)/2=0.05 we have to look at the 1-0.05=0.95 value at the normal distribution table, which is 1.65 approximately. Replacing all these values:

ci: (sample mean - z*(sd)/[n^(1/2)] ; sample mean + z*(sd)/[n^(1/2)])

ci: (19.9 - 1.65*6/[16^(1/2)] ; 19.9 + 1.65*6/[16^(1/2)])

ci: (19.9 - 9.9/4] ; 19.9 + 9.9/4)

ci: (19.9 - 2.48 ; 19.9 + 2.48)

ci: (17.42 ; 22.38)

To find a 90% confidence interval for the mean time, we can use the formula C-I = x ± z * (σ/√n). Using the given sample mean, sample standard deviation, and sample size, the 90% confidence interval is approximately (17.43, 22.37) minutes.

To find a 90% confidence interval for the mean time, we can use the formula:

C-I = x ± z * (σ/√n)

Where:

Since the population standard deviation is unknown, we can use the sample standard deviation as an estimate. The z-score corresponding to a 90% confidence level is approximately 1.645.

Plugging in the given values:

C-I = 19.9 ± 1.645 * (6/√16)

C-I = 19.9 ± 1.645 * 1.5

C-I = 19.9 ± 2.46875

Therefore, the 90% confidence interval for the mean time is approximately (17.43, 22.37) minutes.
