Answer:

\(\huge\boxed{\sf 63}\)

Step-by-step explanation:

\(= x^2+10x + 24\)

Put x = 3

= (3)² + 10(3) + 24

= 9 + 30 + 24

= 63

\(\rule[225]{225}{2}\)

Answer:

Option D) 63 is the correct answer.

Step-by-step explanation:

where :

\( \quad\sf{\dashrightarrow{{x}^{2} + 10x + 24}}\)

Substituting the value of x :

\( \quad\sf{\dashrightarrow{{(3)}^{2} + 10 \times 3 + 24}}\)

\( \quad\sf{\dashrightarrow{(3 \times 3) + 30 + 24}}\)

\( \quad\sf{\dashrightarrow{(9) + 54}}\)

\( \quad\sf{\dashrightarrow{9 + 54}}\)

\( \quad\sf{\dashrightarrow{63}}\)

\(\quad{\star{\underline{\boxed{\sf{\pink{63}}}}}}\)

Hence, the answer is 63.

Step-by-step explanation:

2(10x+2)=64

20x+4=64

20x=60

x=60÷20

x=3

Answer:

x=3

Step-by-step explanation:

2

(10x+2)=64

=

20x+4=64

Subtract 4 from both sides

20x=60

Divide both sides by 20

20x/20 = 60/20

therefore x = 3

Step-by-step explanation:

The effect of treatments on blood potassium levels in freshwater mussels was evaluated using appropriate statistical analysis (e.g., ANOVA or Kruskal-Wallis test) on the data collected from three randomly assigned groups, allowing for the determination of significant differences among treatment groups.

Conduct the statistical analysis: Perform the chosen statistical test using the collected data. The analysis will calculate a test statistic and associated p-value, which quantifies the strength of evidence against the null hypothesis.

Determine the significance level: Set a significance level (e.g., α = 0.05) to determine the threshold for statistical significance. This represents the level of evidence required to reject the null hypothesis.

Evaluate the results: Compare the obtained p-value to the significance level. If the p-value is less than the chosen significance level, there is sufficient evidence to reject the null hypothesis and conclude that the treatments have an effect on blood potassium levels in freshwater mussels. Conversely, if the p-value is greater than the significance level, there is insufficient evidence to reject the null hypothesis, and it cannot be concluded that the treatments have an effect on blood potassium levels.

There are 28 ways to choose 6 teams for the playoffs if there are 8 college basketball teams in a certain sub-division.

To determine the number of ways to choose 6 teams for the playoffs out of the 8 college basketball teams in a certain Sub-Division, we can use the combination formula. The formula for combinations is given by

nCr = n! / (r! * (n-r)!),

where n represents the total number of teams and r represents the number of teams to be chosen.

In this case, n = 8 and r = 6.

Plugging in these values, we have

8C6 = 8! / (6! * (8-6)!) = 8! / (6! * 2!) = (8 * 7) / (2 * 1) = 28.

Therefore, there are total 28 ways to choose 6 teams.

Based on z-scores, the answer is No, the data for offices without a wait-tracking system does not contain any outliers.

A Z-score is a statistical measure that tells how far away an observation is from the mean in terms of standard deviations. It represents how many standard deviations the value of an observation is from the average value (mean).

It is possible to identify whether a value in a data set is an outlier by looking at its Z-score. When a value's Z-score is larger than 3 or smaller than -3, it is considered an outlier. For z-scores ranging between -3 and 3, it is considered an acceptable range.

As a result, the answer is no, based on the z-scores, the data for offices without a wait-tracking system does not contain any outliers.

If P(first not defective) = 3910/4000 and it is not changed (1 less to choose from and 1 less not defective)

P(second is not flawed if first is flawed) = 3909/3999 If the item is also not replaced (a total of 2 less to choose from and 2 less not defective)

P

(1st and 2nd are not defective, so the third is also not defective)) = 3908/3998

To find the area of ΔABC, we can use the formula for the area of a triangle:

Area = (1/2) * base * height

In this case, we have the length of side a (9.71) and side c (9.33), and we know the measure of angle A (52°). To find the height, we can use the sine function.

First, find the length of side b using the Law of Cosines:
b^2 = a^2 + c^2 - 2 * a * c * cos(A)
b^2 = 9.71^2 + 9.33^2 - 2 * 9.71 * 9.33 * cos(52°)
b^2 ≈ 94.244

Now, find the height (h) using the sine function:
sin(A) = h / b
h = b * sin(A)
h ≈ 6.966

Finally, calculate the area of the triangle:
Area = (1/2) * a * h
Area = (1/2) * 9.71 * 6.966
Area ≈ 33.786

Rounding to the nearest tenth, the area of ΔABC is approximately 33.8 square units.

iii) Point D is located at 35.

iv) -20 is one tick mark to the left of point A.

Explanation:

A function has each x value map to exactly one y value. Choice A demonstrates this, which is why it's a function. Note how none of the x values are repeated in this table.

Choices B, C and D have repeated x values, which in turn means that we have an x input lead to multiple y outputs. For instance, choice B says that the input x = -5 has the two outputs y = -5 and y = 5; this is sufficient to show that table B is not a function. Choices C and D are a similar story.

17 13/24 cups of sugar

Step-by-step explanation:

Muffins = 5 3/8 cups of sugar

Brownies = 4 2/3 cups of sugar

Cookies = 7 1/2 cups of sugar

Total cups of sugar used = Muffins + Brownies + Cookies

= 5 3/8 + 4 2/3 + 7 1/2

= 43/8 + 14/3 + 15/2

= 129+112+180/24

= 421 / 24

= 17 13/24 cups of sugar

Equivalent to 17.5417 cups of sugar

Approximately about 18 cups of sugar to an whole number

The car travelled at 80km/h for 7 hours and travelled a distance of 560km whereas the ferry travelled at 16km/h for 20 hours and travelled a distance of 320km.

We know that the Anderson’s travelled for 880 km from St. Johns to Halifax via Argentia and that part of the trip was by car at 80 km/h and the rest by ferry at 16 km/h.

we need to find how much time did it take the Anderson’s to travel by car and by ferry

as part of the journey was done by car and the other by ferry

560km was travelled by car therefore now we need to find time travelled by car = distance = speed x time

we get time travelled by car = 7 hours

similarly we need to find the time take by ferry we have:

320km travelled by ferry at 16km/h we get the time travelled by ferry = 20hours

The Answer is

7 - 2x

Step-by-step explanation:

23 -14x + 12x - 16

(23 - 16) + (-14x + 12x)

= 7 - 2x

hope this help a'lot

The expression equivalent to 23−14x+12x−16 is 7 - 2x

Here we simply take our expression to simplify it.

We start with:

23−14x+12x−16

First, we combine all the terms having x and combine other constant values.

(23 - 16) + (-14x + 12x)

Now we solve the two parts of the above expression we will get,

7 + (- 2x)

Simplifying we get,

7 - 2x

Therefore  the equivalent expression is 7 - 2x

Answer:

-12a + 15b

Step-by-step explanation:

-3(4a - 5b)

Multiply -3 with both 4a and 5b,

-3(4a) + -3(-5b)

= -12a + 15b

In order to simplify this expression, we need to use the Distributive property, which states the following:-

\(\bigstar{\boxed{\pmb{a(b+c)=ab+ac}}}\)

Distribute:-

\(\sf{-3(4a-5b)}\)

Multiply -3 times the terms inside the parentheses:-
