Could someone PLEASE help me!

Answer:

f = -5

Step-by-step explanation:

If 2x – 1 is a factor of 16x4 + 24x3 + 2x + f, find f.

If 2x - 1 = 16x⁴ + 24x³ + 2x + f, find f.

2x - 1 = 0

2x = 1

x = 1/2

Hence

f(1/2) = 16(1/2)⁴ + 24(1/2)³ + 2(1/2) + f

= 16(1/16) + 24(1/8) + 1 + f

= 1 + 3 + 1 + f

= 5+ f

f = -5

The total length of the trip 190.08 miles

How you do it is to add the 44% of 132 to 132

= (132 + (132×44%))

Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived.

First, you have to find out how much 44% is. Change it into decimal form (0.44) and then multiply the two together.

132 × 0.44 is 58.08 miles.

Then you add that to the rest of the trip, 132 miles.

= (132 + 58/08

=190.08

The total length of the trip was 190.08 miles.

Answer: 2,916 inches³

Step-by-step explanation:

The volume of a box is:

= Length * Width * Height

But all of these have to have the same units for it to work. This means that the height of the box will have to be converted to inches :

1 ft is 12 inches so:

= 1¹/₂ * 12

= 3/2 * 12

= 18 inches

Volume is therefore:

= 18 * 9 * 18

= 2,916 inches³

The required ratio WJ/WK is 3, which is determined by using the concept of dividing a line segment.

Let U and V be the two other distinct points on the line such that UJ/UK = 4 and VJ/VK = 7.

We have to find the ratio WJ/WK, where W is the midpoint of UV.

Let the distance between J and K be x. Then, we have:

Since W is the midpoint of UV, we have:

WJ = (UJ + VJ)/2 = (4x/5 + 7x/8)/2 = 39x/80

WK = (UK + VK)/2 = (x/5 + x/8)/2 = 13x/40

Therefore, the ratio WJ/WK is:

WJ/WK = (39x/80)/(13x/40)

= 3

Answer:

A) The algebraic expression

= 12x + 7 = 91

B) He drives 7 miles per day

Step-by-step explanation:

For 11 days straight, Mike drove the same distance every day going to and coming from work.

Step 1

We are told : Mike drives 91 miles in total in those 12 days,

On the 12th day, he drove an extra 7 miles.

Hence:

91 miles - 7 extra miles

= 84 miles

Step 2

The number of miles he drives per day:

84 miles/12

= 7 miles per day

Step 3

The expression we can use to find the distance he travels each day going to and from work is written as:

Let the number of miles he travels be day = x

12x + 7 = 91 miles

12x + 7 = 91

12x = 91 - 7

12x = 84

x = 84/12

x = 7 miles per day

Parallelogram

It's a quadrilateral formed by two pairs of parallel sides. The opposite sides have equal lengths.

We are given a parallelogram with opposite sides of 3x+1 and 6x-4. They must be equal, thus:

6x - 4 = 3x + 1

Subtracting 3x:

3x - 4 = 1

Adding 4:

3x = 5

Dividing by 3:

The simplified form of the trigonometric expression csc2(x) − 1 csc2(x) is: cos2(x)/sin2(x)

The simplification of the trigonometric expression csc2(x) − 1 csc2(x) requires a bit of algebraic manipulation.

We can start by using the identity csc2(x) = 1/sin2(x) to rewrite the expression as:
1/sin2(x) − 1 / (sin2(x) * csc2(x))

Next, we can simplify the denominator of the second term using the identity csc2(x) = 1/sin2(x), giving us:
1/sin2(x) − 1 / (sin2(x) * (1/sin2(x)))

Simplifying further, we get:
1/sin2(x) − 1/sin2(x)

Finally, we can combine the two terms with a common denominator to get:
(1 - sin2(x))/sin2(x)

This expression can be further simplified using the identity sin2(x) + cos2(x) = 1, which gives us:
cos2(x)/sin2(x)

Therefore, the simplified form of the trigonometric expression csc2(x) − 1 csc2(x) is: cos2(x)/sin2(x)

Answer:

3/4

Step-by-step explanation:

the chance of getting a head is 1/2 or a tail is 1/2 in the first turn.

and the chance of getting a head is 1/2 or a tail is also 1/2 in the 2nd turn as well.

the possibilities are HH, TH, HT, TT

only three of these possibilities have at least one head (HH, TH, HT)

the possibility of scoring double heads is 1/4 (1/2 * 1/2)

the possibility of scoring a tail and head is 1/4 ( 1/2 * 1/2)

the possibility of scoring a head and then tail is also 1/4 (1/2 * 1/2)

adding all the possibilities (1/4 + 1/4 + 1/4) is 3/4  

The number of ways to order the first, second and third place finishers is simply the number of permutations of 8 runners taken 3 at a time. This can be calculated using the formula for permutations

The formula for permutations, P(n,r), gives the number of ways to choose r items from a set of n items, where order matters. This formula is calculated as:

P(n,r) = n! / (n-r)!

where n! represents the factorial of n (i.e. n multiplied by n-1 multiplied by n-2, etc. down to 1).

In this problem, n = 8 and r = 3, so the number of permutations is:

P(8,3) = 8! / (8-3)! = 8! / 5! = 40320 / 120 = 336

So there are 336 different arrangements of first, second, and third place finishers in the 100-meter sprint.

The 95% confidence interval based on this sample is =

[6.41, 7.79]

Step-by-step explanation:

The formula for Confidence Interval =

Mean ± z × standard deviation/√n

Sample mean = 7.1 hours

Standard deviation = 5 hours

n = 200 students

z = 95% confidence interval z score

= 1.96

C.I = 7.1 ± 1.96 × 5/√200

C.I = 7.1 ± 0.693

Hence, Confidence Interval

= 7.1 - 0.693

= 6.407

Approximately = 6.41

= 7.1 + 0.693

= 7.793

Approximately = 7.79

Therefore, the 95% confidence interval based on this sample is

The three conditions for hypothesis testing are approximately met, and the null hypothesis is that the population mean daily high temperature in Buenos Aires is 18.2∘C.

The three conditions for hypothesis testing are approximately met based on the information given.

Null hypothesis (H0) is that the population mean daily high temperature in Buenos Aires is 18.2∘C. Alternative hypothesis (Ha) is that the population mean daily high temperature in Buenos Aires is greater.

The test statistic is calculated as (sample mean - population mean) / (sample standard deviation / sqrt(sample size)).

The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed test statistic, assuming the null hypothesis is true. It can be calculated using a t-distribution with degrees of freedom equal to the sample size minus one.

Arnav needs to sell more than 8 boxes of cookies to reach his goal of making more than $30. Since the number of boxes must be a whole number, Arnav would need to sell at least 9 boxes of cookies to achieve his goal.

To determine how many boxes of cookies Arnav needs to sell to reach his goal of making more than $30, we can set up an inequality based on the selling price of each box.

Let's represent the number of boxes he sells as "x". Since each box is sold for $3.75, the total amount of money he will earn from selling "x" boxes is 3.75x.

To reach his goal of making more than $30, we can write the following inequality:

3.75x > 30

To solve for "x", we divide both sides of the inequality by 3.75:

x > 30 / 3.75

Simplifying the right side of the inequality, we get:

x > 8

To fulfil his objective of earning more than $30, Arnav must sell more than 8 boxes of cookies. Arnav would need to sell at least 9 boxes of cookies in order to reach his objective because the number of boxes must be a whole number.
