Answer:

c ≥ $13

Step-by-step explanation:

We know that Linda will spend more than $29 on a gift.

This means that if S is the total amount she will spend on the gift, the minimum that she can spend is $29, we can write this as:

S is larger than or equal to $29

S ≥ $29

Now we know that she already spent $16, then we can write:

S = $16 + c

Where c is the additional amount she will spend.

Replacing that in our inequality we get

$16 + c ≥ $29

Now we can subtract $16 in both sides to get:

$16 + c - $16 ≥ $29 - $16

c ≥ $29 - $16 = $13

c ≥ $13

This means that she will spend at least another $13,

Answer:

There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes

Step-by-step explanation:

H0 : μ = 3.8

H1 : μ < 3.8

Test statistic :

(x - μ) ÷ s/sqrt(n)

(3.7 - 3.8) ÷ 0.6/sqrt(60)

Test statistic = - 1.29

The Pvalue from test statistic :

P(z < -1.29) = 0.0985

Reject Null if

Pvalue < α

0.0986 > 0.01 ; Hence, we fail to reject the null ;

There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes

Answer:

11.2 Slices / Week

Step-by-step explanation:

We know that Jake has eaten 5 slices of cake in 3 days. You can divide 5 / 3 to get an average of 1.6 slices of cake being eaten per day. The question asks what the weekly rate or eating the cake will be, do you need to multiple 1.6 x 7 for the total amount of cake eaten per week, which is 11.2 slices!

Answer: 10 m/s

Step-by-step explanation:

Given

Momentum of boy [tex]P=200\ kg.m/s[/tex]

Mass of boy is [tex]m=20\ kg[/tex]

Momentum is the product of mass and velocity

[tex]P=mv[/tex]

Substitute value

[tex]\Rightarrow 200=20\times v\\\Rightarrow v=10\ m/s[/tex]

The frequency of an event uses counting numbers, but the ___Relative Frequency__ of an event uses a percent or a number between 0 and 1.

Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).

It ranges from 0 to 1 (since sub group's count ≤ total count. Expressing this decimal form to percent make it range from 0% to 100%

Thus, the frequency of an event uses counting numbers, but the ___Relative Frequency__ of an event uses a percent or a number between 0 and 1.

Answer:

Length of the pool = 52 m

Width of the pool = 25 m

Step-by-step explanation:

Perimeter of rectangular pool = 154 m

Let the length of rectangular pool = l m

And width of the rectangular pool = w m

Formula, to calculate the perimeter of a rectangle is given by,

Perimeter = 2(Length + width)

By substituting values in the formula,

154 = 2(l + w) --------(1)

Since, "length of the pool is 2 m more than twice of its breadth"

l = 2 + 2w ---------(2)

Bu substituting value of 'l' from equation (2) to equation (1),

154 = 2[(2 + 2w) + w]

154 = 2(3w + 2)

77 = 3w + 2

3w = 75

w = 25 m

From equation (2),

l = 2 + 2(25)

l = 2 + 50

l = 52 m

Therefore, length of the rectangular pool is 52 m and width is 25 m.

There's a slight problem with your question, but we'll get to that...

Consecutive terms of the sequence are separated by a fixed difference of 21 (22 = 1 + 21, 43 = 22 + 21, 64 = 43 + 21, and so on), so the n-th term of the sequence, a (n), is given recursively by

• a (1) = 1

• a (n) = a (n - 1) + 21 … … … for n > 1

We can find the explicit rule for the sequence by iterative substitution:

a (2) = a (1) + 21

a (3) = a (2) + 21 = (a (1) + 21) + 21 = a (1) + 2×21

a (4) = a (3) + 21 = (a (1) + 2×21) + 21 = a (1) + 3×21

and so on, with the general pattern

a (n) = a (1) + 21 (n - 1) = 21n - 20

Now, we're told that the sum of some number N of terms in this sequence is 2332. In other words, the N-th partial sum of the sequence is

a (1) + a (2) + a (3) + … + a (N - 1) + a (N) = 2332

or more compactly,

[tex]\displaystyle\sum_{n=1}^N a(n) = 2332[/tex]

It's important to note that N must be some positive integer.

Replace a (n) by the explicit rule:

[tex]\displaystyle\sum_{n=1}^N (21n-20) = 2332[/tex]

Expand the sum on the left as

[tex]\displaystyle 21 \sum_{n=1}^N n-20\sum_{n=1}^N1 = 2332[/tex]

and recall the formulas,

[tex]\displaystyle\sum_{k=1}^n1=\underbrace{1+1+\cdots+1}_{n\text{ times}}=n[/tex]

[tex]\displaystyle\sum_{k=1}^nk=1+2+3+\cdots+n=\frac{n(n+1)}2[/tex]

So the sum of the first N terms of a (n) is such that

21 × N (N + 1)/2 - 20N = 2332

Solve for N :

21 (N ² + N) - 40N = 4664

21 N ² - 19 N - 4664 = 0

Now for the problem I mentioned at the start: this polynomial has no rational roots, and instead

N = (19 ± √392,137)/42 ≈ -14.45 or 15.36

so there is no positive integer N for which the first N terms of the sum add up to 2332.
