Answer:

4 scrunchies

Step-by-step explanation:

GIVEN :

Sara can spend up to $24.98.

She already spent $12.99

She wants scrunchies that are $3.00 each.

To Find : No. of scrunchies She can purchase.

Solution :

Since she can spend up to  $24.98.

She already spent $12.99

So, amount she can spend further = $24.98-$12.99 = $11.99

Now she wants to buy scrunchies

No. of scrunchies of $3.00 = 1

No. of scrunchies of $1.00 = 1/3

No. of scrunchies of  $11.99 :


= \frac{1}{3} *11.99


⇒ 3.99


Thus no. of scrunchies of $11.99 =3.99≈4

Hence she can buy 4 scrunchies

First differences are 2, 4, 8, 16, which is a geometric sequence. The parent function is not linear (constant first difference) or quadratic (first difference increases by the same amount from one to the next). When the first differences are a geometric sequence, the underlying sequence is a geometric (exponential) sequence.

1st blank: exponential

Translation up adds a constant to each of the f(x) values.

2nd blank: f(x)
3rd blank: increased by 5<span>

For the last blank, you're looking for an (x, f(x)) pair that is translated to (x, f(x)+5).

This table shows some values of an exponential function. x у 01.25 1 2.50 25 3 10 What is the function?​
Helen [10]

Answer:

y= 1.25(2)^{x}

Step-by-step explanation:

y= 1.25(2)^{x}

For x=0

y= 1.25(2)^{0} = 1.25

For x=1

y= 1.25(2)^{1} = 1.25(2)=2.5

For x=2

y= 1.25(2)^{2} = 1.25(4)=5

For x=3

y= 1.25(2)^{3} = 1.25(8)=10

The Sum of 4 times one number and 3 times the second number is 65. The sum if the 2 numbers is 18. What are the numbers and equa
nalin [4]
4x + 3y = 65
X + y = 18

When you use elimination, multiply the second equation by -3
4x + 3y = 65
-3X -3y = -54
X = 11


X+y = 18
11 + y = 18
Y = 7

The probability of being a universal donor is 6% (O-negative-blood type). Suppose that 6 people come to a blood drive.' a) What
Tcecarenko [31]

Answer:

Mean = 0.36

SD = 0.5817

P(x=3) = 0.003588

Step-by-step explanation:

Given

Let

A = Event of being a universal donor.

So:

P(A) = 0.06

n = 6

Solving (a): Mean and Standard deviation.

The mean is:

Mean = np

Mean = 6 * 0.06

Mean = 0.36

The standard deviation is:

SD = \sqrt{np(1-p)}

SD = \sqrt{6*0.06*(1-0.06)}

SD = \sqrt{0.3384}

SD = 0.5817

Solving (b): P(x = 3)

The event is a binomial event an dthe probability is calculated as:

P(x) = ^nC_x * p^x * (1-p)^{n-x}

So, we have:

P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^{6-3}

P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^3

P(x=3) = 20 * 0.06^3 * (1-0.06)^3

P(x=3) = 0.003588
