Answer:

<em>Heidi'd mom made 32 rose arrangements and 8 tulip arrangements.</em>

Step-by-step explanation:

Let the number of rose arrangements be = x

Let the number of tulip arrangements be = y

Heidi's mom made 4 times as many rose arrangements as tulip arrangements.

We get the equation;

x=4y        

Heidi's mom made 40 arrangements. We get the second equation:

x+y=40          

Substituting the value of x from first equation to second equation, we get

4y+y=40

=> 5y=40

Dividing both sides by 5;

y = 8

And x = 4y

So, x=4(8)=32

x = 32

<em>Hence, Heidi'd mom made 32 rose arrangements and 8 tulip arrangements.</em>

The formula for the confidence interval is given by

Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]

We have:
Sample mean = 23.95
n = 40 
σ = 2.55
z* for 99% confidence = 2.58

Substitute these values into the formula, we have

23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91

So the lower interval is 22.91 and the highest interval is 24.99

Solve. (K+1)(k-5)=0<br> Explin how to solve ???
Anna71 [15]
Alright remember, if any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0. 
k+1=0
k-5=0
Set the first factor equal to 0 and solve
k=-1
Set the next factor equal to 0 and solve
k=5
The final solution is all the values that make (k+1)(k-5)=0 true. 
k=-1, 5

Hope this helped you out :)
