Priscilla can make 2 bracelets in 12 minutes. At this rate, how many bracelets can she make in 48 minutes?

Leto [7]

Answer: Priscilla can make 8 bracelets in 48 minutes.

Step-by-step explanation:

So the givens are that:

2 bracelets in 12 minutes, how many in 48 minutes

So find the ratio of bracelets to minutes:

2/12 simplified is 1/6

So Priscilla can make 1 bracelet per 6 minutes. We just need to find how many in 48 minutes.

1/6 * 8 = 8/48

So Priscilla can make 8 bracelets in 48 minutes.

Hence your answer.

Please help on this question.

Sonbull [250]

Answer:

Step-by-step explanation:

$\frac{ - 20 {x}^{2} + 14x + 12}{5x - 6} \\ \\ = \frac{- (20 {x}^{2} - 14x - 12)}{5x - 6} \\ \\ = \frac{ - (5x - 6)(4x + 2)}{5x - 6} \\ \\ = - (4x + 2 ) \\ = - 4x - 2$

Domain:

g(x) ≠ 0

$5x - 6 = 0 \\ 5x = 6 \\ \\ x = \frac{6}{5}$

All real numbers ≠ 6/5

For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is

Aleksandr-060686 [28]

For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is

Answer: We are required to find the value of z corresponding to probability 0.8340.

i.e., $P(Z$

We can find the value of z using the standard normal table.

Using the standard normal table, we have:

$z(0.8340)=0.97$

Therefore, for the value of z = 0.97, cumulative standardized normal distribution is 0.8340

Attached here standard normal table for your reference.

What is the difference between linear and exponential function?

sp2606 [1]

Linear functions change at a constant rate per unit interval and take the form y=mx+b, while exponential functions change by a common ratio over equal intervals and take the form y=a^x.
