Natalka [10]

Answer: the probability that a randomly selected Canadian baby is a large baby is 0.19

Step-by-step explanation:

Since the birth weights of babies born in Canada is assumed to be normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = birth weights of babies

µ = mean weight

σ = standard deviation

From the information given,

µ = 3500 grams

σ = 560 grams

We want to find the probability or that a randomly selected Canadian baby is a large baby(weighs more than 4000 grams). It is expressed as

P(x > 4000) = 1 - P(x ≤ 4000)

For x = 4000,

z = (4000 - 3500)/560 = 0.89

Looking at the normal distribution table, the probability corresponding to the z score is 0.81

P(x > 4000) = 1 - 0.81 = 0.19

Eddi Din [679]

Answer:

Natalie have left with 5 beads.

Step-by-step explanation:

Given:

Natalie had 64 beads. She used 24 beads to make a bracelet. She used 7/8 of the remaining beads to make a necklace.

Now, to find the beads does Natalie have left.

Total beads Natalie had = 64 beads.

And beads she used to make a bracelet = 24 beads.

So, the remaining beads are = $64-24=40\ beads.$

Now, the beads she used to make a necklace = $40 of \frac{7}{8}$

= $40\times \frac{7}{8}$

= $\frac{280}{8}$

= $35\ beads$

Hence, the beads Natalie have left = remaining beads - beads used to make necklace.

$The\ beads\ Natalie\ have\ left\ =\ 40-35$

$The\ beads\ Natalie\ have\ left\ =\ 5\ beads.$

Therefore, Natalie have left with 5 beads.
