The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 4016
hodyreva [135]

Answer:

Required Probability = 0.97062

Step-by-step explanation:

We are given that the weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 4016 grams and a standard deviation of 532 grams.

Let X = weight of the newborn baby, so X ~ N(\mu=4016 , \sigma^{2} = 532^{2})

The standard normal z distribution is given by;

              Z = \frac{X-\mu}{\sigma} ~ N(0,1)

Now, probability that the weight will be less than 5026 grams = P(X < 5026)

P(X < 5026) = P( \frac{X-\mu}{\sigma} < \frac{5026-4016}{532} ) = P(Z < 1.89) = 0.97062

Therefore, the probability that the weight will be less than 5026 grams is 0.97062 .

Solve for h please and thank you
KonstantinChe [14]

Answer:

35° (I may be wrong)

Step-by-step explanation:

An isosceles triangle has an interior angle sum of 180° (like all triangles).

So...

180°-40°= 140°

And because we know that isoceles triangles and two congruent sides, we just have to divide 140° by 2.

140°÷2=70°

But the picture says 2h and h is a side so...

70°÷2=35°
