A particular fruit's weights are normally distributed, with a mean of 476 grams and a standard deviation of 36 grams. The heavie
4vir4ik [10]

Answer:

Step-by-step explanation:

Given that:

mean (μ) = 476 grams, standard deviation (σ) = 36 grams. P(z) = 19%

The z score shows by how many standard deviation the raw score is above or below the mean. It is given by the equation:

z=\frac{x-\mu}{\sigma}

Since the 19% weigh more, therefore 81% (100% - 19%) weigh less.

From the normal distribution table, the z score that corresponds to a probability of 81%(0.81) = 0.87

We substitute z = 0.88 in the z score equation to find the raw score. Therefore:

z=\frac{x-\mu}{\sigma}\\0.87=\frac{x-476}{36}\\ x-476=31.32\\x=31.32+476\\x=507.32\\

x ≅ 507 grams

Therefore 19% of fruits weigh more than 507 grams

10w + 4w = -84 solve by combining like terms show all steps leading to awnser plz
Ira Lisetskai [31]
10w + 4w = - 84
14w = - 84
w = - 84 : 14
w = - 6  (  answer )
-----------------------------------
10 * (- 6) + 4 * (- 6) = - 84
            - 60 + (- 24) = - 84
                         - 84 = - 84

76 19 in ratio simplest form
Nata [24]
Putting the two numbers together in fraction form of a ratio, we have 76/19. We know that something multiplied by 19 will equal to 76.

When we try to multiply 4 and 19 together, we have our nice answer 76. We then replace out values in the original ratio, in which we get the final answer of 4:1, 4/1, or 4 to 1.
