kompoz [17]

Answer:

c. 0.1151

Step-by-step explanation:

d) the probability that, on average, fish are larger than 86 centimeters in length.The area under part of a normal probability curve is  directly proportional to probability and the value is calculated as

z = (x₁−x) /σ

where z = propability of normal curve

x₁ = variate mean = 86cm

x = mean of 80cm

σ = standard deviation = 5cm

applying the formula,

z= (86-80)/5

z = 6/5 =1.2

Using a table of partial areas beneath the standardized normal curve (see Table of normal curve, a z-value of 1.2 corresponds to an area of 0.3849 between the mean value. but, because the standard curve has 0.5, then will minus 0.3849 from 0.5= 0.5 - 0.3849 = 0.1151

Thus the probability of a fish are larger than 86 centimeters in length is 0.1151

The location of point V is (-3,3). The location of point X is (9,13). Determine the location of point W which is 3/4 of the way
Inga [223]

ANSWER

W(\frac{9}{7},\frac{51}{7} )

EXPLANATION

We want to find the coordinates of the point W(x,y) which divides V(-3,3) and X(9,13) in the ratio m:n=3:4.

The x-coordinate of this point is given by:

x= \frac{mx_2+nx_1}{m + n}

x= \frac{3(9)+4( - 3)}{4 + 3}

x= \frac{21 - 12}{4 + 3}

x= \frac{9}{7}

The y-coordinates is given by;

y= \frac{my_2+ny_1}{m + n}

y= \frac{3(13)+4( 3)}{4 + 3}

y= \frac{39+12}{4 + 3}

y= \frac{51}{7}

Hence

W(\frac{9}{7},\frac{51}{7} )

[REALLY EASY QUESTION]
AVprozaik [17]

Answer:

A. h(x)=4x+2

Step-by-step explanation:

Because it's shifted to the left, you would subtract three units from 5, resulting in 4x+2. Hope this helps, have a nice day! :)
