Fine the equation of the line that is perpendicular to the given line and passes through the given point. Enter the right side o
Kipish [7]

Answer:

y=-\frac{4}{7} x+\frac{55}{7}

Step-by-step explanation:

Change the given equation to slope-intercept to get y=\frac{7}{4}x-\frac{1}{4}. When you multiply the slopes of perpendicular lines, you get -1. -1 divided by \frac{7}{4} is -\frac{4}{7}. The slope of the new line is then -\frac{4}{7}. The perpendicular line passes through (5, 5) so you can have the equation5=-\frac{4}{7} (5)+b. Simplifying gets b = \frac{55}{7} . So now the final equation for the perpendicular line is y=-\frac{4}{7} x+\frac{55}{7}

. A survey found that women spend on average $146 on beauty products during the summer months. Assume the standard deviation is
arsen [322]

Answer:

69.1% of the woman spend less than $160

Step-by-step explanation:

Assuming that the random variable X= spend on beauty products by women during summer months distributes normally , then using the standarized variable Z:

Z= (X - mean / st. dev) = (160.00-146 )/28 = 0.5

then using normal probability tables for Z:

P(X<160)=P(Z<0.5) = 0.691 (69.1%)

thus 69.1% of the woman spend less than $160
