None of the statements seem to be true. Essentially, the following should be true

0.4>0.06 because 4/10 > 6/100

0.4 > 0.06 because 4 tenths is greater than 6 hundredths

Step-by-step explanation:

To decide which decimal number is bigger, we first check the whole numbers (on the left of the decimal point). If the whole numbers are similar we move to the tenths number (on the right of the decimal point)

We compare the tenths numbers. Whichever has the greatest number is the greater of th two decimal numbers.

If the tenths numbers are similar, we move to the hundredths. The one with the largest number is the greater of the two.

If they are similar we move to the thousandths number and so on...

until we can resolve the two numbers

The equation of a circle is (x + 6)^2 + (y - 4)^2 = 16. The point (-6, 8) is on the circle.

pantera1 [17]

Answer:

y = 8 is the equation of tangent.

Step-by-step explanation:

The equation of the tangent to the circle at (-6,8) is of the form:

y = mx + c

where m is the slope of the tangent and c is the y-intercept.

The point (-6,8) lies on the circle and the tangent line as well.

Hence (-6,8) satisfies the line equation:

8 = m(-6) + c ⇒ c-6m = 8 -------------1

We know that slope of two perpendicular lines are related as:

$m_{1}\times m_{2}=-1$

At any point on the circle, the normal line at a point is always perpendicular to the tangent line at that point.

Hence :

$m_{normal} \times m_{tangent}=-1$

We can find the slope of the normal at point (-6,8) as it passes through the centre of the circle (-6,4) by using the two-points formula for slope.

$m=\frac{y_2-y_1}{x_2-x_1}$

$=\frac{8-4}{-6+6}$

= ∞

Slope of the normal is infinity and hence slope of tangent is -1/∞ = 0

Hence m=0

Putting m=0 in equation 1 we get:

c = 8

The equation of tangent line at (-6,8) is:

y = 8

The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard devi

son4ous [18]

Answer:

Step-by-step explanation:

Since the length of time taken on the SAT for a group of students is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - u)/s

Where

x = length of time

u = mean time

s = standard deviation

From the information given,

u = 2.5 hours

s = 0.25 hours

We want to find the probability that the sample mean is between two hours and three hours.. It is expressed as

P(2 lesser than or equal to x lesser than or equal to 3)

For x = 2,

z = (2 - 2.5)/0.25 = - 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.02275

For x = 3,

z = (3 - 2.5)/0.25 = 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.97725

P(2 lesser than or equal to x lesser than or equal to 3)

= 0.97725 - 0.02275 = 0.9545

Can someone help me out ASAP and possible step by step

OlgaM077 [116]

Answer:

49°

Step-by-step explanation:

The given information that BC=DC tells you triangle BCD is an isosceles triangle and that angle y is one of the two equal base angles. Then ...

y + y + 82 = 180 . . . . . the sum of angle measures is 180 degrees

2y = 98 . . . . subtract 82

y = 49 . . . . . divide by 2

The measure of y is 49°.
