Answer:

52°

Step-by-step explanation:

Since, measure of minor arc is equal to the measure of its corresponding central angle.

$\therefore m\widehat{ED} = m\angle ECD\\\because m\angle ECD = 104°\\\purple {\bold {\therefore m\widehat{ED} = 104°}} \\$

Now by inscribed angle theorem:

$m\angle EQD = \frac{1}{2} \times m\widehat{ED}\\\\\therefore m\angle EQD = \frac{1}{2} \times 104°\\\\\huge \red {\boxed {\therefore m\angle EQD = 52°}} \\$

in a survey of a town, 56% of residents own a car, 21% of residents owns a truck, and 4% of residents own both a car and a truck

maksim [4K]

define two events $A=\{owns \; a\; car\},B=\{owns \; a\; truck\}$ .

From the information given,

$P(A)=\frac{56}{100}=0.56 \\ P(B)=\frac{21}{100}=0.21\\ P(AB)=\frac{4}{100}=0.04$

The conditional probability,

a person owns a truck given the person who owns a car is

$P(B|A)=\frac{P(AB)}{P(A)} \\ P(B|A)=\frac{0.04}{0.56} \\ P(B|A)=0.071$

Answer:

x = 7

Step-by-step explanation:

4x + 5 = x + 26

4x - x = 26 - 5

3x = 21

x = 21/3

x = 7

Check:

4*7 + 5 = 7 + 26

28 + 5 = 33

Use the calculator to evaluate the function y = 1 *2 - 2 for the given values of x.

krok68 [10]

Answer:

when x= -4, y= 2

when x= 6, y =7

Step-by-step explanation:

We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2

first we do the exponent

y= 1/4 (16) - 2

Then the multiplication

y= 4-2

then subtraction

y=2

For the second problem, it becomes y= 1/4 (6)^2 -2 We follow the same steps

y = 1/4 (36) - 2

y= 9-2

y= 7
