Think of it as a(b+c)=ab+ac or using subtraction
so: x(8+9)= x8+x9

H=10 cm r= 7cm calculate the volume of the cylinder

Stels [109]

Answer:

V = 1538.6 cm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h where r is the radius and h is the height

V = pi (7)^2 10

V = 3.14 (49)10

V = 1538.6 cm^3

Since 1936, the Gallup Organization has been asking Americans: "Are you in favor of the death penalty for a person convicted of

USPshnik [31]

Answer:

98% confidence interval for the proportion of all American females who support the death penalty for convicted murders is [0.59 , 0.64].

Step-by-step explanation:

We are given that the results of the most recent survey; in a sample of 3100 females, 62% said that they were in favor of the death penalty for convicted murders.

Firstly, the pivotal quantity for 98% confidence interval for the population proportion is given by;

P.Q. = $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ ~ N(0,1)

where, $\hat p$ = sample proportion of females who were in favor of the death penalty for convicted murders = 62%

n = sample of females = 3100

p = population proportion of all American females who support the death penalty

Here for constructing 98% confidence interval we have used One-sample z proportion statistics.

So, 98% confidence interval for the population proportion, p is ;

P(-2.33 < N(0,1) < 2.33) = 0.98 {As the critical value of z at 1% level

of significance are -2.33 & 2.33}

P(-2.33 < $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ < 2.33) = 0.98

P( $-2.33 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ < ${\hat p-p}$ < $2.33 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ ) = 0.98

P( $\hat p-2.33 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ < p < $\hat p+2.33 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ ) = 0.98

98% confidence interval for p = [ $\hat p-2.33 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ , $\hat p+2.33 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ ]

= [ $0.62-2.33 \times {\sqrt{\frac{0.62(1-0.62)}{3100} } }$ , $0.62+2.33 \times {\sqrt{\frac{0.62(1-0.62)}{3100} } }$ ]

= [0.59 , 0.64]

Therefore, 98% confidence interval for the proportion of all American females who support the death penalty for convicted murders is [0.59 , 0.64].

Abc is a right angle decomposed into 2 non overlapping angles. Abd and dbc. What kind of angle is dbc

wariber [46]

Answer:

The answer is " $m \angle ABD = 45^{\circ} \ \ and \ \ m \angle DBC = 45^{\circ}\\\\$ "

Step-by-step explanation:

In this question, the adjacent angles aren't overlapping, and that they have the shared widely and have the common side. There ABC does have the correct angle, which includes two not overlapping ABD and DBC angles with such a joint B vertex and BD lines. Now it is constructed. Thus both angles are not overlapping:

$m \angle ABD = 45^{\circ}\\\\m \angle DBC = 45^{\circ}\\\\or \ \ \text{the angles will may be} \\\\m \angle ABD = 35^{\circ}\\\\m \angle DBC = 55^{\circ}\\\\$
