An integer is chosen between 0 and 100. What is the probability that it is divisible by 7?

1 answer:

IgorC [24]3 years ago

Assuming 0 and 100 are included in the possible choices:

There are $\left\lfloor\dfrac{101}7\right\rfloor=14$ multiples of 7 between 0 and 100, so there is a $\dfrac{14}{101}\approx0.1386$ probability of choosing a multiple of 7.

Find the slope of the line through each pair of points

NNADVOKAT [17]

The formula of a slope:

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

95)

$(-13,\ -10)\to x_1=-13,\ y_1=-10\\(16,\ 16)\to x_2=16,\ y_2=16$

substitute:

$m=\dfrac{16-(-10)}{16-(-13)}=\dfrac{16+10}{16+13}=\dfrac{26}{29}$

96)

$(6,\ -16)\to x_1=6,\ y_1=-16\\(-15,\ 9)\to x_2=-15,\ y_2=9$

substitute:

$m=\dfrac{9-(-16)}{-15-6}=\dfrac{25}{-21}=-\dfrac{25}{21}$

97)

$(12,\ -11)\to x_1=12,\ y_1=-11\\(14,\ -12)\to x_2=14,\ y_2=-12$

substitute:

$m=\dfrac{-12-(-11)}{14-12}=\dfrac{-12+11}{2}=-\dfrac{1}{2}$

OK. I think you already know how to solve it. I will give short solutions now.

98)

$m=\dfrac{15-(-3)}{8-(-14)}=\dfrac{18}{22}=\dfrac{9}{11}$

99)

$m=\dfrac{3-(-5)}{-7-3}=\dfrac{8}{-10}=-\dfrac{4}{5}$

100)

$m=\dfrac{-8-8}{-11-0}=\dfrac{-16}{-11}=\dfrac{16}{11}$

101)

$m=\dfrac{13-(-5)}{-13-(-13)}=\dfrac{18}{0}!!!-\boxed{NOT\ EXIST}$

102)

$m=\dfrac{18-1}{-10-2}=\dfrac{17}{-12}=-\dfrac{17}{12}$

103)

$m=\dfrac{19-14}{7-(-17)}=\dfrac{5}{24}$

104)

$m=\dfrac{12-0}{-6-4}=\dfrac{12}{-10}=-\dfrac{6}{5}$

QUESTION NUMBER 15 TNANKYOU!!!

slavikrds [6]

Volume of a triangular prism is given by V = Al where A is the area of the triangular cross section, i.e. $A= \frac{1}{2}bh$ , and l is the length of the triangular prism.
Here, b = 8cm, h = 9cm, and l = 5cm.
$A= \frac{1}{2}bh= \frac{1}{2} \times8 \times9=4\times9=36cm^{2}$
Therefore, $V=Al=36\times5=180cm^{3}$
