Step-by-step explanation:

Given

base (BD)= 7 cm

Height (CE) = 4 cm

BC = 5.7 cm

CD = 5 cm

Now

Perimeter of the triangle

= BD + BC + CD

= 7 + 5.7 + 5

= 17.7 cm

Now

Area of the triangle

= 1/2 * base * height

= 1/2 * 7 * 4

= 14 cm²

Hope it will help :)❤

En una tienda de electrodomésticos, un refrigerador costaba $8,900 y rebajaron su precio a $7,120 ?Cuál fué el porcentaje que le

Mamont248 [21]

Answer:

$20\%$

Step-by-step explanation:

The question in English is

In one appliance store, a refrigerator cost $8,900 and they lowered it to $7,120. What percentage did they lower?

we know that

$8,900 ------> represent the 100%

by proportion

$\frac{100\%}{\$8,900}=\frac{x\%}{\$7,120}\\ \\x=7,120*(100\%)/8,900\\ \\x=80\%$

therefore

the percentage is equal to

$100\%-80\%=20\%$

5. A company sells small, colored binder clips in packages of 20 and offers a money-back guarantee if two or more of the clips a

SOVA2 [1]

Answer:

a) Binomial.

b) n=20, p=0.01, k≥2

The probability hat a package sold will be refunded is P=0.0169.

Step-by-step explanation:

a) We know that

the defective probability is constant and independent.
the sample size is bigger than one subject.

The most appropiate distribution to represent this random variable is the binomial.

b) The parameters are:

Sample size (amount of clips in the package): n=20
Probability of defective clips: p=0.01.
number of defective clips that trigger the money-back guarantee: k≥2

The probability of the package being refunded can be calculated as:

$P(x\geq2)=1-(P(x=0)+P(x=1))\\\\\\P(x=k) = \dbinom{n}{k} p^{k}q^{n-k}\\\\\\P(x=0) = \dbinom{20}{0} p^{0}q^{20}=1*1*0.8179=0.8179\\\\\\P(x=1) = \dbinom{20}{1} p^{1}q^{19}=20*0.01*0.8262=0.1652\\\\\\P(x\geq2)=1-(0.8179+0.1652)=1-0.9831=0.0169$
