Can someone help me find the answer?

raketka [301]

Answer:

AC=9 cm

ABC is not a right angled triangle

Step-by-step explanation:

AB=8cm

BC=5cm

22=AB+BC+AC

AC=22-8-5

AC=9

since AC is the longest,

using Pythagoras theorem

AC^2=BC^2+AB^2

9^2=8^2+5^2

81=64+25

81=89

therefore, it is not a right angled triangle

When you mix two colors of paint in equivalent ratios, the resulting color is

vredina [299]

Answer:

Step-by-step explanation:

From the given table,

To prepare a mixture of a paint, two paints of different shades have been added in the same ratio,

Since, 2 cups of blue paint are mixed with 10 cups of yellow paint

Therefore, ratio in which these shades have been added = $\frac{\text{Pink}}{\text{Blue}}$

= $\frac{10}{2}$

= $\frac{5}{1}$

= 5 : 1

For 1 cup of blue paint number of cups of yellow paint required,

$\frac{x}{1}=\frac{5}{1}$

x = 5 cups

For 3 cup of blue paint number of cups of yellow paint required,

$\frac{x}{3}=\frac{5}{1}$

x = 15 cups

Cups of blue paint Cups of yellow paint

The probability distribution for a

Tpy6a [65]

Answer:

$P(x \le -3) =0.30$

Step-by-step explanation:

Given

The attached probability distribution of x

Required

Find $P(x \le -3)$

To do this, we consider all values of x less than or equal to-3.

So, we have:

$P(x \le -3) =P(x=-5) + P(x = -3)$

From the table:

$P(x=-5) = 0.17$

$P(x = -3) = 0.13$

So, the equation becomes

$P(x \le -3) =P(x=-5) + P(x = -3)$

$P(x \le -3) =0.17 + 0.13$

$P(x \le -3) =0.30$
