Answer:

<u>Given</u>

ΔTQR is right
QS is altitude
ΔRSQ and ΔTSQ also right
m∠TQS = 42°, RS = 26 cm

∠RQS and ∠TQS are complementary with ∠TQS, so are 48°

∠QRS is the another one with 42°

<u>Find QS first</u>

26/QS = tan 48°
QS = 26 / tan 48° = 23.4

QS/QT = cos 42°
QT = QS / cos 42° = 23.4 / cos 42° = 31.5 (rounded)

The eqaution d=m/v can be used to calculate the density d an object with a mass and volume v. Which is an equivalent equation so

kodGreya [7K]

v = $\frac{m}{d}$

given d = $\frac{m}{v}$

multiply both sides of the equation by v, hence

dv = m ( divide both sides by d )

v = $\frac{m}{d}$

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on th

ddd [48]

Answer:

the weighted score is 82.03

Step-by-step explanation:

The computation of the weighted score is as follows

= Respective scores × respective test or exam and score

= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79

= 18.9 + 21.6 + 17.04 + 24.49

= 82.03

Hence, the weighted score is 82.03

We simply applied the above formula so that the weighted score could be come

Choose the equation that represents the line passing through the point (2, - 5) with a slope of −3.

zzz [600]

<h2>Answer:</h2>

We must determine the y-intercept, b using the slope and point provided.

$-5 = -3(2) + b\\\\-5 = -6 + b\\\\1 = b$

Now that we know the y-intercept, b, we can create the equation of this line: <em>y = -3x + 1</em>.

Can someone find the surface area of the picture below.

Sonja [21]

The area of each of the 4 triangles is

... A = (1/2)bh = (1/2)(4)(3) = 6

The area of the square base (in the center of the net diagram) is

... A = s² = 4² = 16

Then the total area is 4×6 + 16 = 40 square units.

Assume that we have m coins. We toss each one of them n times. The probability of heads showing up for each coin isp. What’s the

olga nikolaevna [1]

Answer:

$1-(1-p^n)^m$

Step-by-step explanation:

For a coin, the probability of head showing in a single toss is $p$ .

$P(H)=p$

Its complement, the probability of not head is

$P(\Sim H)=1-p$

This is a binomial distribution. In $n$ tosses, the probability of having all heads (i.e. $n$ heads) is

$P(\text{all heads})=\binom{n}{n}p^n(1-p)^0=p^n$

Let's call this value $a$ .

For $m$ coins, we determine the probability of at least 1 coin showing all heads by first finding its complement i.e. the probability of no coin showing all heads. This is also a binomial distribution.

$P(\text{no coin showing all heads})=\binom{m}{0}a^0(1-a)^m=(1-a)^m$

$P(\text{at least 1 coin showing all heads})=1-P(\text{no coin showing all heads})$

$P(\text{no coin showing all heads})=1-(1-a)^m=1-(1-p^n)^m$
