Answer:
3:4
Step-by-step explanation:
find the GCD of both numbers (30) and divide both sides to get 3:4
Null: the mean amount of peanut butter in a jar is equal to 32 oz.
alternative: the mean amount of peanut butter in a Jar is less than 32oz.
type 1 error is is rejecting the null when it is actually true. this means that we would say that the mean amount of peanut butter is not equal to 32 when it actually is.
type 2 error is failing to reject the null when it is actually false. this means that we would say the mean amount of peanut butter is equal to 32 when in reality it is less.
In scientific notation, you must move the "invisible decimal point" until there is a one-digit number, sometimes followed by a decimal of more numbers. Then, how ever many digits you had to move it is the exponent to the number 10.
Example:
1200.
120.0
12.00
1.200
Since the decimal had to move 3 places, the scientific notation of this is:
1.2 • 10^3
In this question, the decimal must move 9 places left before resulting in 1.322.
So the answer, in scientific notation, is 1.322 • 10^9.
The correct answer is A. <span>The independent variable is the temperature of the water, and the dependent variable is the amount of sugar dissolved. The independent variable is the one that isn't affected by any of the other variables. The dependent variable is the one being studied, measured, and affected in the experiment. Obviously, Eman wants to measure the amount of sugar that dissolves in water.</span>
Answer:
Voir ci-dessous.
Step-by-step explanation:
1.
OA/OD = 36/64 = 9/16
OB/OC = 27/48 = 9/16
m<AOB = m<COD
triangle AOB ~ trianlge DOC
m<BAO = m<CDO
AB || CD
2.
AB/CD = OA/OD
AB/80 = 36/64
AB/80 = 9/16
16AB = 9 × 80
AB = 9 × 5
AB = 45
AB = 45 cm
3.
AB = 45
BC = OC + OB = 48 + 27 = 75
AB² + AC² = BC²
45² + AC² = 75²
AC² = 5625 - 2025
AC = √3600
AC = 60 cm
hauteur = 5 × 2 cm + 4 × 60 cm
hauteur = 10 cm + 240 cm
hauteur = 250 cm
